The EBC GD7585 is a rear rotor from the manufacturer's GD Sport line, a slotted and dimpled design for the Scion FR-S and its Subaru BRZ twin. The manufacturer says the wide aperture slots draw cooler air under the pad contact area, and it states that GD Sport rotors have much less brake fade. For a buyer weighing this against stock or a plain bargain replacement, the premium pays for better heat management and debris clearing on spirited street use, autocross, or track days, when rear brakes are often overlooked until fade or pad glazing appears. Searches like "FR-S rear slotted dimpled rotor" and "BRZ rear brake fade track day" point to exactly this use case.
Fitment needs checking before you order. Rear rotor type and model-year coverage vary across sources, and user forums report that most US FR-S cars came with vented rears, though some owners describe solid-rear setups, so confirm your car's configuration. Owners on user forums describe a straightforward job: remove the wheel, hang the caliper and pads out of the way, make sure the parking brake is fully released, then ease the rotor off. One owner reused front torque figures on the rear hardware, but verify torque in a service manual.
User forums report that most US Scion FR-S models were equipped with vented rear rotors, but some owners describe solid rears. Check your existing rear rotors or your VIN-specific documentation before ordering, and confirm with the manufacturer if you are unsure.
Owners on user forums report reusing the front-rotor torque figures on the rear hardware. The manufacturer's torque value was not confirmed in this research, so check a factory service manual for the correct rear specification.
This is a comparatively simple rear brake job that a home mechanic with basic hand tools can handle. Owners on user forums suggest starting with the parking brake fully released, since a partly engaged parking brake can prevent the rotor from coming off. If the rotor is stuck, a screw threaded into one of the rotor's holes can be used to push it free. Plan to replace the rear pads at the same time and check the caliper hardware, since the rotor cannot be separated cleanly while the caliper is still in place.
