i got a quick question for the two seater rx7 that has the storage boxes in the back how do you install a racing harness ive put them in other cars that had rear seats but do you have to drill to put them in thanks.

 

Roll bar or make a harness bar that is welded to the B pillars.

 

cool thanks for the reply man

 

do not use harnesses without a roll cage. if the car flips and crushes the roof, it will either snap your head off or crush your skull as there is no where for your body to go.
