By type of tire I mean street tire vs track tire. BTW, how would you get your track wheels to Texas anyway? In the backseat/trunk? Trust me, against ME in my street tires (all I have) you will not need any type of edge...heh. Either way should be a blast I can't wait to get back out on the track myself, and ride with you Sunday at Road Atlanta. I want to see your car FLY through those turns!
