15in Wheels for Autocross?
�
�
Hello all-
Assuming they were available, fit over WRX brakes and didn't cost a fortune, would running 15in wheels for autocross be desirable? If so, what width would you run?
Thanks,
Mike

Yes, they are very lightweight. Rota makes some that work on stock WRX brakes.

:eek: Rota makes 15's that clear the WRX brakes? What are the dimensions? Need a wide tire for that.... 15 x 7 would be good, 15 x 7.5 would be better.

You won't be sorry!!!:D 15x as wide as possible. Screw the offset, and get those wideazz vintage ponycar tires on there!

Yeah, which 15" Rotas fit? I'd love a set but thought the only real options were either custom or some of the older Subaru 15s.
| jmott | 01-29-2004 02:43 PM |
what class are you going to run in?
if its STOCK, 15 inch wont be legal.
if its STX, 15 inch wont be ideal.
if its SM, 15 inch tires dont come wide enough to be competitive.

jmott-
thanks for the response. Let me tip my hand just a bit. I am investigating bringing a less expensive, 15in, gravel-rally wheel option for the WRX into the states. It's avail in correct offset and will clear the stock brakes. It's avail in 6.5 and 7in widths and comes in around 16lbs.
Is there or would there be any interest in a wheel like this for the cone-crusher crowd, or is there just no "fit" in any of the classes?
Thanks everyone.

A 15x7 would be nice for my RS, I run DSP locally and the gearing is supposedly better with a 15" wheel.
Who makes these wheels?

we looked into making a 15" but i think it was last year we deptermined that there's more market for a 17 x 8 wheel than would a 15" wheel for competetion w/ subys.
| LyveWRX | 01-29-2004 04:08 PM |
The rally guys (like me) would like a 15"x7, Thou we only need like 400 whls/year max for the whole country I'd think....
Definately not enough to cost out a casting die, or even the molds and patterns to do this in greensand/cosworth processs, dont even think about forging dies....
(the above are some guesses based on machining costs and some time in foundry work)
You'd only have two competitors I think thou.. Compomotives at ~$235 and RaceLine/Speedline at ~$250 (and maybe OZ Racing but I dont know anyone w/ those)

Nick-
As soon as I have something concrete, you can expect to see some appropriate vendor posts. In the meantime, the wheel company my partner and I are working with have a rich rally competition history, make RUGGED wheels and would be able to position ($$) these things well under those two companies you've mentioned.

Why not? The current crop of top STX tires have sidewall stiffness a plenty plus you gain some great gearing and weight advantages which should more than make up for a marginally taller sidewall.
I'm currently using 15x7 Kosei K1's (~$120/wheel) and 225/50/15's on my RS. I hope they'll fit over the WRX brakes so I can use them on the WRX I'll be picking up after this season.

Because you'll be running against cars with wheels .5"- 1" wider with .5" - 1" more tread width.
Plus the slection of competitive tires is really limited in 15".
Falken Azenis - 205/50 only
Kumho MX - 205/50 only
BFG KD - 205/50 or 225/50

There are a few other wider 15" tires out there. 15x7 is almost normal. I'd like to see a 15x8 wheel (or wider) and slap a set of 245 or 265's on them.
I've had really good luck with 225/45 and /50-15 tires. If we took advantage of a higher redline, we probably wouldn't even have a set of 16's.

I agree, I was thinking more about the MY98-01 RS's where you'd have trouble fitting anything much wider than 7" wheels and 225 rubber. For the WRX 15" would be nice if it fit over the brakes but as you pointed out the tire selection isn't there. The only 245 tires in 15" are the SP8000 (nice but not competative in ST) and a Hoosier which wouldn't be legal (but a lightweight 15x8 with those would be a nice SM or SP setup).

