Coming back to this..
I actually went for a Helix 4 paddle in the end.
However, nothing wrong with the performance of the clutch - although does shake the gearbox like hell if you don't give enough revs. The clutch cover is particularly heavy.
Anyway, I have strong reason to believe that the current Helix setup I have has caused excessive wear to the crankshaft and resulted in serious end float issues.
So, want to go back to a slightly softer clutch and from speaking to a couple of people, AP are much better.
Can anyone recommend a clutch that's good for 350-400lbs ft and isn't going to shake the car to bits? Didn't really want to have to get a paddle again. Is a 6 paddle much better than 4?
Must be lots of people with experience of clutches now with all the Zetec turbos floating around?
