F30 brembo's swap on E90??

Does anyone know if this would be a direct swap? And will I have any issues with braking performance??

yes they do, depends on the rotor size you use you may need to run 19's if you do full F30 perfromance pack

Also of note, some threads had people shave the bottom of the caliper for some reason

But it is only front brakes that is i direct swap right? The rears are a bit more complicated.
18" wheels should do it according to severel vendors

I know the the front caliper/rotor can be directly swapped. I couldn't find a clear answer about rear fitment. The rear rotors from F30 will not fit E90, but can we get the F30 rear brembo calipers to fit on the E90 rear rotors with out fitment or performance issues??

You can get a Brembo parts App for your phone and cross reference both models. I would suggest paying a little extra for the UV Brembo Rotors

This is a fact that they do direct swap ? The fronts that is ... What if you do non OEM rotors ?

Would someone be able to give me a complete parts list of what would be needed to do the swap ? Please :-)

Someone did it and said the brake pedal feel was really bad. something to do with mis-matched caliper piston volumes compared to the E90 iirc, so make sure you look into that.

When it come to swapping brake calipers, the reason the brake peddle feels soft is because the total area of the new calipers (inside the caliper where the fluid is) is larger than the previous caliper. Brake master cinders flow a set volume of fluid, which is matched to the caliper of the vehicle. In the case of upgrading within the same car family, often the larger piston volume can be compensated for by swapping in the brake master cylinder from the same model the calipers are coming from.

the brake master cylinder from the F30 is not an upgrade size over E90, so I'm curious why braking would feel soft

These guys ?

I been told the rear will need some machine work, I am not totally sure what needs to be done, but as far as I know, all parts from the F30 Brembo kit can be bolted onto the E9x once the machine work is done.....

I've fitted front and rear F30 performance rotors to a E90 335xi. We used the 6-piston fronts and 4-piston rear calipers from the CTS-V/Camaro ZL-1 (custom machining and custom brackets of course).

Similarly, rallyroad has a front and rear 4-piston Brembo caliper kit for the E90/E92 (xi's included) that uses the stock E90 335i rotors. Brake pads cover the friction surface of the rotors perfectly just like an OEM brake kit.

The F30 front and rear performance rotors on an E90 335xi. We had to modify a set of Toyota Supra rear pads to sweep the rear rotor surface. It definitely wouldn't be ideal for a production kit, but we made it work. The front CTS-V custom machined calipers and brackets do a pretty good job on the front rotors. It's been a year and no rust ring has formed on the inside of the rotor. The brakes still look and work great.

So the F30 rotor front & back fit with no problems? No modifications?

No modifications. My dealer pulled some strings well over a year ago to get me the factory F30 performance rotors. They bolted right up.

Machining the calipers into radial mount versions and creating brackets took a little longer, but was well worth it.
