All,
for those who’ve gone for larger brakes in their E39 tourings, specifically people who’ve taken callipers off other car models that aren’t E39s, have you had to change the wheel bearing / hub to change the centre bore to allow for the change in disc dimensions?
I’m waiting for some new (to me) callipers to arrive and they’re off another bmw, and that car’s centre bore is 72.6mm as opposed to the E39s 74.1mm.
Can I just get E39 specific discs to match the necessary diameter of the new callipers or would I change the bearing to match the oem discs that are spec’d to the new callipers?
Does that make sense?
Cheers

Are you experiencing brake fade with the current setup? If not, there is not much point to a larger setup.
I see. Sounds like fun with an S62. I was just checking as a lot of times people think bigger brakes will make you stop faster assuming they are not at the limit of course. Good luck with the build. I will say all 3 e39's I have had the pedal always was a bit soft no matter what.
Oh yea, I replaced the pads first and they were ok, but planning ahead, as well as changing the brakes before a potential catastrophic failure.
I’m still in the very early stages of the swap, and the M5 is nearly fully stripped, thankfully I’m using my 540i touring as the recipient chassis.

You will get more visibility if you move this to the general e39 forum. Nothing you are asking is specific to tourings except possibly the total weight of the car to stop.
