Prod GT RallyX tire recs?? part 1

wrrrx 08-17-2003 11:36 PM

Prod GT RallyX tire recs??
Any of you folks out there that participate in RallyCross, or even ClubRally, in Production GT, have any tire recommendations?
Pleeeease?
Accdg the the rulebook "Only all weather/summer tires allowed: NO Rally or aggressive all-season* tires allowed"
"Aggressive all-season tires are defined as a tire with tread gaps greater than .225 inches that run horizontal to the tread."

So- Jamie, Glenn, etc? Anybody have any input??

I did okay last year on those crappy RE92's, so mebbe I should just look at something along those lines, but I'm [I]hoping[/I] there's a better choice!

Only caveat- they have to be available in 17"... :D
Yes- time to see how stiff the stock STi suspension really is!!
WhooHOOoOOOO! :disco:

thanks for any help,

I can't say I advocate using your STi for rallycross, though, if your playing those cards...

Continetal ContiExtremes are mounted on my everyday wheels and for an event in New Hampshire I left them on because of so much rain and mud. They worked very well for that and they seem to do well in the Pine Barrens. (Very loose sandy surface). It is a good all season performance tire for the street as well. Dunlop SPs are mounted on a set of steel wheels I have, I've used them at rallyx and they have worked well enough, though with a lower HP car like my L, less traction can help keep the motor reving.

My suggestion, if your worried about snow-tire rules (something that's never been an issure for me) try the ContiExtremes and take it easy your first time out man!
thechickencow 08-18-2003 12:19 AM

The way classes are run around here Production GT would be a class that has Rally tires allowed. We use the ProRally classes in general, then if your car isn't prepped or on street tires you run a class based on number of wheels driven and displacement.

Chickencow (?), out here in "Orey-gone" we limit the Production classes to non-aggressive tires, so no-go on rally tires (which are mighty tricky to find in 17", in any case). They're serious about the no winter tires, etc.. too, so it's all-seasons for me!
I actually support the rule, as the other rules (we follow ClubRally Prod GT specs for the most part), allow a [B]lot[/B] of, ah.. "upgrades"- so the tires are the only thing seperating some Open Class cars from Prod GT's.

Kitsune- Thanks, the ContiExtremes look pretty good! It looks like the treadblock gap might be >.225 (why not .25, I wonder?), but they're not really [I]horizontal to the tread[/I] are they??
Hmmmmm....
Heh. Minor technicality?
Mebbe. Mebbe not. (prolly depends on how I do... :cool: )

Oh, another thing- it's not my first time out- it's the STi's first time out! :p
And hey, if I can't RallyX an STi occasionally, well, there is no God! :confused:


Thanks for the input,
keep it coming!

Tires are open out here so on soft surfaces I run Blizzaks (4 wins), Medium surfaces I run BFG KDWS (2 wins, 4 seconds) and on hard surfaces I ran Kuhmo MX (no wins:( ). I have seen Azenis win once :eek: and Re-92's take a couple.

I looked at a Conti Extreme Contact on Friday and thought about replacing my KDWS with them. Tread depth is a little shallow at 10/32. They have a very interesting pattern. I liked the KDWS alot and drove them on the street as well. About 30k miles plus 15 RallyCrosses and a drivers school before they started to fade. I would probably choose between these two.

We had an Sti run yesterday on 17" wheels, but it was a very smooth surface.
Subie Gal 08-18-2003 12:28 PM

blizzaks would be a snow tire.. thus open class :)

i have run my dunlop sp5000's with success ;)
in pgt...


but prefer to use rally tires..
the grip is phenomenal in comparison
and i prefer to run open class anyway :)

cheers n have fun

Thats a whole different ball game then. I think they set them up in our area so anybody that has a rally car can come and use their normal class.

I end up running PGT because of the rally tires, even though I don't have a cage.

As for the all seasons, I honestly would think most will be roughly the same as any other. I had success with RE92s in rallyx, but I don't think I'd go out of my way to buy those if I were you.

Does the STi count as PGT class? If so, then I'm gonna leave my CAI on my RS, and run in PGT, and if they don't like it, I'm gonna make a stink. PGT allows small mods, and a CAI is a pretty small mod, IMHO. If my intake makes me run against ClubRally cars, while an STi gets to run against stock Outbacks, that just ain't right.

My mods: CAI, K&N, axle-back muffler.
HondaH8er 08-18-2003 12:45 PM

Production GT (PGT): 2WD or 4WD with adjusted engine displacement over 2650cc as prescribed by SCCA ProRally Production GT guidelines. Very limited mods over Stock.
Only all weather/summer tires allowed: NO Rally or aggressive all-season* tires allowed.


