If you’re serious about getting your ride track-ready or just want to make sure you’re safe while having fun, the Schroth Racing Harness P2 4 FE ASM Bolt PD Blue LT is worth a look. This harness is a step up from the standard Profi II ASM and comes with a nifty Push-Button Cam lock. Why does that matter? Well, if you’re planning on hitting the streets, that bright orange button marked “Press” is crucial. It ensures that in the unfortunate event of an accident, first responders can easily release your harness without any hassle. Safety first, right?
Now, let’s talk about fit. The FE version has sewn-in Bolt-In Tabs for the lap belt, which is a game changer if you’ve got a tight space in your car. Just a heads-up: since it comes with these built-in fittings, you won’t find the Flex Belt lap option here. This harness is designed as a solid four-point system, making it ideal for Driver Education vehicles or any setup where you’re keeping those stock seats. Just remember, if your seat wasn’t built for racing restraints, don’t try to modify it for a sub strap—better to play it safe.
What really sets the Profi II ASM apart is the legendary ASM (Anti-SubMarining) technology. This isn’t just marketing fluff; it’s a smart design feature that adds an extra fold of material into the inboard shoulder belt. What does that mean for you? It allows your upper body to twist a bit during a crash, which keeps you from sliding under the lap belt on rebound. Instead, you’re firmly planted back in your seat, which is exactly where you want to be when the adrenaline starts pumping.
So, if you’re looking for a harness that combines safety, comfort, and a bit of street cred, the Schroth Racing Harness P2 4 FE ASM Bolt PD Blue LT has got your back—literally.
