Venting the gas emitted by hot brake pads improves overall brake performance and helps minimize fade. At one time the conventional wisdom in racing circles was to cross-drill brake rotors to aid cooling and eliminate the gas emitted by brake pads. However, today’s elite teams in open wheel, Indy and Trans Am racing are moving away from crack prone, cross-drilled brake rotors in favor of rotors modified with a fatigue resistant slotting process.
Power Slot’s ProStop rotors were developed to combine the look of a cross-drilled rotor with the durability of a slotted rotor. ProStop rotors are enhanced with a series of drilled “dimples” that look like cross-drilled holes (especially when brake dust is collected at the bottom of the dimples after several hundred miles of driving). By installing ProStop rotors, a driver can have the “look” of a cross-drilled rotor and the performance of a slotted rotor without compromising the structural integrity of the rotor. ProStop rotors with their faux-drilled dimple treatment are specifically designed to provide a safer alternative to drilling crack prone holes through cast iron rotors.
The ProStop slotting process and faux-drilled treatment removes less heat absorbing mass and less of the rotor’s surface area than conventional cross drilling to help maintain the highest possible co-efficient of friction for the brake pads to work against.
Starting with select castings manufactured in Italy and the U. S. , all ProStop rotors are CNC machined to application specific tolerances that utilize a patent pending tapered-slot technology to create a vent for brake dust and pad gasses while preserving rotor strength. The slot designs of ProStop rotors are angled to use the rotors’ direction of rotation to enhance performance. This makes them side specific with left side (driver’s) and right side (passenger’s) rotors.
Brightly-plated ProStop rotors also eliminate rusty rotor syndrome and enhance the look of custom wheels. Their military spec, cadmium plating adds a high-tech appearance and corrosion resistance.
Power Slot ProStop rotors are designed to provide the looks of a drilled and slotted rotor while meeting the challenges of high performance driving and severe duty brake demands. Power Slot ProStop rotors represent one of the most cost-efficient performance brake upgrades offered in the market today.
