Rear Drag Package for Z51
So I've been looking at getting a rear set of wheels and tires that will allow my car to actually get a good shot off the line because currently the 19" Invos on the car suck.
I wanna drop down to a 18" rear wheel dia. to get some more meat in the rear however I don;t wanna have to blow $2k on custom wheels. I know the 18x10.5 +58 wheels will poke out of the fender by almost 1.5in, but I was wondering if anyone has gone to the 18x9.5+57 and stayed with a 285/40R18. I've worked with the online offset calculators that show it would poke .6" more but is that too much on a vette?

9.5 x 17 GM factory wheels will fit and hundreds of Vettes use them. The most popular are C5 Z06 fronts, since they are the lightest of the 4 styles. The others in order of increasing weight at about 1# per style. are C4 A-molds, C4 sawblades, and C4 salad spinners.
Drag radial tire choices in the most popular 275/40/17 size from lightest to heaviest are: Hoosier, MT, M&H, and Nitto.

Depends on the track, but ET street R would give you better tracion, c5z fronts 17 x 9.5, would be the way to go. I personally run 305 nt05r on 19" for the street as I don't get on it much and full slick at the track, for best traction, the tires are cheaper and last longer.
