Schroth SFI 16.5 Hybrid II
All harnesses are built to order and ship from Schroth.
In 2007, Schroth introduced the Nextel Cup to the 2" lap belt that has been available to FIA sanctioned racers for years. In doing so, they've stepped up the level of safety available to racers running under all SFI 16.5 harness rules. 2" Lap Belts are now legal in all touring NASCAR series.
The 2" lap belt offers greater safety because it fits better on the human pelvis. The part of the pelvis where the lap belt contacts the body is called the Iliac Crest. This is the bone that sticks out at the front of your hip. When seated, a 3" lap belt will ride on top of this crest. A 2" belt sits below this crest, and exerts all of its force on the hard part of your pelvis, rather than focusing it on a small surface area of bone. Because of this fact, you can generally get the 2" lap belt up to 1.5" tighter than a 3" lap belt.
Add this 2" lap belt to the already impressive features that distinguish the Schroth harness from the rest of the competition and you end up with an easy choice for your harness.
The Hybrid Style harnesses is defined by its special Anti-sub strap setup with two separate straps that loop around the lap belt latches before clicking into the cam lock (See Pictures). This arrangement is much more comfortable for the driver, and is also safer. Generally in tight cockpits, drivers will wear the restraint looser than is recommended purely because a regular Anti-sub strap is uncomfortable. The Hybrid restraint removes the problem, curing the symptom.
You can specify the standard HANS specific 2"/3" shoulder belts or the state-of-the-art "Double Shoulder" belts that feature the 3" body belt and additional 2" HANS belt.
Note: This harness can be converted to 7-point (or 9 point if used with Double Shoulders) By adding a Single Anti Sub strap.
