wheel & tires sizes
My 99 coupe is lowered on stock bolts and I was wondering if I could run a 18" and 19" wheel set up. If so what width on the wheels and what size tires. dont want any rubbing issues.
Thank You

Yes, you can run an 18/19 setup. Typical wheel widths will be 9.5-10" front, and 10.5-11.5" rear. However, I'd suggest that you approach this from the opposite direction, and decide what tires you want to run, then get wheels to fit. Typical tire sizes will be 295/30 or 305/30, fronts 275/35 or 285/35. Don't forget you can also use the runflats that come on the C6.
These are just some guidelines; I'm sure they're not all-inclusive.

I am getting 18x9.5 front and 19x11 rear wheels with 245/40/18 and 285/35/19 Goodyear F1 Supercar EMT's (C6 Z51 tires). I picked out the tire sizes and matched the rims to them (with the guidance of John at CCW.
You can fit the 275/305 setup in non-runflats.

Russ, the specific sidewall profile betweeen front and rear tires is irrelevant, although it obviously impacts the tire measurements which are at issue. The general concern is that the circumference (aka rolling diameter) of the rear tire be greater than that of the front tire, so as to avoid AH problems. A 275/35-18 tire has approx. an 80.4" circumference; the 305/30-19 has approx. an 82.3" circumference.

Iron Chef,
Whether a tire protrudes past the fender lip depends not only on the width of the wheel/tire combination, but also the offset of the wheel. So its impossible to say unless one knows the specifics, or alternatively you see what other people are running and how their setup looks to you. I can tell you that with my Z06 setup (OEM wheels and OEM tire sizes) on my coupe, the rears do not stick out past the top of the fender lip, and the fronts stick out maybe an 1/8" or so.
I've heard it said (w/o any verification) that the various production tolerances on these cars are such that one will find some variation of this wheel/fender relationship from car to car.

chuck1026,
I don't have any pics at the moment, but in any event perhaps I wasn't clear as to my setup, which is not unique by any means. I have the OEM C5 Z06 wheels on my '01 coupe. The wheels are 17x9.5" fr and 18x10.5" rr, with Toyo Proxies T1-S tires, 265/40-17 and 295/35-18 respectively. I'm sure the offset specs are published here somewhere.
