I'm making 440 rwp right now and will be going with a KB supercharger and expecting about 600 at the wheels. The car is not going to be daily driven. It will only come out on nice sunny days. I'll probabaly take it to the drag strip occasionaly but that's all the racing it will ever see. I'm looking for a tire that will hook up with that much power. Also, something that's good on the street. Not too concerned about cost or treadwear, just want the best I can get. So far I've been looking at some Toyo Proxes RA 1's R888's and Nitto NT 05's. Let me know what you think. Thanks.
