For your application... I just don't think you would be happy with anything other than a drag radial in the rear. My old cobra put down 466 rwhp and when my 555R's were brand new, they would stick and go. But at 615 rwhp, you may still spin them. Like someone else said, you may have to run some M/T ET street drag radials if you want no wheel spin from a dig. 315/35-17's are a good size for your rears.
Any of the NT05's, NT555R's or NT555RII will be fine up front and all about the same... just whichever tire you tend to favor on there really.

Yeh i knew a few people that autocrossed with that setup and did good.
Whats your thoughts on the NT555R and NT555RII in rear?
I can get the NT555R,NT555RII and NT05R in 315/35/17. Whats your thoughts on them if all are same size.
My front are 275/40/17. Should i keep my rears 35 or maybe go up to 40?
