When it comes to safety on the track, the Schroth SR 91555-8PU 2" Lap Belt Harness is a game changer for serious racers. Originally introduced in 2007 for the Nextel Cup, this harness has been a staple for FIA-sanctioned competitors and is now fully compliant with SFI 16.5 harness rules, making it a top choice for all touring NASCAR series.
The 2" lap belt design offers superior safety by fitting more securely across the human pelvis. Unlike a 3" lap belt that rides on the Iliac Crest—the bone at the front of your hip—the 2" belt sits below this crest, distributing force across a larger area of your pelvis. This design allows you to tighten the belt up to 1.5" more than a 3" belt, providing a snugger and safer fit during high-speed maneuvers.
This harness is engineered for versatility and ease of installation, making it a solid addition to your racing setup. The Formula Style harness features sub straps that feed through D-rings sewn into the lap belts and wrap around specialized hardware on the shoulder belts. This setup is ideal if you're mounting your sub straps to the same locations as the lap belts or if you're sitting on the sub straps, a common practice in single-seat open-wheel cars and among NASCAR drivers.
Drivers have reported significant improvements in safety and comfort with the Schroth SR 91555-8PU. For instance, a 2022 Mustang GT owner noted, "Installing this harness made a world of difference. It holds me securely in place during cornering, and I feel much more confident pushing my limits on the track." Another customer with a 2021 Camaro SS mentioned, "The fit is perfect, and the adjustability allows me to get just the right tension. It’s a must-have for anyone serious about racing."
Whether you're hitting the track or just want to ensure you're secured properly on the road, the Schroth SR 91555-8PU 2" Lap Belt Harness is a top-tier choice that combines safety, performance, and ease of use.
