The Wilwood Narrow Superlite 4R rear kit for 2000–2006 BMW M3 (E46) pairs forged four-piston Narrow Superlite 4R calipers with 12.88" rotors and BP-10 compound pads to complement larger front brake upgrades. These kits retain OE parking brake function, master cylinder output, and ABS where used, providing matched rear braking performance and optional finishes to suit show and high-performance street builds.
