Where are the performance upgrades??

[MADALPHA]

Hi guys, I'm currently giving the 120i (Auto) some maintenance and well I figured it was about time to add some stronger components to the car. First step was changing all filters plugs etc. and now the car is also on LM synthetic oil. I've set my eyes on the cooling aspect of the car (living in a tropical country HEAT is the #1 enemy) and have looked into an aluminum radiator. I have also decided to add some slotted & cross drilled rotors with some good pads and this is where my dilemma comes in. I cant seem to find any aftermarket rotors for the uf51 e87. Can anyone help.
P.S I also have access to an e90 M5 engine. I'm familiar with the M3 engine swaps but has anyone come across an M5 swap into an E87? Thanks in advance

Hi guys I've discovered that the E87 (120i) & some E90 models (320i, 323, etc) share the same brake systems. I'm trying to confirm whether the rear rotors are the same as well.

I'm trying to also understand the US & Euro # system. What counterpart does the Euro 120i have in the US?

Since I cant find any aftermarket performance brake kits for the E87 120i I figure I can use one for the corresponding E90 counterpart since the aftermarket scene is big on the 3 series. Any guidance would be great.

Thanks for the

For any 1er looking to add some umf into the hatch.

Hey guys I bit the bullet and got a 32 way adjustable coil over system for the 120i as well as a strut bar to stiffen the front end some more.
Attached are the images. In the future I'll look at adding stiffer bushings to the entire system instead of swapping out arms and such. Enjoy.
