Help with an STU setup, please?
�
�
Ok, I am going to be getting an 05 STi. I was sooooo tempted to get an EVO (even giving me a killer deal over what the Sube dealer would - he wanted my 04 STi in trade bad - even willing to pay it off completely way over Blue Book!), but driving one, to me at least, is frustration with the lack of low end! And the MR won't be out till mid to late next year I was told. But I just can't get Sube out of my system, soooooo . . . . .
With the newer goodies in the 05 STi, it appears to be a better base to build an STU car from than my current 04. So, I need some of your expert thoughts on this. Here are some of my thoughts:
Curious about the new SPT "Pink" coilovers
Would the Tein electrically adjustable coilovers be allowed in STU? Would make adjusting the rears much easier not having to remove the back seats :banana:
Cobb or Hotchkis swaybars and links
Is the ALK legal yet or not? Otherwise I guess the Whiteline bushings?
PDE has some sharp looking camber plates that also adjust caster!!!
Or just go with KONI double adjustables and Eibach (or H&R, or whoevers) springs = KISS (Keep It Simple, Stupid)
Get rid of that fat old fart driver (me)
Cobb Access Port (do they have an STU flash???)
Group N mounts
STi short shift kit
I currently have the Stromung 3" cat-back, what would be a good STU legal downpipe - and one that would PASS SMOG, and perhaps be able to pass a SMOG visual inspection under the car :devil: Oh, and not give boost creep with the current Stromung
Would that new Cobra [URL=http://www.subesports.com/products/?cartID=20040926185636216.249.104.210&cat=Seating&brand=Cobra&prodID=670]Missano R[/URL] seat be legal in STU?
Would some Type R decals give me more HP???? :D
Would some stiffer steering rack bushings be legal?
Tire choices:
1) BFG KD's in 245/40/17
2) Kumho MX 245/40/17
3) Falken Azenis 245/45/17
Or go with 18's? But that would really limit tire choices.
Anything else I am missing?
Thanks

Steering rack modifications would bump you into StreetMod I believe?
And is this Cobra seat reclinable? If it so, youre good.
You should read the autoX rulebook thing on the main page, it might help ya out =)

Yea, the Type ARR stickers add HP, but they also add weight. Keep the power to weight ratio in mind when doing this mod

Yes, the Cobra is a recliner, BUT . . . . it is a carbon fiber back. And is it LIGHT! That is why I am concerned if it really would be legal.
As for the rules in the sticky, I was going through them a bit, but 30+ pages is quite a bit when you are in a bit of a hurry as I will be getting the 05 in a few days and wanted to try and include as much as possible in the package (loan). Also, 30+ pages is a bit, errrr a mess when not much is said about specific parts. I pretty much know most of what would be legal in STX, but what brand parts (and ones proven to work) is more my questions :)

Well I wont be able to help ya out oo much in that department being a noob
But according to the thread, a seat OVER 15 lbs is Street Touring legal.

Don't need a reclinable seat in STX/STU (and I *think* STS too now). All that is needed is a fully upholsetered seat weighing in at 15lbs with mounting hardware.
And decals ALWAYS add HP.

Don't the stock seats have airbags in them? If they do, I don't think you can swap them out.
I think the 05 steering rack bushings were upgraded, so you don't need to touch them.

Just a slight clarification. The seat has to weight at least 15 lbs. WITHOUT the mounting hardware.
Also the seat doesn't have to be fully upholstered, it only has to have upholstery on the seating surfaces. A Kirkey seat with a seat cover is perfectly legal as long as it's at least 15 lbs.

ALK isn't even legal in SM. The caster bushings you can do, however camber/caster plates would just be a lot simpler.
I'd recommend sticking with 17" tires for rotational weight issues, along with tire choice issues.
As long as you have at least a high-flow cat in the Stromung somewhere (within 6" of the original primary cat location) you should be fine.
The Tein electronic-gizmo-whizbang suspension is not legal. Neither is the Praxis. SPT Pink springs? Legal. The new STi coilovers? Also legal. Competitive? Nobody knows yet.
As far as the AccessPort, I'm not sure it's legal...you would have to do further investigation. :)

Hmmm, so is this true? Would mean a lot of the new ST cars would NOT be able to replace their seats then. And if yours came stock with a slider (no bolstering), you are screwed.

Yes, you can replace airbag-equipped seats in ST. There was a proposal floated this Summer by the SEB to not allow replacement of airbag-equipped seats, but it was withdrawn, due to negative member feedback.

