I have 4 sets of stock rims and use all the 18's for track setup except one set (17/18) for street tires.

That means I have 6 17" rims sitting in my side yard doing nothing.

Here is what I was thinking, why not put my street tires on 17's all around and free up one more pair of 18's for track use.

Tire size could still be staggered (or not).

The only down side is they are 9.5 wide so might be a little bulgey with some tire sizes, but all I do is drive around town a little on the street tires.

Stock calipers would fit fine all over & offset in the rear adjusted with spacers on my (long) arp studs.

Am I missing something here or does it sound ok?

Put them on CL. There's got to be someone with an older F-body who'd love to have them.

I widened 17x9.5 to 17x11.5 to run 335s on the rear on my C6. Check with Eric Vaughn in Monrovia, CA or Weldcraft in MI.

Pics and cost?

dbratten

Mine were done by Weldcraft over four years ago so there's a good chance it costs more now but they were $200 ea. plus shipping.








I started with O.E. Wheels from forum sponsor JW Motoring.

Many things determine the fit so plan carefully.

I run 18's all around at the track and 17's all around on the street. I've never had an issue with it. I do turn off traction control every time I get in the car rain or shine but I don't think that matters much either.

I like it cause I can run cheaper Nitto 555 275's all around for the street.

FASTFATBOY

Those are 18 or 19 correct?

Give 'em to me, that's what my CMC car runs.

The widened wheels are 17 x 11.5. I run 18 x 10.5 on the front.

Same here but I use the 17s when I run on track in the rain as well. Using Continental ExtremeContact DW. No issues with traction control, ABS, etc. with the 17s all around.

I have run 17 on all 4 on street and track. Never an issue. Square, staggered, wide and narrow - it is all good.

froggy47

Yeah that's what I was thinking.

Thanks all!

I have a square 17" setup I run at the track, and I have to run in Comp mode or all-off. Otherwise the system goes nuts thinking the rear wheels are spinning too fast.

This is in my 2002 Coupe (not sure how that compares to a C5Z).

What model year? They fit without a mini tub?

dbratten

Base 2006 with no tub. I have COs which control droop better than stock as the rim to upper a-arm clearance is about 1/8" and sidewall clearance on the inside is 1/2". Rims work out to a 79mm offset which use no spacers.

Nice fit!

Any rub on the inner fender liner? Just a little?

dbratten

No, they clear with the Kumho 710s. The front rubs toward full lock with 18 x 10.5 and 305 x 30s.

froggy47

C5 is less room under the fender, I guess. Most I can get under the front (lowered) is 295 on 18# and a 315 rear. The 335's stick out so I run really stiff & custom bump stops to miss the fender lip (crosses fingers).

Hi froggy!

Love watching your youtube videos. I learned a lot!!

Here's some pics of my

CCW Classics Race Ver.

17x10F
17x11R

315/35/17 All around Toyo R888

Some pics are lower than other due to lowered on stock bolts.(Thanks to Froggy)

front bulges out about an inch, but haven't had any rubbing/scrapping on the streets and canyon road with stock suspension w stock bolts all the way low.

Nice M3
