When my 350 was at 650whp i could hook second on concrete and thats about it. I like the Nitto NT05R's, and the ET street 2's. They only last about 3k miles but they will hook in second almost every time. I have the Toyo Tq's on my car now. They were ok in the beginning but fade off towards the end. I did manage to get 10K miles out of them. There slightly better then the R888 but not as good as the Nt05 or ETs2.

Good luck on the tuning!
