Getting ready to purchase a new set. I've heard nothing but good reviews about the Hoosiers other than a short life span. The New ET Pros seem to be a good choice as well. Looking for some opinions. Car is ~3700 w/ me, Cal Tracs, and split mono leafs with adjustable rears, auto, Whipple Blower, 3.70 gear 9", 610rwhp/670 rwtq. These tires will be strictly track use only. 275/60/15.
