The EBC GD7706 is a front rotor set from EBC's GD Sport line for the Ford Focus ST, built with a dimple-drilled and wide-slot design. The manufacturer says the dimples let pad gases escape without through-drilled holes, which it links to rotor cracking. The GD series is machined in the UK from R90-approved blanks, and each rotor is runout-checked and balanced before release. Compared with stock discs, the wide slots help the braking surface clear pad dust and heat during repeated hard stops, which is the practical case for paying more on a track-day or spirited-driving Focus ST where fade is the limiting factor.
Fitment is the first thing to check. The GD7706 is listed for 2013–2018 Focus ST models with a 335mm front rotor, but that rotor size is associated with later-build cars, so confirm your build date with the manufacturer's fitment tool before ordering. Installation is a standard front brake job: lift and support the car on jack stands, remove the wheel, unbolt the caliper and hang it clear of the hose, remove the bracket, and clean the hub face before seating the new disc. Searches such as "Focus ST 335mm dimpled slotted front rotors," "GD Sport rotors track day Focus ST," and "EBC GD7706 front brake upgrade" match this part.
Fitment is listed for 2013–2018 Focus ST models, but the 335mm rotor size is tied to later builds. Confirm your car's build date with the manufacturer before ordering, since fitment data for early ST models varies.
The manufacturer says dimple drilling lets pad gases escape without through-drilled holes, which it associates with rotor cracking. The dimples are designed to keep the rotor's structure intact.
This is an intermediate-level front brake job that most home mechanics can complete with a floor jack, jack stands, a socket set with a torque wrench, a wire or bungee to hang the caliper, and brake cleaner. Replace the pads with the rotors, since worn pads will not seat properly on new discs. Use a wire brush or scraper to clean rust and debris from the hub face and the rotor's mounting surface, because poor contact there can cause runout and vibration. Torque the lug nuts to the factory specification in a star pattern, and bed in the new pads and rotors with a series of moderate stops before any hard track use.