I've run 15s in the past on my 2.5RS and love the acceleration advantage of the smaller tires and lower weight. Plus 15" tires are typically cheaper than the 16" versions.
In the past, I've run on the 15x6 Legacy alloys (which will clear 2.5RS/Legacy GT brakes but not WRX brakes) but this season I've got a set of 15x7 Kosei K1s (which I doubt will clear the WRX brakes either) from TireRack (note: they were on closeout a couple months ago and you had to use the Impreza L to even get them to show up as the 2.5RS listing only showed 16" and larger sizes...they don't seem to list them now, though). They are +45mm offset but with the smaller diameter tires (225/50-15 Victoracers), rubbing shouldn't be an issue.
Also of note, however, is that 215/45-16 (available in the Azenis) is very close to a 225/50-15 in overall diameter so short 16" tires would still give you the acceleration advantage albeit without the cheaper tire pricing).
FYI: Eric Kremelmeyer (DSP 2.5RS) and Kevin Hoff (DS WRX) were both running 215/40-16 Hoosiers last year at the Petersburg ProSolo and both did very well in their respective classes. (I was at the back of the DSP pack on worn-out second-hand 225/50-16 Victoracers... :lol: )

Based on first-hand knowledge, no, the 15" Kosei K-1s won't fit WRX brakes. I tried them on my sister's WRX just for a data point.
I use 15x8" Volks with 225/50-15 Victoracers. Light, gearing advantage, cheaper than 16s, and I eat those silly 2.5RSs, WRXs, and STis for lunch. :lol:

Before I bought my Volks last year, I was split between the 245/40/17 Kuhmo MX and the 225/50/15 BFG KDs. I decided on the 17s simply because of resell value if I guessed wrong. I'm still not sure I made the right choice, but the KDs seem to be good only in certain conditions. At a dry, warm ProSolo, the 15" combo may be the way to go.
In any case, I'd only be interested in very lightweight 15x8s.

There is right around .5" height difference between the 225/45/15 and the 215/40/16. The widths are just about the same. Pricewise the 15's are cheaper, but depending on what class you're running and whether you have a set of 15x7 or 7.5s already could cause one to choose the 215/40/16 over the 225/45/15.
There are larger 15's available that would be a good fit for a 15x8 wheel. Everytime I chose our 15's over the 16's (using 225/45/15), I absolutely loved the way the car clawed out of the gate, corners and through slaloms. Braking into corners could be done a whole lot later or given up altogether. I could do without
the need to hit 3rd so quickly, but WTH....with another 5-700 rpm, I'd not need to hit it and still carry the same speed through sections where the 225/50/16 and 245/45/16's are just getting into the powerband.
Bottom line....15x8's would be a very profitable wheel if someone chose to make them available at decent prices. Rally folks would snap them up, as well as creative autocrossers, especially if they've got an RPM range to take advantage of them. Using RA gearing or other hybrids of Subaru gearing (auto diff ratios), one could scream through 1st and 2nd and run a typical course in 3rd as many SP cars do now with their 225/45/13s on 13x8s......

I just posted requesting more information on the wheels. Does anyone know if the clearance is different between the '02/'03 and the '04? I know they take different pads, so I wonder if the caliper clearance is also different.

Those Raceline wheels are pretty heavy. Built for strength not lightness.
IIRC there is no difference between MY02-03 and 04 wheel clearance but I don't know for sure. Someone please clarify if you know.
Thanks for the info on the K1's Pat. Saved me 10 minutes with a friends WRX. Guess I'll sell them off when I finally upgrade the RS.

Will they also clear 4 pots?
| Patrick Olsen | 01-31-2004 11:37 PM |
Nate, the K-1s [i]might[/i] clear 4-pots. They have pretty good spoke clearance, so I wouldn't think that would be a problem. I told Tony via email that the K-1s hit the WRX calipers on my sister's '02 WRX along the circumference of the wheel. As I recall the 4-pots don't extend out as far in the plane of the rotor, so maybe they would clear? It would be pretty damn tight, methinks.

