The Wilwood Narrow Superlite 4R rear kit features forged four-piston calipers, BP-10 compound pads, and 12.88-inch drilled rotors to improve rear braking and appearance for 1999–2005 Subaru WRX and 1999–2007 Impreza applications. These kits maintain OE parking brake function, master cylinder output, and ABS compatibility, and provide a matching aesthetic and braking balance alongside larger front brake upgrades and wheel or suspension modifications.
