Ford Performance Rear Seat Delete & X-Brace

This rear seat delete was standard equipment on the 2012 and 2013 Boss 302 Laguna Seca racecar. It obviously deletes the rear seat, helps improve chassis rigidity, and you even shave a couple of pounds. Which, when it does come to racing, every last pound saved helps out tremendously.

It will feature carpeted trim panels and a gray powder-coated x-brace, and the biggest feature to me with this kit is that there is zero cutting or welding required. Also, since it was a factory option on those Boss Laguna Secas, you don’t have to worry about improper fit.
