question, i've just noticed the bigger rotors and calipers on the 335s and was wondering if these rotors and calipers would work without fitment issues on 328i? this can be an inexpensive upgrade.

thanks

The 335 rotors would not be a straight upgrade since your calipers will have to be moved further out (caliper bracket needed).

can i use their calipers, meaning compatible?

you would need the 335i carrier brackets, calipers, pads, and rotors to complete the swap. Maybe the brake line too, but idk. but it's all bolt-on.

The rear disc will not fit.

Im thinking of changing the fronts.

You'll need to swap over the 335's caliper brackets, calipers, pads, and rotors. It's a common upgrade, but you can also consider other upgrades before and still have GREAT working brakes on the 328s.

I recommend checking out high-performance pads and upgrading the brakes lines first. PM me for our suggestions that work for our customers!

if you are mainly going for looks, get some rotora rotors. they come slotted and drilled for like $300 for all 4. jlevi's got them check them out

I noticed something interesting yesterday. I was at a dealership looking at a new 335i x-drive and it had the same type 161 wheels I had and the front rotor fit... BEARLY. The 161s are 17". I'm thinking the brakes will fit a 325/28 just fine if you have 17s and the proper brackets. I'm not sure though.