You can have the EDFC unit BUT you can't run with the control unit connected. Technically, you can adjust it and then disconnect the unit. IMO, this is a grey area. Who's to say that there isn't a hidden control unit? I haven't seen a clarification on the legality of the part. Personnaly I wouldn't take the chances and just go without the EFDC.

ALKs are not legal. I'm not sure about the Whiteline offset bushings (see my comments about combo caster/camber plates).

[/quote]
IMO, combination caster/camber plates are questionable. There's allowances in the rules for camber plates, but there is no mention of caster/camber plates. The rule states caster changes as a result of using camber plates are allowed. But it does not specifically allow active castor adjustment.

I wouldn't use any of the "lowering" springs that's on the market. Most of them don't have the rates that's needed for Auto-X, they're mainly designed for "looks" than for performance.

Cobb Access Port (do they have an STU flash???)
[/quote]
No, there is no STU flash for the AccessPort. I asked Cobb about the possibility of releasing a STU flash using the same restrictions as their STX maps. Their response was that they didn't have any plans for a STU map and that they were too busy with other projects to devote time to develope the map. However they did offer to make a custom map, all I had to do is drive the car to Salt Lake City.
So, what I've been doing is loading the stock real-time map when I run events.

[/quote]
You must retain at least one converter and it has to be located within 6" downstream from the exit of the last stock converter. You should be ok with any catted downpipe.
Passing SMOG (I'm assuming you're talking about CARB smog tests) is a different matter. The aftermarket downpipe may pass a sniffer test, but if the tester is knows what to look for you won't pass visual inspection since you can't legally remove converters. However if the downpipe carries a CARB exemption you're golden (good luck finding one... :rolleyes: ). Emissions is another grey area of the rules since "emissions legality" vary from state to state.
This is another area of the rules that needs clarification. For instance, federal law prohibits the removal or modification of functioning catalytic converters. By removing the first converter, you're violating federal emissions regulations. But the rules specifically allows you to remove converters.

[/QUOTE]
All of these are good choices. The MX and Azenis are less expensive so they're better ;) . Gearing is going to be taller with the 245/45 Azenis. RPMs won't build as fast which should help on courses where you have to shift to third and then downshift back to second so you don't bog on corner exit. The big downside is the taller tire will hurt acceleration and there's a chance of falling out of boost on slower corners.

Thanks Henry, that was a big help! Guess I'll forgo the Teins with the EDFC then. Would have been nice not to have to strip the car apart to adjust the rears. But then, what IS the general consensus for the shocks on the STi? Tien, Cusco, SPT Pinks? And as this is for the 05 which has a bigger knuckle, the choices might be extremely limited.
As for the PDE plates, here is the link. Let me know if you think they are still legal:
[url]http://www.jscspeed.com/wrx/suspension/pde_camberplates.htm[/url]
As for the downpipe, if I go with one, I will get the cat in the dp. For a cat to work right (and perhaps help it to pass SMOG), it has to heat up, and if you car sits a bit before they test it, having the cat in the lower pipe would not heat up fast enough for the test. But in the dp it should. I have heard that the Prodrve dp has the heat shields on in the proper spots so that a *casual* visual inspection will look like it is stock. That was what I was thinking about - just you can't get theirs without buying the whole power pack.
As for the tires, that is a hard one. I have the MX's now in 225/45/17, and boy are the sidewalls SOFT compared to the Azenis! But the other things to think about are:
1) you make an excellent point about hitting the rev limiter too soon before a turn! That happened to me today about 3 times, and going into 3rd was not a help. So the stiffer sidewalls of the AZ and the longer gearing would be a good help
but
2) the 40 series would most definately have a bigger/wider tire patch and help a ton in the turns, would it not? Though that would mean either go with the more $$$ KD's, or the softer sidewalled MX's.
So hmmmmmm, gearing or grip???? :eek:

I wasn't up on the whole seat thing since I think the WRX seats are fine.... so it's 15 without hardware.

[/QUOTE]
Totally legal and not questionable. If the camber plates have a separate adjustment for castor, the rules specifically allow the adjustment of said castor using the plates. 'Camber plate' is a generic term that is thrown around for auto-x since there's a few different terms used by different manufacturers like 'top hat' or 'upper mounting bushing'.
The motion to disallow airbag equipped seats was thrown out. You are allowed to change to non-airbag seats.

