If so, any issues? I know they will stick out and don't look the best, but I want an inexpensive wheel to fit over my StopTech BBK and used Z06 wheels are plentiful on the forum.

What is the minimum height between top of tire to bottom of wheel well to prevent rubbing on hard corners? I'm running pFadt gen 1 coilovers and stock Z51 sway bars so I may be as to control body roll a bit.

Has anybody done this and what were the issues you may have encountered? Got any pics? What size Hoosier or Conties fit the stock Z06 rim?

I think they will stick way out. The C5Z 18's fit a base C6 pretty well, but sit way inward on a C6Z06. So conversely, I think the C6Z rims will stick out a few inches.

I knew they would stick out, I was just hoping that maybe somebody found a way to run them on a stock C6 safely.

Thanks for the insight.

C6Z06 wheels on a base C6 will stick way out in the back- that's a bad idea. Too much suspension compression and you'll crack the rear quarter panels.

With CCWs made to use Z06 tires on a base C6, the clearances are fairly close but no issues and that's with 9.5s or 10s in the front and 11s in the back. 12s or 13s will not work.

Thanks. There's a set of 18x10 and 19x12 locally for sale that I'm looking into. Why won't the 12" wide wheel work in the back? The set I'm considering came off a base C6. What will the 12" wide wheels hit or rub to make them not work?

Stock C6 Z06 offsets will not work on a base car with stock Z06 sizes. Period. The rear wheels will stick out a couple inches and if you compress the suspension, the tires will hit the tops of the wheelwells and crack the body. Search the forums for photographic proof, it's there.

If you're talking about a custom set of aftermarket wheels, it's possible that someone may make a set of 12" rear wheels that fit- but that's very, very close. My CCWs are 11" in the back and even with 305s, it's pretty close- with 325s, I think I'm right at the limit. You would need to have that extra inch of wheel inboard- I don't think there is enough wheelwell clearance to make that happen.

If you're local, test-fit the wheels before buying.

Yes they were CCW wheels that I'm looking at. The seller has them on his base C6 now. Doing a test fit is a great idea!

I would plan on putting Hoosiers or Continental slicks on them, most likely 285 front and 325 rear.

What would you say is the minimum clearance between wheel/tire in the rear? I would think 1/2" should do it to account for sidewall flex on corners?

cleanerPA

If they're CCWs made for a base C6, they're probably fine. I'll bet they're not 12s but rather 11s in the back, though.

You have to make sure that the tires do not stick out at all from the wheelwell. You need to make sure that at full compression, the tire cannot contact the tops of the wheelwells, or you'll end up with cracked quarters. Under compression, the camber will go negative, so you should see the tire tuck into the wheelwell, but you need to make sure there is enough clearance from the outer sidewall to the inner wheelwell.

I tried C6Z06 wheels and tires on my 05 C6. At VIR the rear tires hit the fenders on acceleration out of Oak Tree. The smoke was noiticible enough that I got black flagged. Had to put Z06 fenders on.

taken-
Those CCWs from the shop in FL will be fine- I'll bet they don't know the actual size and that they're 11s in the rear. Regardless, those wheels are built specifically for use on a base C6 and will work fine- that's the same setup that I have, almost to a "T"- I have the same C140s in a different finish.

Thanks for the info. That shop is my current tuner and I've been looking for an excuse to head that way for a few weeks to clean up some tuning issues.

Got any pics of those wheels mounted so I can see how the outside edge sits relative to the wheel well? I think I may have to lift the car nip another 1/2" or so to ensure the wheel doesn't rub on hard corners.

Way width are you running on your rims? If 325's, what kind or room do you have between the rear wheel and inner fender liner?

cleanerPA

Sorry, can't do it on short notice.

I'll say this- raising the ride height will do nothing to fix your problem- suspension compression depends on spring rate, nothing else (with all other factors being equal such as shock length, etc). You can raise the ride height and still hit the quarters unless you put in taller bump stops.

I'm running 305/30R19s in the back, but the wheels are designed to work with a 325/30R19 (stock Z06 sizes).

Here's a pic of my old car with CCW 18x10 and 19x11, running stock Z06 Goodyear tires (275 front, 325 rear)
Only had rubbing on the rear wheel well to the inside and my car was lowered.

taken19

Great pic, that's exactly what I needed to see. Did you have coil overs or was it lowered on stock bolts? I think coilovers can solve the inner wheel well interference problem.

1BDRSK

That was just lowered on stock bolts. It would only slightly rub on the inner fender liner....nothing to big to worry about....sorry hurry and grab those wheels, they're a great deal!
