If it's time to replace the rotors on your STM Front Drag Brake Kit, these Spec-37 rings are a heavy-duty option that are often used with the RS3. These weigh significantly more than the standard lightweight rotor, but can handle more abuse. These rotors have a curved vane design and are side-specific. Rotors are sold individually as needed. Price is for one rotor.

• STM Front Drag Brakes
• Replacement Spec-37 GT 36 Curved Vane

Mount Side: Part Number:
Left Hand (LH) 160-12286

More Info:
Wilwood Spec-37 GT 36 Curved Vane rotors are manufactured from a proprietary iron alloy developed to withstand extreme temperatures with the highest possible degree of resistance against distortion, warping, cracking, and wear. The formulation for this alloy is a derivative of technology and materials that were significant in the development of the extreme duty military spec rotors that are manufactured by Wilwood. Combined with proven GT Series asymmetrical face slot pattern and individual dynamic balancing, you are assured the smoothest braking available.