Again... no clarification needed. This has been settled becuase there are some states that have no SMOG or whatnot that will check for a cat.. some still don't have inspections. So looking at lowest common denominator, what's legal in that state is legal, [I]per the SCCA rules[/I] to change. However.... if you live in a state with an inspection program, it's up to you to make sure you only put the part on before you auto-x and take it off after you're done. ;) (Nudge/nudge/wink/wink)
Rocky, I would look at the Tein RAs or new Flexes. The RAs are an inverted strut at 45mm wide and have a lower adjustment knob that is shielded from any damage. I love the suspension on the Wagon and it does very well. The Flex I think still has the adjustment on top in a standard upright strut design. You can run some pretty high spring rates for the street, yet the dampning is fantastic and smooth on the road over bumps or highway. Many people are starting to see they work well on the streets/highway and aren't as harsh as say yhr Konis with teh same springrates/valving. And to compare them to JICs or DMS... the Teins don't 'bounce' on the highway to give the driver that 'seasick' feeling after 30 min of driving.

soo, Alachua county in Florida doesn't have emissions testing or inspection. does that mean i can legally run in STX with a catless exhaust system?
just because they don't actually inspect your car doesn't mean it's legal right? I'm pretty sure it's federal law that you cannot run without a cat. doesn't matter whether the state actually checks for it or not.

:confused:
You obviously didn't read previous posts (or the SCCA Rulebook) very closely. STX rules allow you to replace all OE cats with a single high-flow cat. Where does it say you can go catless?
Something to keep in mind with SCCA rules - they MAY or MAY NOT be in alignment with federal or state regulations. KC's point was that if you build a car to ST rules, it may not be street legal where you happen to live.

I second the vote for the Tein Flex. I test drove Kiko Seibt's STi at Nationals and I was amazed how well dampened the car was considering the spring rates he runs. Heck, the stock STi suspension feels bouncy compared to the Flex. Granted, Kiko has the old model Flex but I can't imagine the new one being worse.

And to compare them to JICs or DMS... the Teins don't 'bounce' on the highway to give the driver that 'seasick' feeling after 30 min of driving.
[/QUOTE]
I second the vote for the Tein Flex. I test drove Kiko Seibt's STi at Nationals and I was amazed how well dampened the car was considering the spring rates he runs. Heck, the stock STi suspension feels bouncy compared to the Flex. Granted, Kiko has the old model Flex but I can't imagine the new one being worse.

As far as the rear adjustment, there are two ways about it.
1) Leave the bolts off the bottom of the back seat vertical cushion. That way you can pull it up, unlatch and then pull away to adjust. Then latch again.
2) Do like Kiko did and superglue 6" of plastic vacuum tubing over the adjuster knob and stick that out through the gap between the cushion and body. You can still turn it just fine.

As far as the rest of the mods go, just go read a bunch of STX threads. Everything is the same, except we are still up in the air as to what the best spring rates are for the STI vs the WRX.

2) the 40 series would most definately have a bigger/wider tire patch and help a ton in the turns, would it not? Though that would mean either go with the more $$$ KD's, or the softer sidewalled MX's.
[/QUOTE]
The aspect ratio does not have anything to do with the width of the tire. It only tells you how tall the sidewall is. A 40 series tire has a sidewall height that's 40% of the tread width, a 45 series tire means the sidewall height is 45% of the tread height. The Azeins tend to be wider than their published width. For instance the 205 Azeins are visibly wider when compared to another 205 tire on the same width wheel.
The MX is a very good tire but the Azeins is better. As long as you're aware of the disadvantages of both tires and plan for it. The grip on the Azeins goes away noticeably when they get overheated and they're heavy compared with other tires of the same size. The MX tolerates heat better, actually they need heat in them before they get grippy. The downside is a full tread MX has a lot of squirm, so you really need to shave them to get good grip.
It all depends on your driving style and your prefrence. For me, I didn't want to take the gearing hit with the taller 245/45 Azeins. I was willing to put up with the shortcomings of the MX. Now if the Azeins was available in 245/40, I'd be all over it.

Some people look at it as an "advantage" in gearing on an STi. You don't have to shift into 3rd as much with the 245/45/17 Azenis.

