Product Details

Mercury Cougar 1986, Diamond Slot™ Dimpled and Slotted Vented 1-Piece Front Brake Rotors by SP Performance®. You want your brakes to look like a million, but need them to stop on a dime. SP Performance Diamond slot rotors deliver. They stop on a dime and add a little bling-bling to your ride. Designed for strength and better stopping power with an exclusive new look, Diamond Slot Rotors not only look cool, they also stop as good as they look. SP Performance Diamond Slotted Brake Rotors. This slotted design was created to maximize the out-gassing while maintaining the structural integrity of the rotor. The series of slots and diamond "wipes" the surface of the pad clean, and vent expanding gases which cause brake fade at higher temperatures. The slots also greatly improve wet weather braking by preventing hydroplaning between the pad and rotor. Diamond slot rotors are a unique design in slotted technology that offers styling, performance and reliability. Rotor coating will disappear with time where the brake pads contact the rotor.

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

Quality. SP Performance 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 Slot Anti-Corrosion Finish. Corrosion resistant finishes give a stunning clean look behind your wheels while preventing rust, corrosion and oxidation. SP Performance Diamond Slot Brake Rotors With Gray ZRC Finish: The ZRC coating provides long-lasting protection against corrosion in the most hostile salt-water environments. After being applied, ZRC provides the highest level of galvanic protection. The film of ZRC is conductive. After the coating heats up during use, it bonds permanently to the metal surface. It will not allow the metal to corrode, even when the surface is scratched.

SP Performance rotors provide many advantages like quality, durability, looks and value. But the most important advantage is that your vehicle will stop quicker. Diamond Slot discs provide up to 30% better braking. If, for example, your vehicle takes 30 feet to come to a stop with your stock rotors, then a 30% improvement is equal to 9 feet. During an emergency stop, 9 feet can make all the difference between a safe stop and a dangerous accident. SP Performance is the originator not the imitator. Diamond slotting technology was originally developed by SP Performance. The diamond and slot design was created to maximize the performance while maintaining the structural integrity of the rotor. But don't be fooled, there are many imitators out there. If they are not manufactured by SP Performance then they're not true Diamond Slot Rotors.

Since its beginning, SP Performance® has led the way in the brake industry with its premium-grade performance brake rotors designed to improve your vehicle’s stopping power. With unique innovations and manufacturing techniques, SP Performance has become a leader in its technology of cross-drilling, slotting, diamond slotting, as well as cross-drilling and slotting. Advanced drilling methods put SP Performance brake rotors above the rest in quality, performance, reliability and appearance. The company has developed a drilling and chamfering method that has no sharp edges. SP Performance drills out its rotors with an exclusive sinusoid curved chamfer that promotes cooling, reduces stress, vents moisture and dust, while minimizing heat checking and cracking. Make your vehicle stop like a race car with SP Performance brake rotors!
