Rallye 4 ASM

The Schroth Rallye 4 is the de facto standard for anyone looking for a simple, clean, DOT-approved and Safe 4 point harness. The technology built into the harness puts it in a category above the belts made by other manufacturers. The years of testing and motorsport experience only give credit to what the engineers have been saying all along.
There are two main reasons why the Schroth Belts are the only safe 4 point harnesses: ASM technology and the ability to install the belts to stock harness mounting locations.
ASM stands for Anti-SubMarining. It's an extra flap of material sewn into the inboard shoulder belt that prevents you from sliding underneath the lap belt. In a 4 point harness made by some other company, the two shoulder straps restrain your upper body equally. They keep your chest from moving forward. However, this also pulls up on the lap belt and allows your accelerating pelvis to slide under the lap belt and cause serious damage to your stomach and intestines. With ASM, one of the shoulder belts will elongate at a different rate which will force your pelvis down into the seat cushion. Upon rebound, you will be placed back in an upright position with the belt correctly placed over your body.
The advantages of being able to mount an aftermarket 4 point harness to stock mounting locations are many. First and foremost is the knowledge that these points have been load tested. This means that the manufacturer of your vehicle engineered the points to be able to withstand some truly amazing forces for a specified length of time. In plain English this means that the bolts won't pull out of the sheet metal.
It also means (in the case of a Schroth Harness) that you can retain the use of your stock 3-point harness, allowing you the use of the backseat of your car. If you have the need to transport passengers (or cargo) in your backseat, it is possible to disconnect the tailstrap (a feature only Schroth has) and use your normal 3 point harness.
These belts are perfect for Driver's Schools, Autocrosses and canyon runs with your local car club. They offer a comfortable and stylish harness that will hold you in your seat during spirited driving, as well as a restraint that will perform ahead of the competition in an impact.
Available in Black, Blue, Red & Silver.
Please Note: In light of recent testing, Rallye 4 harnesses do not need to be sided. They no longer are specific Left or Right. This harness is not compatible with HANS or any other head and neck restraint devices. This harness is not approved for all vehicles and may exceeded the maximum shoulder strap downward angle recommended by Schroth.
