SP Performance S55-147-R Cross Drilled and Slotted Rear Brake Rotor

The SP Performance S55-147-R is a cross drilled and slotted rear brake rotor engineered for drivers who demand superior stopping performance over stock. Manufactured in the USA, this rotor is machined and plated to order by SP Performance employees and built to meet or exceed OEM specifications.

Key Features:

• Sinusoid Curved Chamfer Drilling: Cross drilled holes are machined using SP Performance's exclusive sinusoid curved chamfer method, eliminating sharp edges to promote cooling, minimize stress, and reduce the risk of heat checking or cracking
• Directional Curved Slots: Slots increase brake pad bite, improve air circulation and cooling, vent gases, reduce brake fade, and help prevent brake hydroplaning in wet conditions
• Corrosion Resistant ZRC Finish: Available in Gray ZRC, Silver ZRC, or Black ZRC — SP Performance's ZRC coating provides galvanic protection against rust, corrosion, and oxidation, bonding permanently to the metal surface after heat cycling
• OEM-Quality Construction: Designed using CAD software and produced on CNC machines for consistent performance; machine balanced and disc ground to OEM specifications
• Direct Replacement Fitment: Drops into place without brake system modifications

SP Performance cross drilled and slotted rotors provide the combined benefits of optimized cooling through the drilled holes and continuous gas and brake dust evacuation through the slots, helping to eliminate brake fade and maintain consistent stopping power. The S55-147-R is backed by SP Performance's workmanship warranty guaranteeing the rotor against cracking for the life of the rotor (measured to minimum thickness).
