Hi all,

This is my first post and i am currently upgrading my brakes of my 540iX mid 2019.
I already purchased the front brakes and discs of an F97 X3M and will install them together with new steel brake lines.

As i have the 370 mm discs in the back I was wondering if the rears of an X3M would fit on a G30 or do i maybe need the discs of an M2 as I cannot find the offset measurements anywhere.

Thank you so much for your replies…

I was looking to do similar on the back of mine, since i recently fitted F90 M5 setup to the front, but mine is early 2017. So are you saying the rear disc on yours is already 370mm? I thought the 540i's only came with 345mm rear, unless you have the Mperformance caliper upgrade which is 395mm front and 370mm rear

Hi, yes my car is from 09/2019 just before the facelift but with ID7 light. The rears for a 540iX are standard 370mm… i just bitten the bullet and ordered the rear discs of an x3m so i will keep u posted.
In the meantime here a picture of the front discs fitted…
