SP Drilled and Slotted Rotors are a unique design offering the best combination of cooling and out-gassing. In fact, our design is so unique we would like to go over some of the details. The first thing we will point out on the drilled rotor is the chamfer. Unlike our competition there is no edge on our chamfer. This is accomplished by the use of an outer radius curve rather than a countersink. With the radius curve, or "Sinusoid Curve", it virtually eliminates an edge on the surface of the hole. With no edge, there is less stress build up, thus reducing the chance of surface checking. This smooth surface also makes the rotor more pad friendly by reducing the wear of the pad caused by the friction scraping against a sharp edge.

• All SP Performance® Rotors are 'direct-fit' bolt-on units. No modification to the OEM braking system is required.
• All base rotors are high-carbon, long-grain cast-iron units produced in either North America or Italy. They are the highest quality components available.
• Application specific CAD/CAM programming ensures proper machining for best looks, fit, and rotor integrity.
• Every rotor double-checked for runout at the factory to guarantee first-time, no-hassle installation.
• Widest variety of Applications, Designs and Styles of any major Performance Rotor Manufacturer.
• Rotors are available as Standard or Nickel-plated saving you money or enhancing the looks - Your Choice!
• Our SP Performance® Rotors now include an anti-corrosive coating on Standard Rotors for FREE!

Straight Drilled Hole A high stress and heat build up area forms at the intersection of the rotor and drilled edge.
Countersunk Hole Countersinking increases the external surface area of the hole, thus reducing heat, but still contains edges prone to stress and heat build up.
Radius Hole The Radius Chamfer increases the hole cooling area thus reducing heat, but still contains sharp edges.
SP *Sinusoidal Curved and Chamfered Hole Absolutely no sharp edges. The smooth design promotes cooling and minimizes stress, reducing the possibility of heat checking while increasing both rotor and pad life.

• Maximum air circulation for increased cooling
• Increased brake pad bite
• Faster release of brake pad gases
• Improved wet weather braking
• Reduced fade
• Increased Safety and Reliability
• Runs Cool.... Looks Cool!

Slotted

The nature of the slotted only rotor gives the greatest amount of braking surface, helps keep the pads clean, and increases initial brake 'bite'.

Note: Due to the nature of slotted rotors- a slight hum or whirring sound may be evident under heavy braking.
