What smaller wheel size would work on the C8? I’m thinking 245/40/18 and 305/35/19. Any problems with this in terms of caliper clearance or traction management issues?
The brakes are smaller than the the C7 wide body cars that run 18 inch wheels on the track so I'm sure they'll fit. How sensitive the car is to overall diameter changes of the tires, nobody knows. Sounds like the sizes you reference should be very close to stock diameters.
Do you know the new wheel bolts offsets are different than any other Vette?
I'm thinking aftermarket will have a ball with a new bolt pattern for all new sizes, then there is the fact that these cars are engineered to the specific tire and wheel sizes with more computer controls to every aspect of the car.
Bolt circle is the same, but the lugs are 14mm, not 12mm as on the C7. Rear offset is dramatically different, but off the top of my head I don't remember the numbers.
Bolt pattern is 5x120 vs 5x120.65. Don’t know if we can mix. Offsets are 52 and 64. I’m guessing the 64 is the rear. Didn’t know about the larger lugs, where did you hear/read that?
