Just to throw out another option, I put a Spec "stage 2" clutch in mine last year, and I've been very happy with it so far. It'll run you about $340-ish. The "stage 2" supposedly means it will still work well after some power gains, and it has a kevlar friction plate for "longer life."
LUK products are fine we use them often here in the shop. Stay away from aftermarket "performance" clutches. I would never use a SPEC product in anything too many issues all the times people brought them to me to install.
nothing wrong with LuK parts, part of Schaeffler Group of motorparts suppliers - Porsche wouldn't have given them a supplier award if they were substandard!......at least I would hope not, not at the speeds we can drive legally over here
