I'm fairly certain these sizes will work, but has anyone used this exact setup on a lowered C7Z?? I've gone through a very long thread about them but it looked like everyone was running stock ride height

have factory wheels and would be going with 295/30/19 and 325/30/20

Any issues? My fronts run the inner fender lining now when close to full lock at low speeds, i dont think the extra 10mm will be much of a difference



or... has anyone run R888R's in rear with Michelin fronts? I dont love the idea of non matching tires, but i really need the traction and just got done putting some money in to other things so anywhere i could save would be good

Youll have stability issues at higher speeds if you mix run flats up front with non run flats in the back. I didn't believe it until imy car started wagging its tail at 120+. I then went with R888Rs on all 4 corners and it was very stable again.

My fronts are lowered by about 10mm, and my rears are still stock. It measures 693mm front, and 725mm rear. I've been using 315/30/18F 345/30/19R tires with no issues besides minor rubbing on a few places (R7, R888R, and RR). Tires are very close to the fenders, though, and especially at the rear, some of the sticky road debris (like rubber pieces at the track) were lodged into, and damaged the liner a few times. In any case, nothing too problematic.

I have a z06 z07 with drop spindles and needed more traction as I have 711 whp. Compared to my buddies stock z06 z07, my car is about 1.5 to 1.8" lower front and rear. I went with R888R's in 285/35/19 front and 325/30/20 rear. No issues at all on the rear and definitely better traction over the sport cups. However the fronts do rub on full lock and when cornering hard at the track. Check the height of the 30 series tire vs the 35. I'd think you would be ok.
