Very similar to the Profi II ASM but with a buckle that is DOT compliant. The bright red button and "Press" label is what first responders are used to seeing and will save seconds in an emergency situation. Racing harnesses with a cam lock or rotary buckle may cause them to delay undoing the buckle.
For drivers that feel most comfortable using a racing harness in a street car, the Profi II ASM fits the bill. The Profi II ASM is built with ASM technology instead of an anti-sub strap. Using a anti-sub strap on a stock factory seat is almost impossible as the seat was never designed for it (and should not be modified). Schroth's solution is their ASM system, which stands for "Anti Sub-Marining" - a feature built into street harnesses that prevents the occupant from sliding under the lap belt in a crash (submarining).
ASM is an extra few inches of belt that is folded along the inside shoulder belt and hidden under a plastic cover. In a frontal accident the extra belt length is released and allows one side of your body to fall further forward than the other side. This causes your torso to twist, which prevents you from sliding under the lap belt. This also has the benefit of forcing each occupant away from each other. The ASM is on the right shoulder for a driver and the left shoulder for a passenger (in a LHD vehicle).
This harness uses a bolt-in lap belt to meet DOT regulations. A snap-in buckle is not an option. In most cases you can install them at existing seatbelt anchor points. The 3" shoulder straps are wrap-around so snap-in or bolt-in buckles will need to purchased separately if you're using this without a roll bar or harness bar. An additional benefit to this harness is that if you decide to use a racing seat in the future, a sub-strap can be purchased separately and it clicks right in!
Note: "Driver" and "Passenger" are listed for Left Hand Drive vehicles.
