I’ve decided to delete the rear seat and add a harness bar to compliment some new Corbeau RRX seats. I took some pictures along the way to document the fabrication. It is a bolt in unit to receivers that are welded to the upper rear shock mount pads. I can do this because of the C4 suspension that is in my car, which eliminated the Camaro rear shocks. I hope you enjoy it.

Receivers for the cross bar

Cross bar mock up

The carpet will cover the receivers like the original foam fillers

Lower down bar brackets bolt to the rear seat belt pad

Mock up of the rear outriggers. There are pads welded to the rear deck.

Rear half of the unit tack welded in place

The harness bar will “float” just behind the seats at shoulder height with the attachment bars centered to evenly transfer the load to the cross bar.

Down bars added to transfer additional loads to the floor.

 

Looks to be another well engineered & functional piece for your already amazing car. It also adds visual interest to the interior, giving a hint of what lies beneath. The bar, harnesses & Corbeau's will look great together. Have you settled on a brand of harness yet?
Seeing the interior makes me ask, did you discuss the interior coatings somewhere? It looks to be "Lizard Skin"? And I am very interested in how you wired your remote battery.
Great work!

 

I will probably use the 3” Corbeau belts, but I haven’t given it much thought. The car will be mostly street driven with occasional auto cross and open track days, which do not require dated belts. I did use Lizard Skin coating on the inside, heat barrier on the firewall, transmission tunnel, and roof with sound control throughout. The battery relocation is nothing exotic, fairly standard stuff. 1 gage for both power and ground on the right side. The 1ga power is for the starter only and the 1ga ground is bonded to the chassis in four places. A 4 gage charge wire from the alternator back to the battery on the left side. There is a power distribution pass through block on for firewall next to the the C100. There is a panel in the spare tire well with a start solenoid, fuel pump relay, and fuel pump fuse. I would do a separate write up if there is enough interest, but it has been covered in depth by many other members on this board.
