Can I directly swap out my 550 rear bumper with an M5 without any modifications? If not, what else is needed to do so?

Thanks in advance!

 

I put the m5 rear from umnitza on mine.. It was pretty simple. .Im not sure why some people say you need zip ties for a certain part of it...Mine came out fine. .Was pretty easy too.. Perfect fitment.

 

What about an OEM M5 bumper?

 

This is jus tan educated guess, but to my knowledge the fenders are no different on the rear then the regular E60. So width and fitment should be the same.

Front bumper oem vs after market it's like an inch difference or something like that.. Pretty sure rear is the same.