Open: 4WD - almost anything goes. Engine modifications allowed. No turbo inlet restrictors required.
Max Adjusted Displacement of 5100cc.
Rally and aggressive* all-season tires allowed.


Adjusted Engine Displacement/Engine Size Multipliers: This may be kind of confusing, so feel free to ask the Event Steward or a fellow competitor at the event, but please don't bother the Tech Inspectors; they have too little time to answer everyone's questions. So, to figure out your "adjusted engine displacement" take your actual displacement and use the corresponding multiplier for any equipment or engine type that may apply to you. Equipment:
Multiplier to Original Displacement:

Rotary Engine
1.8 X

Turbo/Supercharger
1.7 X

4WD Vehicles (P & PGT only)
1.3 X

Pushrod/Diesel Engines
0.8 X

3 Valves/Cylinder
1.1 X

4(or more) Valves/Cylinder
1.2 X

Variable Valve Timing
1.1 X


EX: A 4cyl 2000cc 16 Valve engine with Variable Valve Timing would have have an adjusted displacement of: 2640cc. How did we come up with that?

(1.2 multiplier for 4 valves/cyl) X (1.1 multiplier for VVT) X Actual Displacement of 2000cc = 2640cc Adjusted Displacement


STi has an adjusted displacement of 5100, max for Open class.

rallyx rules differ region to region.

in our region... rally tires are not permitted unless you run in open class. period. (for all AWD cars)

and yes.. STi = PGT... even in clubrally... :) fun huh?


and yes.. CAI and K&N = open class.
no way is that PGT legal... [i]in our region[/i]

HondaH8er 08-18-2003 03:25 PM

Freakin' weak.:rolleyes: Got to drop my power to run against STi's, or keep the intake and get whumped by rally cars. It's a PITA, but I'll take the intake of so I can at least have a chance in PGT. What about the K&N, can I at least leave that in there? Or can I put the paper filter back in and leave the intake on? Doubt it on either one:mad: What counts as "very limited mods over stock", anyways? Are they just talking about stickers and chrome? Seems that any engine mod you do bumps you out of PGT anymore.
Subie Gal 08-18-2003 05:10 PM

engine / intake mods = no pgt

limited mods include:

suspension
brake lines/pads - but not calipers/rotors

see the entire rulebook at: [url]www.scca.org[/url]

what you fretting about? ;)

1 - the intake and K&N are not adding much HP to your car

2 - the course is so short and tight..
you should be able to beat/run/with an sti or wrx hands down....

in our rallyx's... really, nobody has a chance to get into their power band.... thus it's mainly driver skill and keeping up what little speed you have into and through the corners...

have fun
Jamie
HondaH8er 08-18-2003 07:52 PM

And that's my point. Because of my minimal mods, I would have to run in Open, where a ClubRally or ProRally car will trounce me because it has a stiffer chassis, rally tires, and tuned suspenstion, which will give it a big advantage over me in the tight stuff with my stock suspension and rear swaybar. Guess I'm just going to have to take the time to yank all that stuff off my car just so I can run with other cars that still have stock suspension but lots more power than me. Not gonna do me any good to argue, although I can't find any rallycross rulebook on [url]www.scca.com[/url] . In fact, I can't really find anything related to rallycross on thier site.
rupertberr 08-18-2003 09:22 PM

Man, Oregon is no fun! Come RallyCross in the Rockies. We have found that horsepower and tires aren't important .;)

We have five classes based on Club Rally. Tires must resemble rubber. Intakes are fine, they make no difference except they suck up more dirt (and water RIP Honda Civic). Suspension and exhaust are open in Production Classes. A couple events ago the fastest and slowest class winners were seperated by 1.5 seconds. An Sti ran in PGT yesterday and was 3 seconds a run slower then my WRX Wagon, I was 3 seconds slower then the winner. Once in Utah I was only a fraction faster then a $50 first generation Honda Civic.:eek: We had one ProRally Group N EVO on Rally tires shared by three drivers a couple weeks ago. Cars that were faster then them included a stock RS2.5 on Azenis(Hi Keith!), Honda Civic, WRX on Re 92's and the real bad boy: 80 hp Isuzu I-Mark!:lol: The G2 I-Mark is consistantly fastest of all the cars that run with us!

So basically don't stress and have fun. Just run in Open. It's less work. Or come here and run in PGT, we're faster then Open!
RRR-K2 08-18-2003 11:17 PM

Just have fun!
Tires can make a difference, especially rally tires. But what makes the biggest difference in a RallyCross is the driver, PERIOD!

