Roll Cage, Phase 0: It arrives

Posted by Tom Hampton , 01-23-2011 · 1,576 views

Okay! Iâ€™m excited. The roll cage kit has arrived from Advanced Autosports. Itâ€™s a complete weld in kit including NASCAR style door bars. It comes with all the bent parts (main hoop, sides, harness bar, windshield bar, and door bars) as well as precut straight pieces, and steel plates to act as footings. I like the AA cage for several reasons:

It maximizes the allowed steel for footings.
The footings are also extended into the rocker-panel, and the cage tubing can actually be welded to the side and footing for a VERY strong landing
The harness bar is directly inline with the door bars. This helps to transfer the load from a door impact across the cage rather than into the driver.
The cage comes with a knee bar that runs through the dash. This is at the height of the bumper, so that if someone hits the door, again the load is transferred away from the driver.
The cage is made of 1 5/8â€ DOM 0.095 wall mild steel. Slightly larger than required, and a little stronger as a result.
