Default m5 clutch conversion ?'s

I can get the e34 m5 clutch kit from sachs for a decent deal through my dad. do you use the whole kit including pressure plate, disc, throwout bearing? do you have to do anything special like install the disc a certain way. I am going with a jb racing aluminum flywheel, as I heard they were made to be used with the m5 setup. thanks guys. tj.

The clutch has to be installed backwards with the JB racing flywheel. That's the exact setup I have. I like it. There's a small bit of chatter at idle and at low rpms when engaging. Very happy with it so far.

The only M5 bits that you use are the pressure plate and clutch. The throw out bearing needs to be E36 M3.

Weights, FYI...

OEM Setup:
Sachs M3 Clutch = 2 lbs
Sachs Pressure plate = 10 lbs
Luk Flywheel = 23 lbs
TOTAL OEM setup = 35 lbs


M5 + JB setup:
M5 clutch = 4.5 lbs
M5 pressure plate = 13.5 lbs
JB Racing Flywheel = 10 lbs
TOTAL M5 + JB SETUP = 28 lbs



Should be roughly a 7 lb drop in rotational mass.

so is this kit I am trying to create this exact kit from bimmerworld or not? this kit. http://store.bimmerworld.com/shared/...t=products.asp . or are they cheaping out and using a m3 pressure plate with a m5 clutch disc? besides weight what would be the main difference between the two pressure plates? what slave cylinder should be used when going with a lightweight flywheel? it is the one with the oem sachs clutch for 850 with the jb flywheel.
