I have a mk4 1.8 x18xe1 Astra which I am getting a new clutch put in from my local mechanics tomorrow. I picked up a 3 piece LUK clutch kit from eurocarparts today but on the invoice they have written that the CSC is now a modified version which is part plastic model and the old one being taken out may be metal. The guy at the shop told me they have only written this so that mechanics are aware that this is still the right part number but is modified to make it better. Has anyone else noticed the CSC on the current kits being different to the originals?
