I am looking for a new clutch for my 7M, I took my car to get tuned last May and my current clutch a clucth master stage 2 gave out at 14 psi at 450WHP. Jeff Evans form Evans tuning who tuned my car said if i turn the boost up to 25-30 psi I should be able to break 600WHP no problem. I am now looking for a new clutch that can handle the power. this car is going to be driven mostly on the street so I am thinking of using a SPEC twin disc kit ss trim. I was wondering if anyone else is using this clutch or knew anyone who is or if their is another clutch that would be street-able in the same price range about $1600-$1800?
