It’s a fact that 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.

IMPORTANT REMINDER: Slotted, drilled or dimpled rotors offered as OEM replacements should not be considered appropriate for high-speed track use.

While grooved, drilled and slotted rotors offer an enhanced appearance and add some resistance to the boundary layer of gasses that can build up between the pad and rotor, they are not designed to withstand the extreme temperatures that are produced on the racetrack. If they are used on the track, it is very important that the rotors be carefully inspected and should not be driven on if even minor signs of deterioration are seen. Note, too, that if these products are used on the track they are not warrantable.

ProStop Brake Rotors

It’s a fact that 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 rotors bring this technology to the street and are specifically designed to run cooler, promote dramatically improved wet and dry brake performance, and are a safer alternative to drilling crack prone holes through cast iron rotors.

The Power Slot slotting process removes far 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. Slotted rotors trade only 3. 7% of their surface area to the slots that vent the gasses, while drilled rotors sacrifice up to 7. 75% of their surface area, and rotors that are both drilled and slotted sacrifice up to 9. 38% of their surface area. Less surface area means less stopping friction.

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 II rotors were developed to combine the look of a cross-drilled rotor with the durability of a slotted rotor. ProStop II rotors are enhanced with a series of four 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 II 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 II rotors with their faux-drilled dimple treatment are specifically designed to provide a safer alternative to drilling crack prone holes through cast iron rotors and offer a more aggressive appearance than the original ProStop rotors.
