This is Hawk's DTC-60 race compound in a rear set, sold for the Mustang 5.0L GT and Shelby GT500 platform named in the product title. The G in the part number is the compound code that Hawk's DTC-60 motorsports pads also use. Owners on user forums report that Hawk's track program pairs DTC-70 fronts with DTC-60 rears on the 2020-22 GT500, a front/rear split used to balance bite between axles. That makes the DTC-60 a better choice than stock pads for a car that is driven hard on a track, where the stock pads may fade.
Fitment is the first thing to check. Model-year ranges in listings vary, so confirm the application by VIN with the manufacturer before ordering. For DIY work, the rear calipers on the Bullitt (a 2008-09 Mustang in this family) need a piston reset tool, because a C-clamp will not push the piston back, and a special piston reset tool that turns the piston back into the caliper is required. Owners say it should take less than an hour to replace the pads.

Owners on user forums report that the rear pistons on this platform will not retract with a standard C-clamp and need a piston reset (wind-back) tool.
Owners on user forums pair DTC-70 fronts with DTC-60 rears on GT500 track builds. The manufacturer's guidance is to follow the vehicle-specific installation instructions.
The manufacturer's general bed-in procedure calls for moderate stops from about 30-35 mph, a few hard stops from about 40-45 mph, no dragging of the brakes, and a full cool-down before racing. That procedure is written for street pads, so confirm the race-pad bedding steps with the manufacturer.
Plan on about an hour per wheel with a jack, jack stands, and a piston reset tool. Owners on user forums warn that the rear caliper must be supported so that the brake hose does not stretch or crack. Clean the caliper bracket and slide pins, and apply grease only to the pad ears, not the friction surface. Then bed the pads following the manufacturer's procedure, and do not engage the parking brake on hot rotors.
