Weird how this got all off-topic-

Cusco cages are death traps. If you end up on the roof, I can almost promise you the S-bend downlegs will fold like an accordian. The mounting tabs for the rear downlegs are crap too.

As far as race seats, I would NEVER take to the track in a reclining seat. I am also not a fan of bottom mount Sparco type seats, nor of the cool new aluminum "seat mounts" for them that seem to be floating around these days. Kirkey is the way to go, nice and light and comfy. Work perfectly

Now as to legal for drifting or whatever, the Drift event organizers know full well that requiring the average idiot to put a cage in thier car will kill thier entry numbers, so they skirt the ragged edge of safety.
