Questions for those of you that have done the Front M5 and rear M5 calipers and rotors. Did it change the offsets on the fronts and/or back? If so, by how much? Tried searching, but nothing came up with hard numbers of some sort. Thanks

 

I can only speak for the LCI E61. The front calipers are direct swaps, exactly the same offsets. The rears require the M5 hubs to be installed in order to get all the M5 hardware to fit. This will change the offsets by 20 mm which can be corrected with spacers.

This thread is a good resource.

Thank you. That's what I was looking for on the offsets.

 

I was thinking about getting the M5 front Calipers, SS lines, and buying these https://www.racingbrake.com/ProductD...oductCode=2327

Probably over kill on the rotors but what you guys think??

 

Wow 1350 for a pair of those! If you have the means, why not?
