Concur e46 M3 Rears work. I dunno bout same part number, but rear brake rotors are same size on e46 m3 rears and e39 m5.

Slim pickins for drilled front.

Best bet- StopTech BBK front with drilled rotors, and e46 m3 rear rotors.

Turner Motorsports has the rears on sale here.

G/L and keep us posted on your decisions! I've been thinkin this route for awhile now. Just too many other mods currently in process.

This infromation is very intresting.
So basically the only set of rotors from the E46 M3 that fits on the E39M5 are the rears correct?
That is good news I have a brand new set of oem E46 rotors stored in my garage that I can use on the M5's next brake job.
