Tools and Materials Needed

  • Schroth Profi II Racing Harness
  • Socket wrench set
  • Torque wrench
  • Drill with metal drill bits
  • Measuring tape

Preparation Steps

Before starting the installation, ensure you have a clean workspace and all the necessary tools at hand. Follow these preparation steps:

  • Read the manufacturer’s instructions carefully.
  • Inspect the vehicle’s interior for suitable mounting points.
  • Ensure the harness is compatible with your vehicle’s seat and roll cage.

Step 1: Removing the Existing Seat

To install the harness, you may need to remove the driver’s seat. Follow these steps:

  • Locate the seat mounting bolts under the seat.
  • Using a socket wrench, remove the bolts and carefully lift the seat out.
  • Disconnect any wiring harnesses if your seat is equipped with electronic features.

Step 2: Installing the Lap Belt

The lap belt is a crucial part of the racing harness. To install it:

  • Identify the mounting points on the floor of the vehicle.
  • Use a measuring tape to ensure the lap belt is positioned correctly.
  • Drill holes if necessary and secure the lap belt using the provided bolts.
  • Ensure the belt is mounted low on the hips for optimal safety.

Step 3: Attaching the Shoulder Straps

Next, you will attach the shoulder straps, which are vital for upper body support. Follow these instructions:

  • Locate the shoulder strap mounting points on the roll cage or back of the seat.
  • Use the provided hardware to secure the straps, ensuring they are at an angle of 20-30 degrees.
  • Check that the straps are not twisted and are routed properly.

Step 4: Installing the Anti-Submarine Strap

The anti-submarine strap prevents the driver from sliding under the lap belt during an impact. To install:

  • Identify the appropriate mounting point for the anti-submarine strap.
  • Attach the strap securely, ensuring it is positioned correctly.
  • Double-check all connections for security and stability.

Step 5: Final Adjustments

After installation, you need to make final adjustments to ensure the harness fits properly:

  • Adjust the lap and shoulder straps to fit snugly against your body.
  • Perform a pull test to ensure the harness is secured correctly.
  • Reinstall the driver’s seat if it was removed.

Step 6: Safety Inspection

Conduct a thorough safety inspection before your first drive:

  • Check all mounting points for tightness.
  • Ensure that the harness does not interfere with any vehicle functions.
  • Perform a test fit to confirm comfort and security.

Conclusion

Installing a Schroth Profi II Racing Harness significantly enhances safety and power transfer during racing. By following these steps, you can ensure a proper installation that meets safety standards. Always remember to check the harness regularly for wear and tear, and replace it as necessary to maintain optimal safety in your vehicle.
