Looking to replace the inherently weak stock clutch as soon as possible. Has anyone had success with this improved Sachs clutch.

We were still waiting to hear from 540is and some other fellow whose name eludes me at the moment.

FamilyM5-

Here's the most detailed thread on the Sachs Performance Clutch:

Short version: my sources tell me it is not a direct bolt-on replacement, and that machining of the flywheel is required for a proper fit. I have yet to follow-up with the folks at Sachs near Cleveland, OH, but I will. I, too, am at the end of the road for my original clutch, and am exploring options.

540is was to have embarked on his install in Sweden about two weeks ago.... Any updates, 540is?

hmm... what kind of machining on the flywheel is required? I wonder if it would work with the stage 2 dinan flywheel....

Are you SURE you want to get the dinan stage 2 flywheel? I know you're waiting for someone else to try it out first before getting it yourself but I've said it before..you WILL end up with a M5 that sounds like it has a diesel engine. Go with the stage 1 flywheel instead.

I think, when the time comes, that I am going to get a stock clutch and send it to Centerforce.

They will upgrade the clutch substantially and send it back ready to go without any further mods.

Cost is 3 or 4 hundred bucks for the upgrade. I dont know how much a stock clutch costs.

This sounds like the best option I have heard so far.

well, in the long term, that's what I want in the car... Since I've more or less decided I will send the car back to Hong Kong in 1 or 2 year's time to be used as a track/illegal street car, it wouldn't really matter if it sounds like a diesel engine, since it would not be a daily driver anymore....

I would say the disk is as important as the clutch. The disk is what overheats and breaks down.

This is where you depend on American knowhow to provide what you need for high torque motors in a heavy car.

And remember, the more exotic you go with a disk, the more it leans toward race, not street, characteristics.
