PowerSlot slotted rotors for the 08-09 Evo X help reduce brake fade by releasing the boundary layer of gases that can build up between the pad and rotor surface and, consequently, inhibit performance. This is how Power Slot rotors make a big difference in your Subaru’s braking performance: The exclusive Stop Tech Power Slot Vac-U-Slots machined into the rotor “wipe” brake pads clean, evacuate gases, and shed heat from your rotors to provide fade free braking stop after stop.
Stop Tech Power Slot Plus rotors are manufactured to the highest tolerances of safety and quality. Slotting, unlike drilling, will not compromise the structural integrity of the rotor; drilling weakens a rotor and may cause stress points that can lead to cracking and failure.
Drilled rotors also lose considerable surface area compared to slotted rotors, which means a smaller surface area for pad-to-rotor contact. Stop Tech Power Slot rotors are designed using the highest quality OEM replacement blanks. All machining is done in-house to Stop Tech Power Slot’s application specific tolerances to ensure optimum quality control. The final touch is a military-spec cadmium plating that gives Stop Tech Power Slot rotors their bright silver finish and protects the rotor from debris. This eliminates ‘rusty rotor syndrome’ and enhances the look of custom wheels.