-Tom[/QUOTE]
Not that it would make that much of a difference...
40 series "would be" 24.7" and comes up to about 57.1 top for 2nds gear.
45 series is 25.6" and comes up to about 59.2 top for 2nds gear.
This is a definite grey area here and as 2 mph are not a big deal (as you will most likely have to go to 3rd with either tire choice. I'd argue that since you're going to 3rd anyway you might as well stick with the shorter gearing for the advantage on the slower 2nd gear turns.
Of course... this is a theoretical argument since there is no such available 40 series tire. So then I would start thinking... 45 series... can I stretch out the rev limiter a hair too? moving the rev limiter from 7200 (cut off if i recall) to to 7500 with the 45 series give us a 61.7 top speed in 2nd.
Personally if I was going to lengthen the top of 2nd... I 'd like it a little higher still for the STi...
Just my thoughts (related since I've been thinking about STU for next year)

Matt - We agree on all points ;)
I kind of went the "other way" on the WRX. It can use the extra gearing from a short tire, so the 245/35/17 is the tire to have. Because of the lower 2nd gear, I raised the rev limit 400 RPMs to compensate and get me back to where the 245/40/17 was.
Next year I hope to run the 315/35/17 with a 7500 or 7600 RPM limit and not have to worry about 3rd at all at Pros and only on the super long nationals courses.

Once their accesstuner software comes out anyone will be able to tune it and they will have alot of "cobb certified" tuners around the US, a dyno tune would cost about the same as a dynotune with any other engine management.

Well my plans are to start off the year on 275/40/17s on 17x10s all around. Then if we need the 315s first try them in the front only. The 315/35/17 is the same exact down to 0.1" height as the 275/40/17. I have no doubt in my mind that we will have no issues heating up 315s on the front of an STi. On the rear, I dunno.

Well, here is some news - Tein won't have anything out for the 05 (has larger knuckles so can't use 04 parts) until November, and even then its the SS (Super Streets). There is no time frame yet for the Flex or RA. Got that from Tein USA today in an E-Mail :( So looks like I might be a guinea pig to try out the SPT coilovers if I can get them (in another post on here somewhere - think have to get from Japan). Or a temp alternative is to install the PINK springs and PDE camber plates till Tein comes out with theirs. But which one? Flex or RA?
As for the tires, I am thinking of going for the BFG KD's in the 245/40/17 size. I had great luck with those on my old Z3 Coupe awhile ago. Sure I might loose some in a long straight, but might gain more in the turns with a larger tire patch for grip.
Oh, and as for a POD or CAI, I was told that K&N has one that works properly with our MAF. Anyone know for sure???

Hopefully things should be moving along with getting the car, and with the items I want on it. Might just become a guinea pig for those SPT coilovers for the 05. And hoping they can get me the BFG KD tires in 245/40/17. But then, what type of tire pressures should I use? Many say high in rear, others say super low in the rear for oversteer. With the 04 totally stock except for the Kumho MX tires, I was running about 48 fr / 32 rr. It seems to have been working ok, but my ears are always open to suggestions.
Oh, and in the last issue of Drive Performance, they pretty much came out and said the 05 DOES have the active yaw control on it! Perhaps for the typical Joe Schmoe driver (and many of my co-workers), they can't seem to understand the nice advantages/upgrades that were put into the 05 that I feel might make a difference in Solo.

Both are correct its more of a driver preference thing then a wright wrong. High or low rear pressures will make the car rotate more.

Yeah, the RA's are not double adjustable for valving. The Flex's are double adjustable for ride height though, which is handy. Suspension travel is not affected by ride height changes.
I have actually found it difficult to keep the ass end in line on my STi. Especially at nationals, during the practice, and first runs on first day. I ended up softening the rear bar fully, softer rear strus, some toe in and fairly even tires pressures front to rear to keep it more nuetral. Finally got it right on the second day. I was anticipating it to get tight once i hit concrete...but it didn't.

Ok, looks like my coilover choices will be either:
1) the STi ones from Japan which is a factory fit and thus made exactly for the car, and won't need rebuilding. Am told the springs are 345 fr / 275 rr
or
2) Cusco Zero2 R which has 7kg fr / 5kg rr springs. Of course one nice thing about the Cuscos (these are inverted too, by the way, as are the STi ones above), is that to adjust ride height, you can screw the strut down into the housing to keep the travel normal, instead of the normal lowering the spring and thus shortening the travel. This might prove to be more comfortable on the street during normal driving.
Consensus please??

Speaking specifically about the currently available tires, I don't think heat is nearly the issue that it was with the S03s. The S04s go off over 150 degrees, and are best between 110 and 140, IMO. The Kuhmos seem to need a little more heat to work, but still peak in the 140 range it seems. With a co-driver I think you'll be spraying down the tires after 2nd runs regardless.
This may be different next year when Hoosier makes their changes to keep up with the Kuhmo 710s. Who knows.

