Bolt-In Autopower Street-Sport Harness Bar - Behind Bars

Again, Dave used a center punch on the floors. This helps align the drill so it doesn’t try to walk out while he’s trying to open the hole.

Here are the mounting plates for the main rollbar hoop and lap belts from the harness. Note how large washers and fairly wide plates are used to more widely distribute the load placed on the floorpan (The eye-bolts for the harnesses are very long so you may want to cut them shorter.)

We popped every trim panel back on and took a break to survey our work.

As suggested by Rick White at Autopower, the shoulder harness straps were fed through the headrest. (If you don’t have a headrest that looks like this with dual adjustment bars, you should invest in a proper racing seat to align the shoulder straps correctly.)

The installation is complete and I now have four-point harnesses to keep me in place when I hit the track. And we retained full functionality of the factory seatbelt system for the street. I had a chance to test the harness out at a race and was very surprised by how well the four-point held me to the factory GTO seat. This gave me more confidence and allowed more focus on driving.
