What I've discovered is that the design of the OEM rotors are BMW 2-piece brake rotors with iron friction ring with a lightweight aluminum rotor hat. This design , to me, has flaws and is prone to excessive heat and warps rather quickly. I've had the same problem repeatedly. I switched to Zimmerman one-piece cast iron rotors with OEM pads, and I've driven very hard, and it hasn't happened ever again.

Pros: drove very hard, hasn't happened

Cons: prone to excessive heat

Vehicle: BMW

Cons: other warped fast

Zimmerman rotors are pretty much the item of choice as far as I know, and I’ve always sworn by Hawk HPS pads if you’re street driving.

Pros: item of choice

I just bought zimmerman cross-drilled rotors for the fronts. Cross-drilled rotors are lighter but do not dissipate heat better (less material to soak up heat). Stock or slotted rotors are best for soaking up heat.

Pros: rotors are lighter

Cons: do not dissipate heat better
