major bummer ! after recieving my new flywheel and clutch all was going well till the clutch cylinder burst !! doh ! then the problem became clear !! the uprated flywheel was not deep enough ! it was shy by about 15 mm hence no pressure to the pedal ! after a chat with courtenay they also realised that the vectra c cluth has a dual action , and there is'nt one available for the 'c' !! so beware if you own a 'c' 2.2 because no one makes a lightened flywheel for it !!
