Safety Check: Is your harness actually doing its job?
Whether you’re prepping for your first event or you’ve been on the grid for years, harness and FHR setup isn’t an arbitrary task. Using guidance from Motorsport Australia and harness manufacturers, here’s what you need to get right when installing and setting up your harness. For more detail, see Schedule I in the Motorsport Australia Manual - Technical Appendix.
1. Use the Hardware.
Harnesses must be mounted using properly rated eye bolts, or wrapped around a harness bar or roll cage. Make sure you use either the stock seatbelt mounting holes, or a properly-sized reinforcement nut plate when mounting to the body. All of this hardware is readily available from any motorsport parts shop.
2. Watch the Angles.
Ideally, your shoulder straps should mount between 0° and 20° below the horizontal, though Motorsport Australia allows up to 45° below the horizontal as a not-recommended worst case. Set the shoulder strap lengths so that the adjuster buckles are just above the bottom of your FHR, or around the height of your ni***es if you're not wearing a FHR.
3. Keep it Narrow.
For FHR users, your shoulder anchors should generally be closer together than the width of your neck (roughly 100-150mm apart). This keeps the belts locked onto the device so they don't slide off your shoulders mid-corner.
4. Through the Slots.
Your belts must pass through the seat's designated harness holes, not over the side bolsters or the top of the headrest. If the belt isn't in direct contact with your body, it can't hold you in the seat.
4. Lap Belts First.
Always buckle up and pull your lap straps tight across your pelvis before you touch the shoulder adjusters. If your lap belt is sitting over your stomach, you’re at risk of "submarining" under the belt in an impact.
Take five minutes in the shed this week to check your mounting points and straps. Scrutineers will be checking, but more importantly, you want it right for your own safety.
