How to upgrade front and rear brakes on a 2.0i using factory parts?

Post by Pbondar » Mon Aug 07, 2017 7:46 pm

As the title suggests, how easy is to upgrade the brakes on a 2.0i using 2.8i or 3.0 or 3.5 factory parts?

And/or do any of those brakes cross relate to other BMWs...I'nm sure they must..

I don't feel that my 2.0i is underbraked but wanted to look at the options..

The brakes look puny when compared to a 3.5 or Z4M but feel strong..

Geeky questions are:

1) How does the load proportioning s/w cope with changes in brakes?

2) Any changes to servo's or anything else?

3) I assume the rear parking brake is a nighmare on Elm street in this context?

4) What happens if you just uprate the front?

1. It wont know you have changed discs and pads and will continue to operate in the same manner.
2. Not essential
3. Nope
4. Probably a bad idea, you would upset braking balance.

I understood it was the front brakes only that were larger on the 28i with the rears staying the same? :?
