for the first time about 15,000 miles and 1 year after my remap i had clutch slip in 5th and 6th gear although i did drive the car hard the day before so maybe thats finished the clutch off , can i get just an uprated clutch disc and use the oem cover and Dual mass fly wheel?. say a sachs one or similar thats rated to way past the 306lbs my car makes?
