Yeah it's often a bit too easy to kill a button clutch
If i were you Dish i'd go for:
Exedy "Sports Tuff" Heavy Duty - TYK-6319HD: $205.70
Exedy "Sports Single" Sports Organic - TYK-6319SO: $364.10
Both will have a good amount of bite, be able to take daily "abuse" (riding etc), and still be sick on track without blowing T-fittys
