Recommended clutch kits

[vintagemechanic]

Just done my second 5 speed conversion for a MKII, pretty straight forward with a little tunnel cutting and fettling. So far I have use the clutch kits that come with the 5 speed kits (Toyota Supra) and they set up has been excellent, along with the adapter plate etc.

But I am not too impressed with the clutch kit, in particular the thrust/release bearings and pressure plate. Within a month the first one has started whining and now the second job is having issues dropping into gear and on this one it looks like the bearing is pushing off center to the pressure plate when engaged. I've read up on various groups that these conversion kits are quite fussy about the thrust bearing and pressure plate that is used. Some guys have ditched the clutch kits and purchased these elsewhere.

Anyone gone down this route? Thanks

Isn't the Jag about 1000 lbs heavier than the Toyota and then rear gear higher too? Seems to be light duty for a heavier high torque car. Just figuring.

Well these modified Supra boxes are pretty well proven, they been put on e-types, mk2s etc for many years. The issue seems to be relating to clutch kits provided.

I got hold of a company in the UK who offer up custom kits, and went down the route of using of one his pressure plates and roller release bearings and thankfully seem to have hit the jackpot. I was almost close to giving up and going back to the old style plates with the carbon pad.

I have two rear diffs and axles for the MK2, a 4:28 and a 3:27 which switch from track days to touring days. My MK1 has the same but 4:28 for auto considered city use and a higher 3:27 for touring on the 4 sped. All have sycncro trans from MKIis, which perform very well. Not worried about fuel mileage as track days negates that, and highway is the same as slower cars make you gear down. My MINI S hates 55 as it seems 4th is best but 6th comes after 70.
