Default clutch judder

I had recently the overhauled as the clutch felt sharp, i.e. operating
over a small range. The garage fitted a new 'clutch kit' to my car. However,
the clutch now judder, it feels like it will shake the drive train apart if
i am not very careful on the pedal. What is the problem?

The car soon needs MOT and I worry that the tester could damage the car.

Could be. The car has also developed a rough noise at 60mph but improves at 70mph.

What is the cure/risk if it's the engine mountings?

Have they skimmed the flywheel? they get hot spots (blue marks) these
should be removed.

If thats been done then there might be dirt under the flywheel/crank
when its been reassembled. All surfaces should be cleaned prior to re
assembly F/W, crank, engine block, gearbox.

You most likely won't know, but when tightening down the pressure plate,
was the diaphragm spring flat (no fingers out of alignment) where the
thrust bearing engages. This is a good indication of quality control of
the pressure plate and assembly. The clutch does not work evenly.

Could be the clutch is not correctly lined up , flywheel needs
skimming .

It has a rubber damper on top of the engine block if that is what you mean.
The problem is worst when starting in the morning. It is fairly ok as long
as I drive it myself, as I'm careful when releasing the foot from the clutch.
