The dimple drilled rotor was invented by EBC back in the 90s and has been imitated by many because of its ability to offer pad degassing without "Through Drilling" disc or rotors 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 help remove dirt dust debris and water from the braking area but without doubt 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.
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.For this reason EBC produce 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 is MUCH quieter yet offers similar performance values.
Experience has shown us that on Trucks and SUV the GD or 3GD series wind noise is almost unnoticed and on faster and tuned sedands and hot hatches the GD or 3GD series as we call them (they are both exactly the same item) is the preferred choice.
When replacing rotors of any kind please remember how important brake safety is to your own well being and either have a professional mechanic install your new brakes of if you are a qualified mechanic use the EBC installation DVD as a guide in support of your vehicle owners manual.
