Overview

OMP Racing 4M Racing Harnesses

The 4M Series from OMP consists of performance-oriented 4-point racing harnesses designed primarily for tuning, autocross, and track day enthusiasts. These harnesses are engineered to provide significantly more support than a standard 3-point seatbelt by minimizing body movement during high-speed maneuvers. The 4M Series two primary variations are the Racing 4M and Road 4M—which differ mainly in strap width and intended use. Both models use a central push-button release buckle, similar to a standard road car buckle, for ease of use compared to a professional camlock system. Select the harness model you'd prefer.
