REAR pair of OE-type SLOTTED & PLATED replacement brake rotors for E90

PRICE IS PER PAIR (TWO ROTORS)

UUC rotors meet or exceed OE quality and specifications.  Unswept areas of rotor plated black to avoid unsightly rust ring.

High carbon technology assures highest heat absorption capability for longest and smoothest operational life.

Manufacturing details:

• Meets SAE J431 standard for grade 3000 gray cast iron
• Alloying: Copper and Chromium added to achieve specific hardness and tensile strength.
• Precision-controlled cooling during the casting process creates a uniform distribution of graphite flakes, thus increasing wear resistance and the ability to dissipate heat. In contrast, premature cooling of cast iron can cause iron brittleness, thus making the brake rotor more likely to warp or crack, especially when overheated under hard braking conditions.
• Run-out less than .004".
• Parallelism of machined surfaces within .0005" tolerance.
