Lurker turning to post - primarily due to personal ineptitude I fear. I fully accept that I may have simply looked over the current answer and if so I invite you to "flame away" as I take no offense. But please also point me at said answer if so.


I have a 2015 F33 (435i sport line) w grey brake calipers. Fronts look like the brembo, rears appear smaller (Pretty sure 340x30mm Front, 330x20mm Rear). I want to get drilled rotors - admittedly for the aesthetic - to see if I wanted to do a true M Brake system upgrade.

I have to change brakes anyway.

From research and reading the forums I found the Zimmerman rotors - drilled - for the grey standard caliper (well mine is sport line) brakes... but the part number is for the pair. I have only found this available online in a couple places, and they state they are single rotors. As these would be directional I am at a loss.

Thus, does anyone know of any currently available rotors - preference is cross drilled but at this point I would consider slotted / slotted and dimpled / slotted and drilled, etc.

This has become basically a back to the drawing board item but I am hoping someone here has current info they can offer.

RockAuto has a plethora of rotors available for your car, including Zimmerman. You can review their availability in drilled/dimpled/slotted as a start if you have not done so yet:
