Make sure you change to the 325 slave. The clutch feel is horrendously pathetic (light) and vague with the M3 slave.
Yeah I have the 325 slave ready to pop in. I'm not looking fwd to the chatter one bit, I kinda liked how quiet my car was. Just knocking the output shaft back and forth in neutral i'm kinda getting a sense that it will be pretty bad.

UNRELATED SIDENOTE
I also did all my detent pins while the tranny is on the bench.. I connected up the linkage to test and holy crap it feels like a new box again. Never would have thought these would have made THAT much difference. snick.. snick...snick now. 1-4 were a snap.
Reverse and 5th kinda sucked. Reverse detent slipped out on its own with no problem. 5th I had to jerk out of there, obviously seized.

Finally completed the clutch project this last weekend.

I was injured for a bit while everything was apart.. bench grinder got away from me and sucked my left arm in, removing much of the soft skin from my wrist, causing some tendon issues. Those of you who've been in that boat know just how depressing it is looking at the car all apart up on jackstands, parts all ready to go in but can't work on it. Not only that, but the wife's complaining that she can't park the X5 in the garage because of the mess.... but I digress.

Anyway, I didn't end up backing off the pressure plate bolts any, I figure they're probably around 30ft lbs and they were "just snug" on the longer 1/2" crapfsman torque-wrench. I beat myself up over it, but in the end I'm pretty sure I was probably just overthinking it.

I have zero gearbox chatter, at least.. on a cold-ish california winter day. May be a different story as things heat up I imagine. I did get a little chatter when turning on the A/C, which I expected, but it's not horrible.

It's amazing how much better the feel is with a SMF. When shutting down the motor, I used to get a distinct thudding judder as the motor came to a halt unless the clutch was depressed. That's gone, it's more instant off, and quiet.

Maiden trip around the block I noticed a ticking sound on partial engagement, and a nasty burning smell. Today I noticed the ticking was completely gone, I imagine the TOB was probably just settling itself in. Burning smell is still there, kinda like a plastic bag on the downpipe kinda smell.. sorta. From what I'm seeing on the web, it sounds normal for the Sachs organic clutches when new and being bedded in.

Overall, the clutch engagement is VERY smooth. Much lighter pedal feel, even with the 325i slave. It's as easy as stock to modulate. Granted, I only have about 7 miles on it so far, but I think a lot of what has been hyped in regard to LWFW's is pretty over-sensationalized. Just get the PP/FW balanced together before installing. It feels like a really nice clutch to me, and I'm a picky bastard.

I WOULD say that, after a couple blips to ~ redline in neutral, it's a tad quicker to rev and fall, but not as silky smooth as it was before on the way up. I'd say there is a tad bit more harshness to the affair - and though mildly noticeable, it's not concerning. Again, we're shedding close to 15lbs from the rotating mass.. this makes sense to me.

All new detent bushings made the shifting feel friggen amazing. I'll follow up if anything changes or explodes. :O)

Heated it up pretty good for its smog check (failed with high HC 59PPM), but I can confirm that I do get gearbox chatter now. Grr. Oh well. Price we pay for go fast parts.

Did the CVV (very gummed up and nasty), spark plugs (3 were loose as a goose and blowing oil), changed oil... we have a pass! Barely, by 2 points. Scored a 53, where 54 is the limit.

If california ever lowers that limit, i imagine there will be a ton of old european cars parked in garages.
