I wonder which slave is fitted because as far as I can work out in the erm... numerous.....
clutch threads it seems to be the slave that gives out (and sometimes the master!) rather than the clutch itself.
But at that price and with a 2 year warranty it's got to worth considering.
They're only about 25 miles from me so if I get a chance I might give them ring and pop over.
Andy.
