2011 GT500 STOCK with wheels/slicks 11.16@124

No, I was saying most guys go to a 4.10 and run 28" tires. This car has stock gears and is running 26"x10" Hoosier slicks. So .854" difference between the stock tires and the slicks, I’m not sure how much the Hoosiers grow it may be less as most bias ply slicks will grow and enlarge diameter wise towards the top end of the track.

This is the car
