If you're looking to add some serious safety to your ride without sacrificing comfort, the Schroth Racing Harness P2 4 ASM Flex Snap in Red LT is definitely worth a look. This isn’t just any harness; it’s built for those who want to keep their stock seats while still getting that racing feel.
The Profi II ASM is a four-point system that really shines in Driver Education cars or any setup where you’re sticking with the original seats. Just a heads up: if your seat wasn’t meant for a racing restraint, don’t try to modify it for a sub strap. It’s not worth the risk.
One of the standout features is the ASM (Anti-SubMarining) technology. This isn’t your run-of-the-mill safety feature. The ASM has an extra fold of material on the inboard shoulder belt that stretches differently than the outboard belt. What does that mean for you? In a hard turn or sudden stop, your upper body can twist a bit, but when it’s time to settle back into the seat, you’re held securely instead of sliding under the lap belt. It’s a game-changer for keeping you where you belong—firmly in your seat.
Another cool aspect is the Flexi Belt design on the 2-inch lap belts. Depending on your preference, you can switch from a Pull Up to a Pull Down configuration. This flexibility means you can set things up just right for your driving style. Plus, if you need to, you can wrap in Bolt In brackets for the lap belts. The standard setup comes with Snap-in brackets, making it easy to install.
The shoulder straps are ready to wrap around a roll bar, and you can grab separate snap-in or bolt-in attachments if you need them. Just make sure to install the ASM correctly—it's designed to be on the inboard shoulder belt, so pay attention to that. And if you’re looking to switch up the cam locks, you can snag a street legal FE Push Button cam lock separately.
In short, the Schroth Racing Harness P2 4 ASM Flex Snap Red LT gives you the safety and adjustability you want without complicating your setup. Whether you’re hitting the track or just want a little extra peace of mind on the road, this harness has got your back.
