There are two major types of high-performance brake rotors -- drilled and slotted. We'll discuss the drilled rotors here and move on to the slotted rotors on the next page. 

Drilled Brake Disc Feature Performance Brake Disc

Drilled brake rotors, as the name implies, have holes drilled in them. Having a holes drilled into any of your brake parts may seem counterintuitive, especially the brake rotors -- after all, a rotor full of holes means that there's less surface area for the brake pads to grab and stop the car -- but there are a few reasons drilled rotors make sense.

The first is heat. When the brake pad grabs the rotor, it creates friction, which creates heat. If that heat can't escape, it leads to brake fade, which reduces the brakes' stopping power. The second reason is gas build up. This actually isn't much of a problem any more; however, the materials used in some older types of brake pads caused gas to build up between the rotors and pads. That gas also limited stopping power. The last reason is water. If a car drives through a puddle, a carwash or even a rainstorm, the brake rotors can get wet. A wet brake rotor is slippery and difficult for the brake pads to grab. Having drilled holes on a brake rotor makes it easy for heat, gas and water to be quickly moved away from the rotor surface, keeping the brake performance strong.

The downside of using drilled rotors on your vehicle is that all of those holes tend to weaken the rotors -- just like punching holes in the wall of a house would weaken the wall. After repeated stressful driving, the rotors can even crack.

Holes are drilled through the rotor to dissipate heat. Cross drilling is very effective for heat dissipation. It will prolong the life to the pads, rotors and improve stopping power. It also shed off water under-wet driving condition.

Cross-drill and slot patterns are precisely CNC machines for perfect fit to OEM specs for use with OEM calipers and wheels so that no upgrades are needed. Cross-drilled and slotted rotors give the maximum braking performance under all necessary driving conditions. Precision machined holes or slots on the rotors will allow hot gases from brake pads to escape quickly to prevent skidding or locking up. The quick response from pads to rotors will allow for improvement in stopping power.

The World-wide Harmonized Test Procedure for Light Duty Vehicles

The World-wide Harmonized Test Procedure for Light Duty Vehicles

In order to assess vehicle performances in terms of criteria compounds, CO2 emissions and fuel/energy consumption,laboratory tests are mainly carried out. During these tests a vehicle is driven on a chassis dynamometer (which simulates the resistances the vehicle encounters during its motion) to follow a predefined test-cycle. In addition, all the conditions to run a test must strictly adhere to…
