Just removed from my car because it couldnt handle 3rd gear clutch kicking but for normal road use has been absolutely fine.
It only slipped 4 times and after that I was careful to not fcuk it up and although it has a few heat marks I'm confident it will be fine on a 300ftlbs road car or sub 260ftlbs/300bhp if you do silly clutch kicking antics

.
Its done less than 2000 miles, mostly motorway or while running the engine in. The flywheel is a lightened standard one bought from APT which weights 9.6g (approx 4kg lighter than standard).
£180 plus delivery or I can bring it to JAE.
