			Yay!  It's all about the contact patch and for track days and AX the Star Spec, RS-3, RE-11, and AD08 are all a good choice. They have excellent grip and hold up well to the heat of continuous lapping.  Far better than Michelin SS, or Bridgestone S-03/S-04 IMO.   
 
The latter tires are great all around street tires with good grip and manners but suffer under track day continuous lapping or AX events.
