The perfect street-to-track harness system


The SCHROTH Rallye 4 ASM Harness is the go-to standard for anyone looking for a simple, safe and effective, and DOT-approved 4-point harness. The technology built into the harness puts it in a category above any belts made by other manufacturers. The years of testing and positive motorsport experience and accolades give credit to what the Schroth engineers have been saying all along. There are two main reasons why the Schroth Belts are the only safe 4-point harnesses: 1) ASM technology and 2) the ability to install the harnesses to stock mounting locations.


Schroth's ASM, or anti-submarining, technology features an extra flap of material sewn into the inboard shoulder belt that prevents you from sliding underneath the lap belt in an accident. 4-point harnesses made by other companies have the two shoulder straps restrain your upper body equally in an impact. While that may keep your chest from moving forward, it 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 the highly-regarded ASM system, 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.


There are several advantages to mounting the Schroth 4-point harness to your stock mounting locations. First and foremost is the knowledge that these points have been load tested. This means that BMW has engineered the points to be able to withstand incredible forces for a specified length of time. In the event of an impact, this means that the bolts won't pull out of the sheet metal. With the Schroth Harness, it also means that you can retain the use of your stock 3-point harness, allowing you the use of the backseat of your car. Schroth's tailstrap design makes it easy to quickly disconnect the harness and while use your standard 3-point belt when you need to transport passengers or cargo.


These belts are perfect for driving schools, autocrosses, and even spirited canyon runs with your local car club. They're comfortable, look good, and they'll hold you in your seat during any sort of high-performance driving. Plus, they work incredibly well as a restraint that will perform well ahead of the competition in an impact. 


This belt will work perfectly for vehicles on the reference list, as it is critical to test the seat back strength in order to make sure the seat can withstand the forces exerted upon it.


Available in black, blue, red, and silver. Harnesses fit either side of your car. Universal fit for all models, including newer cars with no Schroth Quick Fit applications.
