Got someone selling some M235 m sport brakes with disc and want to know if they will for on my 2012 328i?

I have 18" rims already.

Are you referring to the blue M sport (S2NHA) brakes? They should fit except the rear rotors which you need to check the compatibility - (RealOEM shows that it is the same rotor).

Please note that this statement is valid for North America market.
I do not know how to check the codes for your particular market.

Rear rotors will not fit, as your 328i has 185mm handbrake diameter, while M235i has 160mm- same as 316i-320i RWD do.

The blue rear calipers are all the same for 316i-335i.

The blue front rotors & calipers fit any engine/transmission type.

Just remember there are two types of blue rotors+calipers- 340mm & 370mm. So if you occasionally get a 370mm ones which were installed on 335i, the minimal wheels diameter is 18" then.
With 340mm it is 17".

If your car us of US market then they fits ...
Only EU x28i n20 engined cars have big bore handbrake drum rears.

So answer is yes if we are speaking about a sale on US market/cars and not if this sale is going to be on EU market.

PS
Fronts are ok for both matkets ...

Really? So the US 328i have the same 160mm rear handbake as the 320i has? Never heard they did so for US.

328i & 428i of US market are of 160.8mm drum hole rear handbrake.
EU , not ...
Why ?
Nobody knows except Bavarians
