Schroth Profi II ASM 4 Point Harness (Anti-Sub)
Schroth Schroth Profi II ASM 4 Point Harness (Anti-Sub) $399.00
Schroth Profi II ASM 4 Point Harness (Anti-Sub) The Schroth Profi II ASM 4 Point Harness (Anti-Sub) integrates Schroth’s unique ASM (Anti-SubMarining) technology in a four-point system. The ideal harness for stock seats, or seats not designed for a pass-through for a sub strap, that are used in Driver Education programs. Schroth’s ASM is an extra fold of material sewn into the inboard shoulder belt, elongating at a separate rate compared to the outboard belt. This allows two movements: the upper torso can twist slightly, and on the rebound phase, the torso is planted firmly back in the seat instead of sliding under the lap belt. The Schroth Profi II ASM 4 Point Harness is good for use with a HANS device or other Head and Neck Restraint (HNR). The ASM shoulder strap on the ASM is 3” width, which will work with any HNR. A dual or single strap can be added to convert this belt into a 5- or 6- point system. The shoulders are ready to wrap around a roll bar, and snap-in or bolt-in attachments can be purchased. The Schroth Profi II ASM 4 Point Harness also features a “Flex Belt.” Instead of being sewn into the harness, the cam latches and end fittings are wrapped, making configuration changes from a Pull-Up to a Pull-Down configuration quick and easy. In addition to helping you customize the use of your device for your particular situation, you can add bolt-in brackets to be wrapped in the lap belts. Snap-in brackets are standard on the lap belts. Choose from Black, Blue, or Red! Be sure to specify Driver or Passenger side as the construction is slightly different for each. See Schroth Harness Installation Checklist Here

Schroth Porsche GT3/GT4 Four-Point Harness (Anti-Sub)  FITS PORSCHE CARBON SEATS ONLY* Porsche 996/997/991/992 GT3/GT3RS Porsche 981/718 GT4 Porsche 918 DESIGNED FOR YOUR PORSCHE The Schroth Porsche GT3/GT4 four-point harness is designed specifically for the factory Porsche one-piece carbon seats. This harness comes with specific lap-belt brackets that don't require any drilling for installation, as they attach to the factory-engineered lap-belt mounting locations. A harness bar or roll bar are required for installation of the shoulder belts. Schroth's exclusive ASM (anti-submarine) technology on this four-point harness holds the driver’s pelvis snug in case of a crash, preventing “submarining” below the lap belt and sliding out of the seat. With this harness, there’s no need to install a sub-strap mounting bar under the seat, which is also very useful for Porsche passenger seats that don’t have a pre-cut sub-strap slot. The Schroth Porsche GT3/GT4 Four-Point Harness has a street-legal FE Camlock that releases like a traditional seat belt -- just a push of the button! * Designed for Porsche OEM carbon bucket seats. This is not an FIA homologated competition restraint.

Schroth Profi II ASM FE Street Legal 4 Point Harness
Schroth Schroth Profi II ASM FE Street Legal 4 Point Harness $495.00
The Safe, Street Legal 4 Point Harness The Profi II ASM FE is essentially the same as the Profi II ASM, except it features a Push-Button cam lock. The red push button that says "Press" is necessary to retain street legality and so an EMT who shows up at an accident scene will know how to release your restraint. The FE version also features sewn in, bendable bolt-in tabs for the lap belt attachments, for use in applications where space is limited. It's designed to be used as a four point system, perfect for use in Driver Education cars or any other application where stock seats are retained. (A seat that was not originally designed for a sub strap should never be modified to accept one.) The Profi II ASM incorporates Schroth's legendary ASM (Anti Sub Marining) technology that is the only thing like it on the market. ASM is an extra fold of material sewn into the right shoulder belt that elongates at a different rate than the outboard belt. This allows your upper torso to twist slightly. On the rebound phase, your torso is planted firmly back in the seat rather than allowed to slide under the lap belt. You can add a single or dual sub strap to make this belt into a 5 point or 6 point at any time. Schroth tested this harness with a HANS device and the results were great. You can use a 4 point ASM Harness with any HANS device. The lap belts provided with this harness are only available with bolt-in hardware (it's sewn in) as they are most commonly needed in setups requiring street legality. If you need a different setup, please call (844) 438-7244. The shoulder straps come with wrapped-in B23C bolt-in brackets that can be easily removed to wrap around a roll bar or harness bar.
