I've searched this topic, but have not come up with a definitive answer.

Does anyone know if M3 brakes (calipers, rotors, pads, the whole assembly) would fit an e90 328i? I know for sure it wouldn't fit with the stock 16", but I have 19" wheels (19x9 et36 +5mm spacer fronts and 19x10 et38 +12mm spacer rears) which should clear a BBK.

Thanks for you help!

Not sure but I think aftermarket rotors are what your looking for. Our OEM calipers are fine and with fluid, lines, pads upgrade along with rotors you can improve their performance by a lot.

Also, there may be an issue with the hub and the M3 rotor. Just think I remember hearing that but can't be sure.

Why not consider the yellow BMW Performance brakes?? Which I could get them for my 335 :-(

They do not fit. 335 conversion is the only direct OEM swap.

I think more R&D time needs to go into this idea (the yellow brakes are for the 135i and smaller than ours correct? )

So Fluid MotorUnion did it : http://www.modifiedcartrader.com/for...9-BMW-335-335i


But how?

By "335 Conversion" do you mean that 328i brakes can only be swapped with 335i brakes?

-or-

only 335i brakes can be swapped with m3 brakes?

If you have a 328 you can use 335i brakes

Jason: We fabricated a bracket for the front, and did a whole slew of welding/machining for the rears. We have a bracket ready to sell for the front, but brake bias will be affected without doing something in the rear. Most garages probably won't do the mods required for the rear.

I can sell you a 335 set up... then I can buy my BBK.

Thanks for messaging, at least now we have an answer.

Too bad it's not a simple bracket adapter for the rear; I'm sure we'd have them on the market by now if it was that simple.

OP, If you decide to go 335 (which I recommend, they're more powerful than 135 or performance), you'll need the 335 e-brake assembly for the rear as your current one won't work with the larger rear rotors.

Yeah I saw them on FB (they said they were going to re-dyno the car) I asked for pics of the bracket.

So in converting to the 335 e-brake assembly, does also require 335 hub carriers, bushings and bearings? That's some expensive cheddar just for an e-brake.

Or you can do what this guy did:

We are talking about a parking brake after all, so this should be plenty unless you plan on some serious rally type driving or parking lot hooliganism.
