After 2 and a half months of nursing my slipping clutch it was finally replaced yesterday in favour of a Helix item by the helpful chaps at Rtech power.
The DMF was in good working order so did not need replacing.
Whilst the clutch is slightly stiffer than standard, it is by no difficult to use, testament to this being the hour of clutch/de-clutching on the M42 thanks to the kind people slowing down to gawp at a car accident. If anything it appears to have softened in the 150 miles I’ve covered since.
There are no strange squeaks or rattles in operation, gear changes are now very precise with much quicker pick up than before.
