Correct rotor hold-down bolt part number(s) for M Roadster?
For anyone that has replaced the rotors on a Z4 M Roadster, what is/are the correct part number(s) for the rotor hold-down bolts?
On realoem.com, they are called "inner hex bolts" and they show p/n 34111123072 for the front rotors and p/n 34211161806 for the rear rotors. However, when I tried ordering the -072 bolt I got a warning that "this part does not fit your Z4 M Roadster".
realoem.com also shows a total of four bolts for the front and four for the rear, which I assume is two for each rotor. Is this correct? Seems like other BMWs have only one hold-down bolt, but I've never replaced rotors on a BMW before.
