The Wilwood Forged Narrow Superlite 4R caliper adds radial‑mount capability and two planes of alignment for accurate positioning over the disc. It pairs a compact forged caliper body with 1.38in pistons and is intended to simplify adaptation while delivering big‑brake style stopping power across a broad range of vehicle applications. Radial mounting and Wilwood’s Superlite technology make it suitable for demanding environments where high clamping force and precise alignment are required.
