I've had 2 of the Spec Stage 2 clutches and been very happy with them - the first one survived 45k+ miles with very aggressive driving and hundreds of high rpm launches. They are very streetable too. I will be getting a third when I need it.

BTW, sorry if I jack the thread, but how much life are people getting out of their clutches? - Ive averaged about 45-50K out of mine
