The only way to improve the clutch is to use a smaller diameter multi-disc
type that reduces the diameter of the rotating mass.
Frankly, in a TR-4, it ain't worth bothering with. I mean it isn't as if you
were dealing with something that revs in a snappy sort of fashion, like an
MG, for instance ;-)
The lighter flywheel is worthwhile (I used one in a TR3 I had) but beyond
that it is a bit of a waste of time - spend the money on a custom forged
crankshaft to make that tractor engine (and I say that as one who is rather
fond of them) stay together longer at higher rpm.
I assume that you have already whacked off that great lump on the front of
the crank (aka the fan hub/starter dog, if it is an early car) and replaced
it with a regular extension and bolt? That reduces a minimal amount of
rotating mass, but also eliminates a source of potential vibration.
