Which clutch slave?

[gobuffs]

I can't find it in my receipts. Which clutch slave do I need with a ZF? I lost one at the race school this past weekend and I need a new one ASAP. I am thinking one from an E36 325 is the one I need.

TIA.

I usually use the slave that comes with the tranny (e36 m3).

Ok. I have an 01 M coupe and a 328. I guess I should check realoem as they probably all use the same clutch slave.

[gobuffs]

The M3 one appears to be 22.2mm, the 328 one is 20.64. Doesn't really matter it appears. Whatever my parts guy can find in stock is what I will use.

I thought the 328 has the same tranny as the 5-speed M3 (and therefore use the same slave.)

if you use a ltw flywheel w/ the zf then use a 325 slave (better pedal feel)

That's what I was thinking. Thanks.

+1 on this, I'm using the UUC stage II clutch/flywheel (8.5#) in my car and was instructed by UUC to use a 325 slave (factory PN ends in 045) or else the clutch pedal will be really soft (they're words; you can basically breathe on it to operate it).

I'm currently trying to get the air out of the clutch master as I was an idiot and blew out the old slave while swapping booster and completely drained the clutch master so I can't give any good feedback to confirm but I will once its available

Took the tranny out just in case. Good thing I did. The slave failure was a symptom. The root cause was a throwout bearing explosion. Doh.

Fwiw I'm running the stock clutch and tranny setup from a 98 m3. I ran the corresponding slave as well. Worked fine but the clutch would engage with the pedal released right off the floor. I switched to the e36 325 slave and it now engages at a normal pedal height. And the pedal is also stiffer now.

I'm using the Getrag 250 tranny with dual mass flywheel on my M50 swap, should I use the stock M20 slave cylinder or the E36 one?
Thx.
