just wondering what the average mileage you should get out off a clutch bought the car about 3 month ago with 37000 mls on it.i now have 42000 mls on it and sometimes i feel it slipping when changing into 5th also when coming home from work tonight i was sitting in 6th at a steady speed and noticed the rev counter jump about 500rpm then jumped down again.there is supposed to be a mugen clutch fitted to the car according to some of the paperwork.
