: It seems that for many 540 owners it may be time for a new clutch. I had a very enlightening talk with Dave @ Sachs today about replacements for our cars. The standard kit is part # K70123 and lists for $731.61 this is pretty much OEM replacement. He can also get a Motorsports version that uses an 850il p plate part # 3482 924 001 to go along with disk # 881864 953.

: The 850 p plate lists for $301.44 and he had little idea on the disk price (they are not in the US YET). He did some math and estimated 23% greater clamping with the Motorsports unit. This is NOT a light weight unit, it is standard weight.

: We discussed the issues of blued fly wheels and he felt it is more probably driver error than design error. Missed matched shifts both up and down. You know like that time you down shifted from 5th to second while going 125 mph. You get the idea.

: The one problem with the Motorsports unit is that it requires some fly wheel modification. We dont know what (the mods are) yet but probably re drill and tap for the disk or lower the rivets for clearance issues. I will probably be doing this upgrade this winter. Need to find a shop to handle the fly wheel issues first. Any one want to join in the fun?

: I will also probably be doing cams at the same time. Any BTDT on the M60. Who are the best sources foe Sachs and also cams??

Just got my clutch replaced at 49K miles. Went back to the independent selling shop and they cut me a break on the parts. Still pretty pricy job at $1750 including a new flywheel and a new guibo just cause it was there. I've only had the car for 5K miles, so I'm feeling like I didn't destroy the thing. My flywheel and plate were blued, but not scored, though the disk was really thin, no rivets were showing.

I just feel like the clutch life is way too short for this vehicle.
