P80 SMF/DMF flywheel clutch pressure plate weight

Post by tryingbe »

Since I am doing a dual mass flywheel (DMF) to single mass flywheel (SMF) conversion, I thought I'd share what I found about the weights of the clutch parts. Weights are going to be a little off due to wear and machining.

98 DMF setup (well used, disc worn to the rivets)

95 SMF setup (used/machined flywheel, new clutch/plate)

Spec SMF clutch setup (lightly used)

R SMF clutch and DMF clutch disc have the same diameter, but the DMF have more friction material

Obviously I'm late to the party but would you happen to know the 850r clutch disc thickness. I have a used disc and I wanted to know if its still usable.

No, no thickness.

For the cost of the new R clutch, just buy a new one.
