Dan Cook's Rally Car Cage - Floor and Rocker Reinforcing
This photo shows the rocker and floor reinforcing. A 2"x2"-1/8" square tube is stitch welded to the interior of the car along the floor/rocker intersection. This provides added strength and a place to securely tie the forward down tubes of the rollcage. The center of the floor pans are reinforced with a 1"x2"-1/8" tube that is laid in on its side and welded continuously along the whole length of the floors. Both the driver and passenger floors are reinforced this way.
