According to NHRA rules, when you’re running faster than 11.50 in the 1/4 mile or 7.35 in the 1/8 mile, it’s time an SFI-certified restraint system to keep you in place. during a race. Which five point racing harness you choose is important, but what’s even more important is how you fit the belts inside your car.

The basic layout of a five-point racing harness includes a set of shoulder straps, lap belts, and an anti-submarine belt. All of these seat belts work together to keep you firmly and securely in your seat in the event of a crash. The belts need to be installed correctly or they won’t work properly, and this is the last thing you would want to happen if an accident or other problem arises while running on the track.

When you install your belts, they should be mounted in a way that generates enough tension when you tighten them to make sure they can do their job, but it also requires you to mount the belts in the right place. Anchor points should not be flush with a surface – they should be mounted so that the belt can only be pulled in one direction. You also want to be sure that you put the belts in the seat belt adjusters correctly. The image above shows how to thread the belt through the adjuster and properly install an anchor.

The chest and abdominal belts should each be fitted to their anchors within a certain degree range on your body. Impact stroke has excellent documents that you can consult here which indicate how many degrees each belt should be fitted.
