I am one now, and can't decide if I'm gonna make it better or worse. -stay with the sport cups, step up to the Hoosier R6, try the super sports and be happy with those cuz they last longer and are almost as good as the cups.
If you run the Cups on multiple track days, you then have to deal with them being well worn when commuting to the grocery store afterwards and such.... and in the rain they ****.....
You will scratch your head when you reach for your wallet to buy another set only to realize that you have not racked up a lot of miles...... you had a lot of fun... but not a lot of miles...
With Super Sports you can run them at the track starting out 22 psi cold and run them all day like a sport cup and with surprisingly confident grip but less visable wear when comapred to sport cups....
Once you get to the mileage where you typically would have to replace sport cups you will be pleasantly surprised that the super sports still have lots of tread left and can still run in the rain better than the sport cup..... very nice feeling when you are using the car for commuting during the season knowing you have lots of tread left....