At first, concentrate on learning how to drive what you have to the best of your abilities. Then, once you decide to really get competitive ;) , worry about what class you're in.

As Jamie said, most cars don't have many chances to really get into their powerbands. In fact, we had this discussion at one of the New England RallyCrosses last year. Most of us in the discussion basically agreed that a RS has about the best balance of power and response for RallyCrossing.

Remember, the main point of RallyCrossing is for people to learn how to better drive their vehicles. Beating up on RS's, WRX's, and ProRally cars with your 12 year old, 180,000+ mile, 2.2l, daily-driver Legacy is just a side bonus :devil:

Uh yeah. Back to [I]tires[/I] ...
thanks to everybody who replied on topic. :)
Anybody else w/ anything useful?

HondaH8er- the online rulebook is under Performance Rally at scca.org.
In the pdf file, the classifications are under ClubRally, since we use those for RallyCross.
Stock cars= production classes, pretty straightforward.

Feel like I just got beat up on in O.T...:huh:
Where's the love?

rupertberr 08-19-2003 10:08 AM

Oops...sorry.:p

Just noticed KDWS don't come in 225/45/17. Too bad because they have a very hard sidewall that helps keep them on the rim during that sideways stuff.

The ContiExtreme seems very interesting and the price is good $106 for 225/45/17 and $75 for 205/55/16. Tread pattern looks like a street version rally tire.

The STi that ran on Sunday used ContiPremier and finished mid pack. I don't think those tires were aggressive enough.
BlackfeetVI 08-19-2003 10:46 AM

I use the 205/55-16 ContiExtremeContacts as both my daily driving tires and my rallyx tires. At the Corcoran Rallyx last weekend I noticed a distinct difference in my grip levels vs my old RE92s (obviously :D ). They're very progressive, and wear well. We were running on a combination of hardpack dirt, loose gravel and wet tarmac and they were awesome. For the price and wear rating they're hard to beat. Good luck!
rob 08-19-2003 01:09 PM

Oh lord,

you are not running at hood river with the STi are you? Why not be a good sport and put slicks on to make it fair for the rest of us :)

All gravel?? I did not know that. Did we have one there last year? If so, any chance you have pics Jamie (I guess I could just look on your site)? I can wash off mud, but chips are a bit harder to deal with. Now I'm worried :)

Yeah, whatever buddy. I see you right behind me in points...:lol:

I really think that it is your responsibility as an STi owner to protect it from all the rock chips you can. You didn't want to have to be in HR at 8am on Sunday anyway, right?

That's OK, I'll roll my ride:p Now I just gotta decide if I want to run in PGT or Open. PGT means having to take out the CAI (and the horn, since it sits where the stock intake would go) and disconnect the ProECM. But I'm lazy, so I may just run in Open. but I would like a crack at beating an STi:devil:
rallysquirrel 09-03-2003 12:08 AM

back in the day in Colorado....
Rupertberr and I used to rallyX together (until I moved to CT). I used to have a 97 outback with wrx wheels and tires, and I'd do just as well as the guys with "better tires". I'd have to say the RE92's aren't bad in the dirt; only snow:(

Hey I got 2nd place in PGT for the year with RE92's
Rupert beat me with KDWS ;)
grumbly 09-04-2003 04:19 PM

For PGT new RE-92s are actually a really good tire. I ran them all last year on my wagon and was 5 in points at the end of the season. This year Im running a different tire and no.. im not going to tell you what it is. :p

[offtopic]
Did they bother to give out last years awards yet? I didn�t make it to the last rally-x and of course no one contacted me about picking mine up.

[B]AAAAAAAAAAAARGHHH!!![/B]
GOD, I'm frickin' P I S S E D !!!:furious:

Hood River RallyX results are in.
They bumped me into OPEN.

[I]Without telling me.[/I]
(In fact, Tech told me I was "good for PGT").
Never mind that I actually meet the reqm'ts for PGT, apparently Oregon Rally Group knows better than Nat'l SCCA.

Now I am *totally* screwed over.
I have 4 almost-new all-season tires (one Rally-X and ~150 miles on them) that will be near-useless in Open Class, :rolleyes: and worst of all- for the season, I have 15 points in Prod GT and THREE points in Open.
That leaves... oh, [I]zero[/I] percent chance of winning ANYthing.

Here I am, trying to do the right thing, planning some mods- "lessee, gotta keep a cat, can't change intake, blah blah blah")
Ha.

Oh- and just 8 days before the next RallyX.
Thanks guys- thanks a LOT.

I'm just *%&#@&* LIVID!

Apparently, I'm just not supposed to run the STi.:confused:
AAAAAAAAARERRGHH!
