Schroth Profi II ASM 4 Point Seat Belt | Sube Sports

The Schroth Profi II ASM is designed to be used as a four point system in conjunction with a stock OEM seat. For this reason it is perfect for use in High Performance Driver Education (HPDE) cars or any other application where stock seats are retained. A seat that was not originally designed for use with a racing restraint should never be modified to accept a sub strap belt.

The Schroth 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 inboard 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.

The Schroth Profi 2 ASM features 3" polyester webbing at the shoulders and 2" polyester webbing at the lap belts, lightweight adjusters, and a RFR rotary camlock release buckle. The 2" lap belt's notable feature is that it rides within the crest of the human pelvis where a 3" belt would rest on the edges. This allows you to get the belt up to an inch and a half tighter. That means the lap belt will be working earlier in the accident event because it gets loaded faster. It's also more comfortable and easier to adjust because there's less friction through the adjuster.

Another feature unique to the Profi II Series 2" wide lap belts is the "Flexi Belt". The chassis end fittings and Camlock ends are wrapped into the harness, making it so that the lap belt can be changed from a Pull-Up configuration to a Pull Down. This allows you to set the belt up just the way you want it for your specific situation. It also allows for Bolt-In brackets to be wrapped in for the lap belts if needed. Snap in brackets come standard on the laps.

The Schroth Profi 2 ASM 3" shoulders straps come as a wrap around end designed to wrap around a roll bar/harness bar. Snap-In or Bolt-In attachments can be bought separately and inserted into the wrap around ends (as pictured). The lap belts come with Snap-In hardware. Shoulders come in 70" length. SFI 16.1, DOT, and FIA approved. Available in red, blue, black, and silver.
