Interesting, although I didn't change my clutch (plenty of wear left) when I dropped the gearbox for overhaul I was under the impression that it was a standard Ford Clutch from Sierra or Granada 2.9 V6 (fitted with type 9 box not the MT75 as there are two types of clutch kit). Indeed IIRC my clutch compression plate was stamped with a Ford part number. Anyone else got any info on this as I would appreciate being corrected if my assumptions/memory are wrong.

Might help

RE flyhweel issue, Having had 8 or 9 of these cars all having the same issue to solve...this is where the generic Ford clutch plate when bedded in then begins to slip under load (3rd-4th gears). The rivets on the centre fingers of the plate clash with the I.D. of the flywheel face and you need to be check that the rivets have enough relief to allow the plate work correctly. IF needed machine 1.5mm deep by 2mm off the inner face of the flywheel.

Note that the generic 2.9 granada clutch kits that are in the market place have problems when fitted to the TVR flywheel and after a few thousand miles the centre rivets clash and the clutch again starts to slip at high load points (ensure that the people and or yourself check for this) as I have machined some 30 odd flywheels in the past to suit. Adrian@

After 8 Private mails, on why this is so...the OE plate on this car is an AP version and this is matched to a flywheel where the driven plate area (the face that the plate runs on) has an I.D. that where it drops down to the bolt facing area is 2MM TOO SMALL and requires a relief machining from the flywheel to allow the plate rivets to drop into as the friction material wears away....OR the engine side of the plate runs on the rivets and the clutch slips.

Thanks, Perhaps mine has been machined in the past? Although I can't make head nor tale of what Adrian is trying to say, other than the standard one doesn't fit without machining. Does anyone have a picture of the differences/required flywheel machining? Not an issue for me at present and hopefully not for a few years.

The flywheel on mine is a 2.8 one and not the lardy 2.9 flywheel. I've been advised that the 2.8 flywheel is the easiest way to connect the 2.9 engine to a type 9 gearbox - the 2.9 engine usually connects to a MT75 gearbox and the 2.9 flywheel is thicker and heavier.

So, maybe an uprated 2.8 friction plate would do the job - something that it sounds like TVR used from Adrian@'s post.
