When people have been putting these clutches in do they buy them in a kit (CP2000-18) or do they get the pressure plate and clutch plate individually.
The reason i ask is because i purchased the kit but ended up being sent the two individual parts, pressure plate and clutch plate, and once fitted the car was suffering major juddering, the gearbox was removed (after about 20 miles!) and the clutch plate was goosed (burnt, loose fibres, deepish ruts) and there was burn marks on both the fly wheel and pressure plate.
The fly wheel was skimmed and checked prior to the clutch being fitted. A new release bearing was fitted.
Basically what im asking is does the clutch plate have to be matched to the pressure plate and hence put in a kit or is it ok to get the two parts individually as i did?
Has anyone else had a similar problem?

All input is greatfully received, xxx
