Go for a standard flywheel and get an Exedy clutch but make sure that it is a complete kit by exedy and not a mix and match job selling for £180 etc. on ebay as they tend to be hap hazard kits and that is why they are so cheap.
PM me your reg number and I will see what is available for you in the morning.
if its a slight judder and you have a relatively good clutch and know how to launch a car without burning the clutch out then try a few hard launches - has been known to sometimes cure it in the past.
the clutch and fly wheel came from Techni-clutch not sure of the spelling.
Get the car back tomorrow as had to weld a crack on the bell housing. They say never known a clutch to give way so quickly the Fly Wheel is badly warped and blued.
