This harness bar kit is a direct bolt in, and picks up the OEM rear seat belt points as well as the suspension points in the boot floor. Made from 5mm steel plate and CDW350 grade roll cage tube, this kit is both strong and user friendly. Requiring no trim modification, this kit can be installed in 60-90min (first time install) with relatively basic tools found in most garages and basic workshops. Standard kit comes powder coated satin black with one eye bolt mounting kit and stepped spacer to complete ALL of the mounting points required to fit your 4 point race harness. The harness IS NOT included in this kit, but can be purchased in addition to. All new harnesses that we have seen on the market come with 25mm 7/16 eye bolts. You will use these eye bolts in addition to the harness bar kit. Should you wish to mount 2x 4 point harnesses (RH&LH) you will need to purchase a second eye bolt mounting kit.

Pictured above is the tools we use when fitting these kits in-house. Tools are listed at the top of this page.

First up is removing most of the rear interior trim to get to the mounting points

Remove the boot floor lining

Remove the boot rear lining

Remove the boot side lining

Remove the rear seat bases using a 10mm socket

Remove the clip hidden by the seat bases that retains the rear side/quarter trims

Slowly pull the side trims away as to not break any of the plastic clips. Holding the front and rear seat belts aside this trim can be pulled forward to expose the rear seat belts. These are the last pieces of trim to come out. Note: We have come across a few cars that have a small tab poking out just above the rear coil-over retaining nuts. If your particular car (dependent on build year) happens to have this tab, it can stop the harness bar end plates from sliding over the coil-over studs. If this is the case, simply push/bend the tabs flat, so that the harness bar end plates slide into place.

Remove the front nuts only of the rear suspension coil-overs. In some cars this tab will need to be pushed flat.

Remove the rear seat belts.

Remove the rear seat belt bracket retaining bolt

Now fit the harness bar end plates into place. Leave the 3 leg bolts loose until top & bottom bolts/nuts are tight.

Fit the rear seat belt back into place.

Fit and tighten the top bolts.

Note the cut out to clearance the wiring loom.

Note the cut out to clearance the fuel filler release cable.

Now start refitting all the interior once ALL of the bolts are tight.

Don’t forget to put this clip back in before re-fitting the rear seat bases.

Refit the rear seat bases

All the boot linings can be reinstalled.

Slide the harness bar into place, lining up the bolt holes.

Slide the harness bar into place, lining up the bolt holes. Once all the bolts are started, go ahead and tighten them.

The harness bar is now fully installed. Now for the eye bolts for the lap belts.

The most common way to fit the eye bolt to the tunnel is to drill a 12mm hole, but drill a pilot hole first.

These plates are as per CAMS spec. The eye bolt comes with your new harness, but can be bought separately.

Showing the rectangle plate under the car in the tunnel.

Remove the front seat belt bolt in the sill at the base of the B pillar

Another eye bolt with the supplied stepped spacer(stepped spacer comes in the harness bar kit)

The stepped spacer allows the seat belt to pivot as it did with the OEM bolt.

Fitting the harness to the harness bar, remove the buckles and wrap around the harness bar.

Finished install

Also available for the Toyota 86/Subaru BRZ is the Trackart bolt in seat mount platform. Available for both LH and RH side, this platform allows the bolt-in mounting of a race seat while keeping the OEM seat belt buckle. Also picking up the crotch strap points for mounting a 6 point racing harness. So no additional holes are required to be drilled in the floor of your car. This seat platform also has an optional fire extinguisher mount. For more details, head to our seat mounting or products pages, or hit the link below. Toyota 86/Subaru BRZ race seat platform
