This guy purchased a replacement OEM Sachs clutch kit off of Amazon-

Original clutch-





What showed up-

looks like the ZF Formula 1 Carbon clutch

Just amazing.... retails around $6K

If it was F1 it would be $60,000..... lol

I though it'd be more but these guys talked to the manufacturer -

https://www.motorauthority.com/news/...mw-m3-customer

"These racing clutches are not sold to the public, which means one F1 team may be missing a very important component for its race car. Motor Authority reached out to ZF for comment on the value of the clutch and the company reiterated the part is not meant for the public and they would check on the clutch's value. We'll update the story should we hear back, but we estimate $5,000-$7,000.

The clutch features four discs and is much smaller than a street car's clutch. It can handle up to 664 pound-feet of torque, and it has a special diaphragm spring that lets it perform for short periods when temperatures reach 400 degrees Celsius, or 752 degrees Fahrenheit."

So, did it fit ???

Some craftsmanship right there. You had to take it apart now didn't you?

So how much did the BMW guy end up paying for this high dollar item?

F1 teams get their clutch packs from AMAZON?

Hi R,
So!!!
It appears that it's true.... GOOD things DO come in small packages!

Pretty special paper weight.

What was wrong with the old clutch?
Looks hardly worn. :-)

I call horse manure.

It looks like a motorcycle clutch.

(If it does prove to be a 60K race car clutch, I will deny I ever doubted the OP...

It looks to be a F1 clutch-

Specs say 97mm or a little more than 3 3/4"

Oh- the housing is titanium!!!

Sounds like somebody at UPS or DHL is going to have their nuts in the wringer!! Wonder what the F1 team thought, when they opened up the box they received, and saw an OE replacement, BMW clutch.....

Kind of reminds me of the clutch we used to run on the race kart. It worked great on the lower HP engines when we ran with the kids.

Interesting, my neighbor just recently ordered some very inexpensive items from Amazon and received a pair of very nice hard drive in the tera bytes each in size! I tried to swap him my brand new Z06 clutch for the drives but he declined! ( clutch is now sold )

Doh!
