False. The Wrinkle wall is the tire hooking, the radial being so stiff has a higher chance of spinning (less shock) I was pulling 1.6's in the 60 on a radial. plenty fast enough for a stock drive train. Here is a vid of the car on a 1.71 60 vs a ISF. I was on stock rear end gears and stock turbos at the time.
7.7@91mph in the 8th. good for a 11.9-12.0 qr around 115-116
