Schroth Rallye 4 ASM Racing Safety Harness
Schroth Rallye 4 ASM Racing Safety Harness
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.

Material Selection Guide
We offer 4 materials for our numbers, letters and panel numbers: Magnetic, Reusable Vinyl, Permanent Vinyl and Static Cling. They are designed for use on different types of cars and for different kinds of use
Magnetic
Magnetic material is the most durable removable product we sell. It works well for application on steel bodied cars at speeds generally below 70 MPH. It can be used for higher speeds, but may have a tendency to blow off. We recommend testing to see if your car is magnetic using a fridge magnet or something similar prior to ordering.
PROS:
- Durable
- Lasts decades.
- Easy to clean
CONS:
- Can lose flexibility in cold weather (should be put on hood in sunlight to warm up when using at events under 45 degrees)
- Limited to approximately 70mph. If using at speeds higher than this, it is recommended to apply a small piece of tape to the leading edge to avoid blowing off.
- Does not adhere to fiberglass, plastic, glass, or aluminum
Reusable Vinyl
SOLOTIME reusable vinyl products allow you to apply temporary numbers to your car and reuse them event after event. The material is extra thick* which helps prevent tearing or stretching the numbers when they are removed.
The low tack adhesive numbers come on a paper backing that allows you to store them between events.
PROS:
- Adheres to any smooth surface (including windows)
- Will stay on at any speed.
- Works in any temperature.
CONS:
- Must be put back on backing paper in between uses.
- Must be put on a clean car and adhesive must be kept clean.
- Typical users get between 6-18 uses.
* about 8-12mils, compared to 2-3 for a regular decal.
Permanent Vinyl

"Permanent" vinyl material is your typical vinyl that any pre made decal or sticker would be made with. It can be removed, but will be destroyed in the process of removal. The permanent vinyl is a high quality 5-7 year rated outdoor material.
PROS:
- Very long lasting.
- Will stay on at any speed.
CONS:
- Cannot be removed without destroying
Static Cling
Click for the static cling installation instructions.
SOLOTIME static cling products are autocross tested and work well for low speed events. These products cling to most smooth surfaces, such as fiberglass, plastic, steel, or aluminum. They even cling to glass!
Each static cling number or letter comes with a special paper backing that keeps them ready for the next autocross event. Note: Please test these numbers on your vehicle before you use them at a racing event.
Unlike strong magnets or adhesives, static cling products may blow off your vehicle during unusual racing or weather conditions. We recommend that you order extra numbers as a precaution.
- Inexpensive
- Works on any smooth surface
CONS:
- Must be applied very carefully.
- Comes in white only and is not available as a base for panel/meatball numbers.
- May come off during wet events.
