I have used both of these tires on the same car 08 SRT10, and the same track. Watkins Glenn NY (High speed track) and Toronto Motor Sport Park ONT.(technical track)cups are ok. I thought I liked them (over ps2)until I tried the Hoosier R6. I never did wearout the Sport cups, (by tread depth) used them about 8 track days (110-135 Miles a day)and about 700 road miles. I think they were used up for the track though, as the color changed a Purpleish color on the sholders, from repeated heat cycles) The feed back was minimal to ok and stuck better than ps2. Now the Hoosier R6 stick much better, give better feed back and did not wearout from heat or wear, so far, but I only have 5 track days on this set. and 20 street miles. (should not drive the Hoosiers on the street).
I will say I bought both sets from PartsRack and Tire Rack heat cycled them before shipping. Heat cycling is the only way to go IMO.
By feed back I meen you can feel the tire slipping in the turns before it breaks free and you go spinning out of control. The Sport cups break away a little faster with less warning, and the Hoosiers have a nicer slide or slippage to them and you are still under control through the turn, as long as you stay "smooth" you should not go spinning out of control. You can push any tire beyond their limits but I feel the Hoosier R6 tire will be a better value for the dollar as long as you have two sets of tires and wheels, one for the street and one for the track. If you just want one tire to drive to the track and back the Sport Cup is the way to go. I hope this helps.
Good luck Have fun, BE SAFE!!
