Drilled/Slotted Brake Rotors

Brake pads fade when the temperature of the material allows gases to "boil" out and create a layer separating the pad from the brake rotor. The holes and slots in these rotors allow the layer to escape thereby keeping the pad in contact with the rotor. The rotor will also run cooler, which helps keep the pads cooler while also reducing the risk of fluid boiling. Note: Pads WILL still fade, and fluid WILL boil if the brakes are used beyond their SAFE capacity. Additionally, drilled rotors tend to crack around the holes due to heat expansion and contraction. Therefore there is no warranty on these parts, and the customer assumes all responsibility for their safe use. All prices are per rotor. Separately drilled or slotted rotors available on request, please call for details.

Stainless Steel Brake Lines

A portion of the "spongy" feel of brake pedals can be attributed to expansion of the rubber flex brake lines. As brake system pressure increases, the lines expand, letting the pedal travel more. These stainless line kits prevent expansion, thereby giving a much firmer feeling pedal. They also do not deteriorate with age. There are two kinds of stainless brake lines; DOT approved lines, which can be used on street cars, and non-DOT approved lines, which are for racing purposes only.
