You can buy dimpled/slot rotors from BMW with oem diameter and thicknesses front and rear.

You can get M Performance Brake Disc, its dimpled and slotted but its retail at $400 for front and $250 for rear. It can be used on both M Perf brake kit of 2NH M Sport Brakes.

They are slightly larger than OEM. When installed, the braking system must be recalibrated at a dealer to account for the new diameter.

Part numbers below for M135i [same setup as M235i] dimpled/slotted MP rotors with OEM blue calipers ie 340mm dia front and 345mm

Not sure if they give any advantages apart for perhaps aesthetics though?

Are they drilled all the way through or just dimpled???...its a bit hard to tell from the images provided on the website

In Australia the M235i comes with dimpled rotors but im looking for completely drilled through ones

They are drilled but not completely through . They specifically state cross drilled rotors in another section. Nothing for the M235i though

Stop tech will make you a set....I am currently thinking about it. High Carbon, black e-coated, drilled and slotted

I just emailed dba in regards to these

http://www.dbausa.com/products/street-heavey-duty/

Much prefer the look of these over stoptechs.

I would love a set for the 2

[Pahzel]

Has anybody here found any aftermarket "bolt on" rotors on the 2 (other than the dimpled and slotted m performance rotors)? Specifically drilled, cross drilled, or slotted...

Just heard back from DBA,

"Currently we dont offer rotors for that particular model.* We may in the future, but at this point in time we arent offering anything.
Sorry I dont have better news"

We don't get the dimpled rotors as standard in Australia. I don't have them and have never seen one with them either.

Hey dtcoff, Are you sure? I took this photo in St Ives a few weeks ago and these rotors look like they have dimples
I might be wrong though...might have to drive past my dealer asap :-)

Yep, absolutely sure. You better check with your dealer if you are expecting them on your car.

here is the same car but a close up of the brakes, maybe this guy upgraded his rotors from M Sport to the M Performance rotors. Not getting my hopes up that they will be on my new car, but it would be nice

Are your guys' not vented? Mine are, but the previous owner did a few things that the dealer seemed unaware of
