StopTech Powerslot rotors prevent glazing of the pads, add bite and improve wet and dry braking performance. It’s a fact that venting the gas produced by hot brake pads improves overall brake performance and helps minimize fade
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. Less surface area means less stopping friction which increases stopping distance.
Starting with select castings manufactured in Italy and the US, all Power Slot 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 Power Slot 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.
Additionally, Powerslot Rotors feature a durable black e-coating on the non-swept areas of the rotor to prevent corrosion. The black e-coating is on both sides of the hat, inside the the cooling vanes, and on the outside edge. E-coating is a superior electro-statically applied finish designed to withstand 400 hours of salt water exposure without rusting.
Power Slot rotors are designed to beat the challenges of high performance driving and represent one of the most cost-efficient performance brake upgrades offered in the market today.
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 any products are used on the track they are not warrantable.
