Must admit. Lees looks like it must be a 4 ish kg flywheel and with that smaller diameter ap clutch the moment of inertia will be greatly reduced. Probably be alright in a kit car but a road car weighing 1 ton + might make life hard.

I was thinking more along the lines of a 6 ish kg fly wheel with a standard diameter clutch unit.

I reckon the stock flywheel is about 9 ish kg???
