Slotted & Drilled Rotors

At Globe Tire & Motorsports, we help our customers in Los Angeles, CA, Glendale, CA, Beverly Hills, CA and surrounding areas understand the benefits of upgrading from stock rotors to drilled and slotted rotors. We sell and install drilled and slotted rotors on request.

Quick Facts About Slotting & Drilling Rotors:

In racing, weight is everything and slotted or drilled rotors are slightly lighter than a stock rotor.
The practice of slotting or drilling rotors is technology that was developed from racing to reduce weight and stopping distances.
The minimal weight savings will make very little or no difference in the braking performance of a heavy road vehicle.

Drilled or Slotted Rotors VS. Stock Rotors

Drilled or slotted rotors have more grip. Stock rotors do not have as much of a grip.
Holes or slots help air ventilation and expel heat. Rotors will run cooler and cool off faster. Stock rotor will over heat sooner and stay hot.

Additional Benefits Behind Upgrading to Drilled & Slotted Rotors

Slots increase brake pads bite: There's a misconception that slotted rotors will heat up because of the added grab and the rotors will ultimately over heat. This can be true under repetitive use, such as on a racetrack or slowing down a heavy load down a steep hill, and the rotors do not have enough time to dissipate the heat. When there is too much heat, the increased bite provided by the slots will raise the brake pad temperature slowing down the vehicle sooner, thus you don't need to apply the brakes as long.
Holes and slots reduce wear: The misconception also exists that the slots and holes will wear out the pads sooner. This can be true if you use less expensive brake pads that have a low working temperature. For every 100 degree increase over the pads operating temperature, the pad wear doubles. For example, if the pads can only withstand 300 Degrees and your brakes are running at 400 degrees, then the pads will start to wear quickly. If you purchase a set of performance rotors you need to also purchase a set of high performance pads. This will insure longer life of both rotors and pads.
