Red SC Red if you are running 600HP it doesn't matter what tire is on the back. Even slicks will have to be screwed to the rims. You have a light car and BIG HP. Your rear suspension has alot to do with your traction issues. Not sure which car you have but to start with, a 4 link setup or watts is needed to control a rearend like a Jag or IRS. Solid rearend like 9" needs the same thing. Shocks and spring rate are very important for weight transfer and getting the tires to slick to the road. You need to video your car taking off. The car needs to be on a level ground. The correct air pressures are also key to this problem solving. The rearend should squat about 1- 1.5"'s and leave without and tire slipping. A couple of guys are very happy with the Avons. You may also want to look at 17" wheels and tires if you have the room. Any cobra with 500HP or better can blow the tires off the back of the car without to much problem, the trick is getting it to hook all the time.
