@ ryan510 , I havent had to swap my clutch on my wrx yet but i have had good experience with excedy cermic / metal clutch packages, I had one of their stage 2 clutch packages with the triangle friction arrangement and it definitly got the power to the pavement. The only gripe I had was that the excedy stage 2 was less forgiving, if anyone else drives your car its a bit of a steeper learning curve because it grabs just a bit harder.
/second hand/One of the guys I used to work out with was running a stage2+ with a 6 puck and aside from it being really stiff on his clutch foot he was happy with the feeling. It was extremely solid but by the time he got to the gym he didnt have to workout his left leg anymore.
my advice, talk to a tuner, decide how far you want to go with your mods and get a clutch that's capable of handling a bit more than you think youll need, that way when you decide to upgrade again your transmission isnt holding you back.
