After looking at all the options I decided on the Xtreme heavy duty cushioned ceramic clutch and a Xtreme 5.56kg chromoly flywheel (OEM flywheel is 7.35 kg). I looked at all the heavy-duty organic options and they didn’t have sufficient torque capacity.
The new clutch has much more bite and it is more difficult to launch in first gear without spinning the tyres. Initially there was some shudder and chatter on engagement but this has reduced as the clutch has bed in.
The increased bite of the ceramic friction material and the much stiffer sprung clutch disk has also caused axle tramp during launch and hard acceleration. The factory diff bushes are very soft rubber so have been replaced with SuperPro polyurethane bushes.
