E39 M & Non-M Brake Rotor Offsets

[Meeners]

I'm playing around with some experimentation and I'm interested in finding some e39 rotor information. I know that they are 5x120 (check), centerbore is 74.1mm (check). I know that the front offsets in relation to the E36/E46 is different but without having it in front of me, I don't know what the numbers are without measuring myself. Does anyone have E39 brake rotor offsets are and how they relate to the E36/E46? Does anyone have a source for the information I'm looking for?

I was going to call RacingBrake, or Dave Zeckhausen, and some other Motorsport companies but wanted to check with the Bimmer Peeps first.

Thanks,
Meeners
