G-FORCE Tuner Belts are harness sets perfect for rallies, lapping days, autocross events, and show cars with most stock or aftermarket seating systems. Made of soft-weave PolyTeck webbing, they help keep you secure and your responses tight. Don't worry about bracing yourself as you sling your tuner into a sharp turn-stay in place with these harnesses. They can be fabricated into all seating locations and offer both the passenger and the driver a crisp, enjoyable ride. These harnesses come with a quick-snap locking buckle and quick-release tabs for easier adjustment.
