Obviously the 370mm front rotors work on the 320/328/330s as well, but you do need to make sure you have the right caliper for whichever rotor size you're getting.




Used calipers are fine. I haven't heard of any with leaky piston seals unless somebody took them apart before (and you can order the piston parts).
Yeah I see both for sale online, just a bit hesitant about offset sizes with 18" rims I have and want to get. Think ET30 is too little for 370mm rotors and calipers?