[QUOTE=ButtDyno]The season is pretty much over, isn't it? Why rush a decision like this? Wait until February and see what's out there.
Given tho, that a lot of well setup cars have higher rates in the rear, I dunno if I would get either of those.. you can always get custom springs for the Cuscos.

Ok, looks like I'll be going with the Cusco's then. But not sure about the springs. I think I will compromise and go with 8kg fr / 6kg rr. Then will be adding the Cobb swaybars.
Got the 05 Saturday, so all this is not a farce. Just waiting for all the items to come in (as well as breaking the car in). Will say, it feels waaaay better than the 04!!!!

Oooops, just started to read some posts, and it seems that the Cobb swaybars do NOT fit the 05 yet. Something about the revised steering rack. So now where to go???????

Just an FYI...
Before I installed the Cusco Zero2Rs on my 05 STi, I first installed a Cusco 21mm front a/r bar ( [I]probably should've chosen 22mm front since 05 STis come with 20mm front bars[/I] ) and a Cusco 22mm adjustable rear a/r bar. They fit perfect.
I am not sure what Cobb did so different in their design since Cusco bars fit both 04 and 05 models.
And I would definitely recommend the Zero2Rs to anyone. IIRC, I think Myles @ RaceCompEngineering has an extra set for 05 STis. Just let him know what spring rates you want and he'll hook ya up.

I do remember reading a thread about someone who went from a 20 to a 22mm bar (and already had coilovers) who commented on just how much better the car felt. I had to chime in and say I told you so... :lol:
He later admitted that he had listened, but just didn't believe me. :)

I'm surprised that Cusco already has a coilover that fits the 05s. The front hubs are different and coilovers that fit the 04 will not fit the 05s.

Ok, I should be getting the last set of 05 Cusco's from Myles shortly. His has the 8kg fr / 10kg rear springs. But I have seen some using the higher/stiffer springs on the rear??? Is that correct?
As for the swaybars, in the Cobb forums they are asking the ETA of their 05 bars, but no answer. On the SELGP website, they say "WILL NOT FIT 05" under the Cobb bar page. So not sure???? But when the Cusco's come in, we will try a spare set of Cobb, Perrin, and Progressive bars to see what works.

Z3,
I wouldn't do higher springs in the rear unless it was mainly an autox car and then anything else is secondary. I also would only do that on a WRX, not an STi. :)

Well, today, and in the rain, was my first event with the new 05 STi - and I took 1st place!!!!!!!!!!!!!!
Now of course, I only had 3 cars in my class, but the E36 //M3 and SRT-4 were no slouches either! And I was off by around 1 second of Ken Motonishi's time in his STS Civic, would have been 4th in STS after Art Rinner in his SE-R, and beat all of STX. So not too bad considering that:
1) the BFG KD's only had 60 miles on them
2) the car just broke 500 miles, so was not taking it to the limiter or pushing it very hard
3) only mods (still waiting on the Cusco's = Myles???) were fr/rr Cobb swaybars, Stomung Cat-back, STi SS brake lines, Group N mounts, and the tires
4) because it was raining, I had the trunk still packed :)
I will say, the 05 is a night and day difference from the 04! When I went into my very first turn with it, I almost hit the apex pylon with my driver's door because I took the turn expecting my usual understeer, but instead the car tucked in so unexpectedly quick! WOW!!!!! And its stayed tight all the way through that turn, and just about EVERY turn. As a matter of fact, I found that even with the Schoth harness, the higher g-forces showed the stock seat now became a limiting issue (Sparco Monza now on order!!!). And the slaloms? Holy moly this 05 went through them like a Corvair pivoting perfectly!! And the steering was soooooo freaking quick now, that I could not counter turn fast enough - was expecting the usual mush. And the tires? FORGET THE MX OR FALKENS!!!!!!!! These BFG's are amazing. Even at full tread, and the grease not off them yet, and in the rain. As for the DCCD? In the 04, I used the run full rear. But in this 05 the auto was right on. And the stocl struts & springs felt nice and tight. Wonder if they did change those too from the 04, learning their lesson??? Makes me wonder if I really would nead the Cuscos? Sometime too much . . . . . . is TOO much???
All in all, this was the best money I spent! This is THE best car I ever owned (though miss my old Lotus Euorpas hehehe). And since my Father died Aug 19th (Mother in 2002, why I missed the PRO Solo in SD that year), that is why I could get it. And this was the first time I felt happy since he passed away. This one is for you DAD!!!!!
