If you're someone who enjoys both the thrill of the track and the comfort of street driving, the Schroth Quick Fit Harness SR 16665-0 might just be the solution you're looking for. This harness is designed specifically for those who want a reliable safety option without compromising on everyday usability.
The Quick Fit Harness anchors to factory points in your vehicle, ensuring stability and safety without the worry of it tearing away during use. The factory points are rigorously tested to withstand a force of up to 3,000 pounds for 6 seconds, providing peace of mind on both the street and the track.
One standout feature is the ASM (Anti-Submarining Mechanism) technology. This keeps the lap belt positioned low, preventing it from riding up and causing discomfort. As one customer put it, “I used to dread the lap belt digging in during hard turns, but this harness keeps everything in place perfectly.”
Additionally, the harness utilizes your vehicle's factory seat belt pre-tensioner, which tightens the belt by 1-2 inches in the event of an accident. This means that your airbags will deploy as intended, providing optimal safety during a collision. A user noted, “It feels like I’m actually strapped in properly, and I trust that the airbags will work as they should.”
The Quick Fit Harness is designed for easy removal, allowing you to use your car for everyday tasks without hassle. It’s a practical choice for those who need to carry passengers or cargo without permanently installing a racing harness.
These harnesses are intended for use with stock seats that have passed a seat back strength test. They are not approved for use with fixed back or aftermarket seats, except for the Cobra Nogaro and Recaro Pole Position ABE models in already approved vehicles. Please note that this harness is not compatible with HANS or other head and neck restraint devices. If you require compatibility with a HANS, consider the Quick Fit Pro version instead.
