I've just done a bit of work on my cossie over the last few months.

Anyway I've replaced the clutch with a standard one cause the car was still on its original clutch and that coped with the 300 and odd bhp.

Now I've fitted a standard clutch from Burton power

I've roadtested the car and when gets to 4k revs the clutch is slipping. I take it the clutch I've fitted is no good.
