I think Cups are really good for track and highway,it is necessary to warm them a little bit only.Even with rain they handle pretty good.They are very light too.
Expensive yes very expensive I ordered mines in 20" and spend over 2K at TTR.
I use them for highway for track I use R6 Hoosiers,will be cool to test R888.

 

Cups and R compounds on 20" wheels, why?!?!?!

 

I have 20" wheels and I hate to loose perf with the 20" wheels,like I said I use cups for Highway not for track.I go to very twisty roads so the Cup treadwear of 80 works really cool and believe it or not this tires last enough for me since I don't use the car every day so I like to have a good grip when I use the car.

 

i wonder if anybody use Advan A048...
