If you're looking to up your safety game while tearing up the track in your BMW E36, the Schroth Racing Quick Fit Pro Blue RT Belt is a solid choice. This isn’t just any harness; it’s the world’s first 4-point harness designed specifically for use with a HANS Device, and it fits right into your stock seats. That means you can enjoy the peace of mind that comes with enhanced safety without the hassle of aftermarket seats or roll bars.
What makes the Quick Fit Pro stand out? It’s all about the clever integration with your car’s existing safety features. Traditional 4-point harnesses have shoulder straps that are sewn to the lap belts, leaving them too far apart—usually about 6-8 inches. The Quick Fit Pro changes that by angling the shoulder belts towards a central Cam Lock. This design not only maximizes the effectiveness of the HANS Device but also keeps everything snug and secure when you’re pushing your car to its limits.
Installation is a breeze. Just click the harness into your car's female seat belt receptacles, and you’re good to go. This setup not only tells the airbag computer that you’re strapped in but also engages the seat belt pre-tensioner. In the unfortunate event of an accident, this feature ignites a pyrotechnic charge that tightens the lap belt, providing an extra layer of protection. It’s a smart integration that really highlights how well thought out this harness is.
And don’t worry about compatibility—this harness is designed for stock seats that have passed a seat back strength test. So, you can enjoy the benefits of a HANS Device without shelling out thousands for a complete overhaul of your interior. It fits a range of models, including:
In short, the Schroth Racing Quick Fit Pro Blue RT Belt is a game changer for anyone serious about track days or driver’s schools. It’s practical, it’s safe, and it fits right into your BMW without breaking the bank. Give it a shot—you won’t regret it.
