Munk's Motors - Parts Review CROSS-DRILLED NEUSPEED continues to set the pace in import performance with its line of cross-drilled rotors. Each rotor receives an engineered hole pattern designed to achieve maximum cooling, safety and minimum brake pad wear. All machine work is performed on a CNC milling machine to a precise pattern, so you get a product with the highest quality. We eliminate the sharp edges from ordinary drilling, which causes rapid pad wear by using a special tool that makes a radius on the outer edge of the hole. The bottom of this radius also denotes the wear limit of the rotor, so you can easily check on its condition. SLOTTED The patented asymmetrical design on NEUSPEED's slotted rotors is engineered to relieve hi-temp gas build-up between the pad and rotor under the hardest braking conditions, without sacrificing the structural integrity of the rotor. The gas slots are CNC machined to a specific angle and length. With less heat build-up, your pads and rotors will last longer and will be less likely to fade when you truly get on the brakes. The NEUSPEED slotted rotors are perfect for your racing applications as well.
