CB99 also had drag radials. If you compare their 60' times, CB had like a 2.0 or 2.1. Phat SVT on street tires and no traction pulled like a 2.6. Huge difference. You can probably see what would happen if the s/c'd SVT could pull the same 60'. Alas, Phat tried the drag radial thing and the results weren't good.
