I have heard that the factory ///M540i is a conglomeration of the E34 sedan chassis and various left-over ///M5 bits, with the US 540i engine and six-speed manual transmission. Are the ///M540i's brakes:

Like the US 540i (302x28f/300x20r vented)?
Like the Euro 3.6 ///M5 up to 10/89 (315x28f/300x10r solid)?
Like the US 540i Sport, US 3.6 ///M5, Euro 3.6 ///M5 after 10/89, and Euro 3.8 ///M5 up to 6/94 (315x28f/300x20r vented)?
Like the Euro 3.8 ///M5 from 6/94 on (345x32f four-pot/328x20r vented)?

Just curious about that Frankenstein beast...

The Canada-only ///M540i has the monstrous 345x32f four-pot/328x20r vented brakes from the late euro M5s. That's one of the differences between the M540i and the US market 540i Sport.

Check for more info on the M540i and 540i Sport.
