What kind of problems might I have running a wheel spacer that wide?

The wheels would be relying strictly on the lugs for locating.

Or I wonder if I could get a spacer built that has a hub nub that sticks out to act as a wheel pilot.



BTW not sure where this topic would go...

With the Prospeed brake kit, a wide spacer, nearing 1/2", is required.

I changed the wheel studs to ARP's ($11 from Jegs) and have had no problems.

Without the hubcentric locator, I have to be careful snugging up the wheel, making sure it gets properly seated.

Well then that should work OK. Since I know your stuff has been on track I'm sure an autox enviroment will be OK too.

Now all I need are 1/2" spacers, small flares, 335's and a TnT day.

Oh yeah, and money too.

You can roll the lip up with a ball bat for more clearance. I've also heard the fender itself can be streched out quite aways without using add-on fender flares. You just have to get the right body shop to do it. Another thing that may help to get more clearance is a bit of negative camber as discused in another thread in the suspension section. The hypotnuse of a triangle is longer than one of it's sides.

Yeah I may go W/ the beating the piss out of the rear quarters and then having it smoothed out method.
I'll have to shop around for a body shop.
Just don't want to spend alot of money.



The negative camber is out. #1 it's not legal in ESP. #2 losing a T2R because of spline mis-alignment doesn't sound like much fun to me, and it definately wouldn't go over well W/the wife. Both in terms of driving it, and in spending more money.

#3 when you list things like this it kinda seems smart ass-ish even if it's not supposed to. It's not.

Are you planning 335's all around, or just in back?

335's are pretty big . . . another option would be mini tubs and setting the wheels farther in instead of farther out.

335 and low budget don't seem to go together. I would think smaller tires kept fresh (replaced more often) would work just as well.

Now if you can keep 335s relaced often that's even better, but ouch!

No just the rear.
For a few reasons. #1 I'm using first gear alot more than I used to. 3.06X3.42=alot of torque.
So the extra tread width will help.
#2 Pro Solo's. Folks who haven't done one don't realize how fun this can be.
And the extra width along with sidewall flex will help the launch.
#3 Extra sidewall flex from being mounted on an 11" wheel. Will help the launch, help put power down on course, and have a feeling the rear will be a bit more predictable.

My light wheel purchase includes buying a set of 18x12's for the new V710 315/18's. And then later buy another set of 17x11's for the rear W/335/17's

Temps are not a concern in back for obvious reasons
Up front ANY thing over a 315 is too big. I'm gonna build some of the relective blankets to keep em'warm.

That's the best solution if I were rules exempt. But I gotta work withen ESP rules.

That's one reason why, even independant of tire temps, I wouldn't go to a 335 tire on an autox car. Just to darn wide. These cars are about as wide as anything out there as it is. I don't think in the back the effects are as detrimental, but up front I don't think I would go much wider than I am now. Except when I put 12" wheels up front, which I may still rule out because of the added out-board width.

And I thought you didn't want to spend much money...

Even in a Pro Solo I would think a 335 would still be difficult to warm up. It's usually too long in between runs. The 315's are tough at certain times of the year. We had a cloudy autocross last Sunday and mine took several runs just to get where they needed to be. But hey... it's your money!!!

Money spent is all relative isn't it?
Actually to TnT the setup I care not to spend a bunch of cash.

In a Pro I think 335's would be NO problem. Remember you get a "burnout box". Put it this way..With Pat co-driving my car, the 315's were SMOKING hot. And we even sprayed them down at one point, ala' Falken AZENIS.

And I think those of us W/315's who don't always have a co-driver (like local events) NEED a set of the reflective tire warmers. I admit that some days they are tough to get warm.

Put it this way 65 degrees plus W/BLANKETS and I am willing to bet big money we're faster on 315's. Below that and it depends. Based on tests I have seen, I think that except in extreme instances the 315 is faster every time.
