Wilwood DynaPro rear brake kit for Subaru Impreza WRX brings forged billet four-piston calipers and BP-10 compound pads to the rear axle while retaining full OE parking-brake operation. Rear rotor and hat combinations are engineered per vehicle to ensure precise fit with the DynaPro calipers, and caliper piston sizes are chosen to provide balanced rear bias using the factory master cylinder, offering a complementary upgrade alongside front big brake systems.
