what type of clutch do u guys have?

[papajetta]

i have a 89 535 ( e34 ). turbo
i used a e34 m5 clutch set up, with a e28 solid flywheel.
i,ve had it for about a year already, but it has never felt like it should.
i could barely break tires loose in second. plus when power shifting hard from 1st to 2nd, and 2nd to 3rd, you can feel the slipage a lot.
plus the clutch pedal felt much weaker than before, like if it needed to bled.

any ideas? or similar problems?or alternatives?

what i changed new:
e34 m5 disc, cover bearing

what i changed used:
e28 535 flywheel ( it was cut before instalation )

what i did not change:
clutch fork, fork pivot, slave cylinder, and stud for the slave cylinder.

any help would be greatly appreciated.

so you only used the clutch disc? That could be your issue, lack of clamping force. The two are made to be used as a set.

I am using the e34 M5 disc and pressure plate and my clutch has worked fine at 10psi. After driving around with the M5 clutch in the e28 the first time I drove my 323i I thought the clutch had gone.

i did change both as a set, disc and cover.
( i dont think u can get them seperate )

however a fact i forgot to mention, when i measured both complete flywheel w/clutch set ups, to see how deep each was, the m5 was not as deep as the 535 set up.
So bmw told me that should be the reason why my pedal feels soft: because it was reaching the fork later than the original one.
but i still cant add up why that would have anything to do with slipage

strange.

I used the same shifter fork on mine with the 260/6 transmission. Plus I replaced all of the clutch components at the same time. Master slave cylinders, connecting hose, hard line, blue hose , T/O bearing, My clutch is definately stiffer than it was with the original 535i clutch.

IMHO either ///M5 clutch is better than the stock, but will not hold great at the higher torque levels of 400lb-ft. It will start feeling like it slips as you say on hard shifts quicky, like middle 4 digit milage.

There are upgrades from TCD(for sure) and Sachs I believe.

I got a Spec stage 2 from TCD for my 86 535i engine. Havent installed it yet but ill be sure to post its performance.

Spec Stage 3 clutch, M5 pressure plate - TCD's old setup. Still grabs like a champ - still acts like the first day I installed it.

But yes, it does have the notorious "Chatter" unless you work it just right...... it doesn't bother me though.
