If you're looking for a harness that blends safety with practicality, the Profi II ASM FE is worth checking out. This version keeps everything you love about the original Profi II ASM but adds a nifty Push-Button Cam lock. Why does that matter? Well, if you're planning to hit the streets, this feature is crucial for staying street legal. It’s a simple red button labeled "Press," but it’s there for a good reason—so that EMTs can easily release your restraint in case of an accident.
One of the standout features of the FE model is the sewn-in, bendable Bolt-In tabs for lap belt attachments. This is a game changer if you're working with tight spaces. Just keep in mind that because of the sewn-in fittings, the Flexi lap belt isn’t an option here. This harness is designed as a solid four-point system, making it a fantastic choice for Driver Education cars or any setup where you want to keep stock seats. A quick note: if your seat wasn’t built for racing restraints, don’t try to modify it for a sub strap.
Now let’s talk about the ASM (Anti-SubMarining) technology. This isn’t just marketing fluff; it’s a unique feature that sets this harness apart. There’s an extra fold of material sewn into the right shoulder belt that stretches differently compared to the outboard belt. This design lets your upper torso twist slightly during an impact, helping to keep you securely planted in your seat instead of sliding under the lap belt when things get rough.
If you’re feeling adventurous, you can easily add a dual sub strap later on to turn this into a six-point harness. We’ve tested it with a HANS device, and it performed beautifully, so you can rest easy knowing it works well in demanding situations.
The lap belts are available only in the Bolt-In style, which is what most folks need for street legality. If you've got a different setup in mind, just reach out to us. You can choose between Pull-up and Pull-down styles, while the shoulder belts are Wrap-In using an LV 7 fitting.
