SP Performance Diamond Slot ZRC Front Rotors (Pair) Subaru WRX 2002-2008 SP Performance

Part #: D47-203

SP Performance Diamond Slotted Brake Rotors perform like the slotted rotors, with the added bonus of the dimples. The slots on the brake rotor surface are used to expel the brake dust away from your braking surface and wheels, keeping the braking surface cooler. The Dimples, or Diamonds, on the surface of the rotor keep the braking surface cool, without the risk of forming stress cracks like the cross drilled rotors. All SP Performance Brake rotors are machine balanced and disc ground and meet OEM specification. The Diamond Slotted Brake rotors are direct replacements to your existing brake rotors and require no brake system modifications. All Slotted brake rotors come with your choice of coating for rust prevention. They are available in Silver Zinc Plating, Black Zinc Plating and Gray Zinc Coating.All Rotors are machined and plated to order by SP Performance employees.

Product Highlights
Directional Curved Slots: Helps increase brake pad bite, improves air circulation and cooling. The slots also vent gasses, reduce brake fade and stop brake hydroplaning in wet weather, reducing stopping distances.

Diamond Slots: Creates a recess to dampen expanding gasses that push against the brake pads and gives the rotors a very unique look.

Corrosion Resistant Finish: Corrosion resistant finishes give a clean look behind your wheels while preventing rust, corrosion and oxidation. Available in a Bright Silver Zinc Plating, Black Zinc Plating or Gray ZRC Paint.

Quality: Our brake discs are made using the finest quality castings that exceed OEM specifications. Designed with the use of CAD software and produced on CNC machines insures the highest quality and consistent performance.

Diamond Slotted brake rotors are used to move unwanted material and gasses away from the brake rotor and brake pad surfaces while keeping them as cool as possible.

The gasses are created by the repeated use of heavy braking, which causes a layer of brake dust and gasses to build up between the brake pad surface and the brake rotor surface. What this does is actually push the the brake pad away from the rotor surface. By adding the slots onto the surfaces of the brake rotor, this allows those gasses to escape which in turn creates a solid bite between the brake pad to brake rotor. By allowing the gasses to escape, the brake rotor and pad surface stay cooler which will help eliminate brake fade.
