When my coupe was in the shop in 2019/2020, the engine and accessories were removed to change the paint color. They gave me the guibo in 3 pieces. The previous owner probably installed a guibo when the 5 speed was installed and drove the car 3700 miles in 13 years. I bought the replacement Meyle flex disc from FCP Euro in April 2020.. Today , I found a big crack in it after just 5 years and 20K miles. The FCP price now is $50. The BMW OEM price is about $200.
Meyle markets many rubber products for BMW cars. Does anyone know who makes the OEM Guibo? I don't want a new guibo to fail after another 5 years.
 
This is one of those parts that given the price should only be trusted from the dealer. Supply and fit once the right way and forget about it. I believe Jurid makes them for BMW, our 80s dated coded original BMW part looked absolutely fine but replaced because of age regardless. MeyleHD parts are considered cheap chinese junk atleast here in the UK. We certainly wouldn't fit them to our customers cars.

the m5 guibo is the way to go. Confirm country of origin as DE.
I found 2 SGF/Febi on EBay. Is this first one the M5 part? If it is 35 mm thick and the Meyle now installed is 45mm thick, how is the 10 mm taken up?


Here is another guibo for 3 series BMW made by the same mfg'r.

Some interesting information regarding evaluating coupling condition:
Drew- Believe FCP offers a lifetime warranty if your crack warrants replacement (get a credit or keep it for a spare and go M5)

I'd seen an ad for a "race only" solid aluminum disc with PU inserts around bolt holes. Seems BMW has experimented with (and apparently decided against) an aluminum cage with coupling inserts

Attention!
An aluminium flexible disc (EGG flexible constant velocity joint) (1) can also be installed instead of the conventional rubber part flexible disc (2).
The aluminium flexible disc (1) must be replaced with a rubber part flexible disc (2)!


In-laws had one put in as part of a recall, then removed and replaced with rubber after the cage fell apart.
Have also seen uniform thickness ones with oval bolt hole surrounds allowing softer motion in one direction - equivalent to thick/thin sections?
Maybe they don't unravel - has anyone experimented?
