I don't think my car is near as fast as yours but I don't run screws in my 30 x 9 radial Hoosier slicks and they work fine for me. Heck I have been driving them on the street for about 8 years (on two sets) also. And they hold air all winter in the garage sitting on the ground as I don't lift my car off the ground. I also love how they just handle better then the bias ties do. Ron
