And I must say so far I'd give my new centerforce clutch a good review, along with my general exclaim uhp tires. Together (so far) there a great combo. The clutch grabs great and dosent miss a beat and the tires have amazing dry grip. Im still in the break in period on the clutch so i havent cranked up the boost yet but im working on an exhaust right now so its just an open exhaust right before the cat. so it does boost creep to about 10lbs. I must say with a TON of weight striped, no a/c-powerstearing, decently free flowing exhaust, cone filter, great clutch and tires, and boost at roughly 10lbs this car cooks!! Cant wate for the fuel system, 16g, stainless exhaust, and front mount!!! Will soon easily be a 12 sec. car!!
