    Sounds like a stock 540 front but I'm not sure.

    I have my 540 fronts sitting in my garage w/ new zimmerman x-drilleds.

    edit: calipers have about 90k miles on them. Zimmerman x-drilleds have about 3k miles on them. SS Brake Lines included. Only reason they were taken off was for the new Brembos.... if anyone is interested let me know.

    These all use the same brake rotor.

    Stock E34 540i rotors are 302x28mm, 540i M-Sport being 325x28mm.

    I just went downstairs and the e34 540 rotors are just a hair over 12 inches so 302mm is correct... for some reason I thought I read that the stock rotors were 12.7 inches... my bad.