I just now noticed that the Kosei K1 / 4-pot question never got answered on this thread. At least year's SEDIV in Laurens, I test fit a 15x7 +45mm Kosei K1 over one of Scooby South's 4-pots (back when he still had the EJ20-powered RS) and it just BARELY cleared. I can see why the taller USDM WRX setup doesn't clear these wheels as the 4-piston caliper has almost no clearance as it is. IIRC, caliper width vs spokes wasn't even an issue at all, only the height was really all that close.
So it does appear to fit, but it's VERY close.

After more seat time with bigger wheels and tires vs. 15x7 w/ 225-50-15 on them....I'm sticking (better) with the big wheels. We're stuck with a 6500rpm limit at the moment still and until we can rev at least 1000rpm more....will stay on the big wheels.
I think it'll take a custom wheel wider than 15x8" and a sky high rev limit to make it work.

Having the wide wheels made is not that difficult(or expensive). Finding good rubber to take advantage is. Roadrace compound Hoosiers are going to show the most promise. Full blown slicks if you wanna play in prepared or modified..... You're still gonna need to spin the sucker well past 7k to see any true benefit.
However, if you run on primarily small lots with more technical course layouts, the 15s will be closer to being on par with larger wheels. I would say 245 at the minimum for width to consider them. YMMV

So what are you running now, Jay?
I'm still running 15x8" TE-37s, now with 225/50-15 V710s. The Volks clear the WRX brakes (I upgraded to those a little while back), so I'm good to go there. My wheel wells are so tight that I can't see fitting anything any wider than the 225s I have now, so in my case I don't think there's anything to be gained by going with a 16" or 17" wheel. I'd love to fit a 245 on the car, but I just don't see it happening.

We're running 265-45-16 V710s on 16x9" wheels. The car is raised a little to minimize rubbing in the corners, but we have very-very little roll anyway. What we do have is massive inside rear wheelspin.....to be taken care of by Topeka.
I ran the 15s and 16s back to back at both small, technical regional stuff and the Toledo ProSolo. We were faster overall on the big wheels in both cases.

I ran the 15s and 16s back to back at both small, technical regional stuff and the Toledo ProSolo. We were faster overall on the big wheels in both cases.

Why Jay don't 285/30/18? Shorter and wider == better.

[QUOTE=Storm]However, if you run on primarily small lots with more technical course layouts, the 15s will be closer to being on par with larger wheels. I would say 245 at the minimum for width to consider them. YMMV
Jay Storm[/QUOTE]
I do...and this is exactly why I run 225/50-15s. On most of the local courses I don't even top out 2nd gear with the small ratio tires, so I am accelerating better on the entire course than RSs with taller tires. Launch in 1st, shift to 2nd and just drive. :)
Now when I get to bigger courses (like the SEDIV courses) that require 3rd gear, that smaller tire starts to bite me a bit, but 90% of the courses I run don't use 3rd, so the smaller tires are a better choice for me. Personally I'd run a 245/45-15 in a heartbeat if it were offered, but none of the DOT R-compounds seem to be available in that size (the only 245+ 15" R-compound I can find is a 255 R3S04, but it is so tall, you might as well just throw a 245/45-16 on instead).

Holy crap! That is shorter than stock! :eek: {drool} I'm pretty sure I'd need some fender mods to fit those, though (or ungodly spring rates and high ride heights like Storm and Zyxxy use). :lol:

Also, to any people that come and say "225/50/15s would dominate STX", a 245/35/17 is just a bit shorter ;) Why do you think I ran that size last year.

I have the same wheels as Jay for the new SM car, and the main reason for me was the cost of the wheel. We paid something like $1k for the set of wheels. When I priced out 18x9, 18x10s they were quite a bit more. In my case I'm using a 3.90 6MT with about a 7500 RPM redline so the gearing of the 265/45 or 275/45 isn't so bad. Shorter is better, but I don't like shifting. Air cutoff wheels take care of clearance issues...
I'm using 16x10 ones versus the 16x9s that Jay has. The 16x10 wheels weigh 13 lbs.

