If you have a competition-style seatbelt setup with 3 in. shoulder belts, you'll want R.J.S. harness pads. They're available in several colors and slip neatly onto the belts for easy installation and a professional look. The important thing, though, is that they help to cushion any impacts in the event of a crash. An extra-added benefit is that they also protect your driver suit from abrasion.
