I am after one for the Megane. Most seem to fit them with an unsprung clutch plate.

For the meg, ttv fly and standard clutch comes in at around £500. Ttv r26.r fly and clutch, just over 6 and ttv fly and helix clutch is over £1000 like my st setup.

So I figured for my st turbo engine that I am still building I would try the Blacktop flywheel with the late 170 clutchplate (240mm) And space the thrust bearing if needed to make up the differance in height.

I am sure it's already been done.
