The Wilwood Narrow Superlite 4R rear kit in red uses forged four-piston calipers, BP-10 compound pads, and 12.88-inch rotors to improve rear braking for 2008–2012 Subaru WRX applications. These FNSL4R kits are engineered to preserve OE parking brake, master cylinder output, and ABS function, offering a matched aesthetic and braking performance alongside larger front brake upgrades and wheel, tire, or suspension changes.
