Hello everybody, I have the stock 914 clutch on a 2.5lt type 4 and everything is perfect, smooth engagement no slipping , BUT the springs on the disc have gone weak and I am thinking of perhaps a solid disc as its common on type 1 engines , but I can't find a solid 215mm disc, so what are the options here?
Thanks
Full Version: solid 215mm clutch disc?

I think you can get a four or a six spring clutch disk. Original was rubber and no springs, the 914-6 had a six spring disk. Try that one.

Maybe weak fingers on pressure plate
I don’t remember any rubber on the clutch of a 914
That was mid 80’s 911s/944s
Not on the 914

What symptoms suggest that the springs on the disk are weak?
For anything other than racing use, I'd recommend against a solid/unsprung disk. Clutch engagement with a solid disk is very harsh. The shaking and shuddering will drive you crazy on a street driven vehicle. Hard on the driveline too.

Maybe I was thinking of my 924...
