Summit Racing™ offers Extreme Performance coated brake rotors for thousands of vehicles, from the 1960s and up. They're manufactured on CNC machines using CAD-CAM design for perfect balance and alignment, then coated with silver zinc to resist corrosion. These rotors provide you with maximum stopping power, reduced warping, and longer life. The cross-drilled holes and slots provide an exit route for gasses and dust, resulting in better heat dissipation and less brake fade under hard use. Other solid-surface rotors allow gasses to create a cushion between the pad and the brake rotor, resulting in poor brake performance. The cross-drilled holes and slots clear away harmful gasses, restoring full pad-to-rotor contact. These coated rotors are a terrific performance upgrade when replacing your brakes. Order the model recommended for fitment on your vehicle.

Mopar and Hemi mean a lot to car guys--they embody power and classic design. Summit Racing™ Mopar Hemi coil-on-plug ignition coils are a great way to match well-engineered engines with the pure power of plasma. We use pure copper wire, rare earth magnets, and a custom primary and secondary wind to provide 20 percent more voltage and 30 percent more spark energy (mj) over stock. All this comes from a stock-sized coil housing. They fit in the stock location, making changing these coils as easy as possible. If you are running a supercharger, turbocharger, nitrous, or are burning E85, you need the hottest and strongest spark possible to burn your fuel. With the increased voltage and energy output values, your cylinders will get the spark they need to maximize fuel burn!