-Tom[/QUOTE]It came down to the short term and long term cost of that setup. I'd love to try the infamous [I]conebasher's[/I] wheels for an afternoon....but we're pretty happy with what we got now.
I do ask myself why I didn't write 18x9 or 18x10 in the dimensions block of the wheel order form when I'm checking out the competition.....The cost vs difference in performance became a hard decision to weigh out.

In the case of the Real Racing rims, they don't make them in sizes above 16", so that's easy. :) If they would have made them in 18x9/18x10 I probably would have gone that route.
Of course the cost on the Real rims is much higher now than it was before, they are about the same price in 16x10 per set now as a set of CCW 18x9/18x10 rims.

CCW == $1800/set. Cheap if you ask me for a set of custom wheels.

285/30R18 tires, on 18x10 CCW wheels:
[img]http://www.brennen.net/images/evo_two.jpg[/img]
Tom's right... $1800 for a set of CCWs is a pretty decent price for custom wheels. Although I think I paid something like $1860, which included the
black finish (and which added about 3 days to the delivery time).

.....and is about $700 more than what we paid. Plus the sets of tires themselves are going to be another couple hundred more per set. We had to make the decision.

$120 ea...bargain!
I called Todd at Frisby Performance Tire in IL he had them shipped to MI direct from CA in 2 days!

[QUOTE=Storm]After more seat time with bigger wheels and tires vs. 15x7 w/ 225-50-15 on them....I'm sticking (better) with the big wheels. We're stuck with a 6500rpm limit at the moment still and until we can rev at least 1000rpm more....will stay on the big wheels.
I think it'll take a custom wheel wider than 15x8" and a sky high rev limit to make it work.
Jay Storm[/QUOTE]
Send your ECU up to Yoshi in Canada. He'll solve your rev limit concerns and help you out some else were too. I know Steve ran an ECU from them before he went with something else. It wasn't a full 1k RPM raise though. I want to say it was 6800-6900 due to oiling limitations on the stock EJ25 N/A design for more sustained high g cornering.
I'd like to see some 16x8.5 -16x9 wheels for subaru's. Would be great for a 265/45 Kumho or 245/45 & 255/50 & 275/45 Hoosier.
Jay, where did you get those 16x9's at? PM me the info if you don't mind. I'd like to find a set for my car for SM next year.
I don't think the need is for lower gearing in the RS, just need more power & higher revlimit.
I know some wide 15's would be nice, but there isn't enough wide tires in that diameter. IMHO anything less than 245 isn't enough. Anything more than 275 is too much. But that is just my $0.02
Look forward to seeing your RS in DSP this year Jay... since Steve is being a tratior for nationals and running a BMW in STX.

Damn, now i'm all confussed. I had settled on a set of Kumho 710 size 225/50 x 15 on Team Dynamics 15 x 7 for next year for my Legacy but now I don't know what to run. Anything would be better then my 205/50 x 15 on stock rims with two seasons on them I guess.
Someone must have some data on this issue, width vs weight and rolling diameter etc. The great thing about my current setup is it only weighs 35lbs.

Get a set of 16x8" wheels
Run 245/45-16 all around or just in the front with 225/50-16 in the rear.
You'll be fine and happy on a local and perhaps even divisional level. Cheaper, easy to fit, easy to use.
Just my $0.02 Unless your going out to win nats, 245/225 is sufficent 90% of the time.
Depends on your region though.

More 16" selection both in wheels & tire size.
Wider sizes both wheels & tires.
Cheaper than 17" or 18" solutions.

He's going endurance racing on 15" tires (an upgrade from his 13" wheels) in an EA82 powered mid-80s Subaru that is coughing between 2-3 times the power of it's stock output. On a stock turbo.
Then he'll roll up to the autox and set FTD like he's been threatening us with for several months now. :)

I have a set of 15 x 6.5 5x100 42mm offset (I think) Flik Apex wheels. They are 14.7 lbs and look like TE37. They have some half used Azenis on them and are sprayed flat black with cheap paint. I had them on my mk3 GTI with spacers and the light weight was incredible - moreso than the same weight 17" wheels. I *think* they will fit Subaru as is. I'll sell them cheap!
