bought a used set of CCWs a couple months ago that were from a 2002 Z06 and I believe that was the original purchaser. The specs I was given by the seller were 19x10.5 et67 with a 295/30/19. According to online calculators, they should have virtually identical "poke" as an OEM Z06 wheel, which I had on the car before these. Everything sounded perfect, but after installing them yesterday, the fronts poke out an inch past the fender. It's not really apparent from most angles, but dead on from the front, it's a little too much for me. I have a picture of them mounted on the Z06 and they don't appear to poke out, but it's not the best angle either. The old for sale ad doesn't mention flared front fenders and the pictures I have don't show flared fronts. What gives? I'm starting to think there's something wrong with my car lol.

So besides trying to confirm specs with CCW directly, which still won't fix the issue, I'm thinking adding a little more negative camber (up to -1.2, I'm not sure what my current specs are but it's a standard non-Z06 alignment) will help. I don't imagine that would 100% solve the issue, so the next step is swapping the 295/30/19 for a 275/35 (which would be 0.5 inch taller...) or even 265. That should get it within a half inch alone.

Just trying to confirm I'm on the right track or if anyone has any other ideas I'm not considering. I plan to lower it soon by removing the front bolts. Yes, I know it may affect ride quality, but it's not my DD and I can always put them back if needed.

If you came in here, but can't help, the least I can do is give you some eye candy

 

I know R888s are wider than they advertise. 295 is more like 315 in reality the way they bulb out.

Is the edge of the wheel outside the fender or is it just the tire perhaps?

 

295 up front sounds like your problem to me. R888's indeed run wider than advertised.

 

As far as I know, these R888s were already on the car in the picture from the previous owner where they don't appear to poke out. The tire is virtually square with the lip of the wheel. If anything, the lip protrudes out slight further from the tire by about 1mm. I have R888s on my Z06 wheels as well. There is a slight bulge on the 305 on the rear Z06 wheel. I really don't think the tire is the problem. I know/hope a more narrow tire will help though. Any other ideas?

 

Are you comparing to an OEM Z06 rear wheel on the front? If anything, your 19x10.5 et67 will set further in the fender than an OEM 18x10.5 et58 by 9mm.

An OEM 18x10.5 on the front of my car pokes by about an inch, with -2.5* camber and 315/30-18. Are you sure about the offset on the CCW?



(full disclosure, this is a replica C5Z wheel not OEM, but it is 18x10.5 et58, same specs as OEM)
