Slotted and drilled brake rotors for cooler brakes
The dimple drilled rotor was invented by EBC back in the 90's and has been imitated by many because of its ability to offer pad degassing without "Through Drilling" disc or rotor holes which has been shown to promote rotor cracks.
The wide aperture slots on the EBC units actually draw cool air under the brake pad and rotor interface and help cool the temperatures of the pad contact which can shoot up to well over 1000 degrees at the very heart of the brake pad during heavy braking and can cause brake fade or loss of brake effect. These "Full sweep" slots on the EBC Sport Brake rotor also wipe away dirt, dust, debris and water from the braking area but the MAIN benefit of such sport rotors is their ability to maintain a flat and parallel pad surface throughout the lifetime of the brake pad set.
One point to consider before making your choice of sport rotor is the air noise that can be noticed with sport rotors. With all slotted rotors there will be an increase in air noise as the rotor passes beneath the pads under normal driving and braking. Some people like this kind of "Turbo" sound and others do not. For this reason EBC produces two ranges of sport rotors, the 3GD or GD series being discussed here are the noisier of the two designs, our sister range the USR sport rotor range which is quieter yet offers similar performance values. Make your choice before you buy please. Experience has shown us that on Truck and SUV the GD or 3GD series wind noise is almost unnoticed and on faster and tuned sedans and hot hatches the GD or 3GD series as we call them (they are both exactly the same item) is the preferred choice. If silent braking with performance on a prestige or quiet car is your target buy then opt for the USR series.
Direction of Rotation of EBC Turbo Groove Rotors
EBC Turbo Groove and Spotty Discs are directional “LEFT and RIGHT” which is nearside and offside of your vehicle. The spotted pattern and the sweeping grooves should be pointing to the rear of the vehicle.
Important Guidelines for Changing Brake Pads and Rotors
Always replace brake pads when replacing rotors. It is false economy to use worn or old pads on new rotors as they can cause hot spots and promote brake fade and more than double bed in time. Doing so is both dangerous and bad economics.
