We were going about 50 MPH. The trailer pounded it a least one good time. It was a stock roll bar, with a 1.75 .120 wall HREW front kit from M.O.R.E. See the bent HREW in the pic. Everything else done by me is .120 DOM which didn't bend it just contorted at the welds. The whole top of the cage shifted over about 8 inches, the bottom just bent with all six frame mounts attached solid and in good shape.
Heres a shot of the cage, any input about how it could be built stronger would be great. It also has 4 horizontal bars, one windshield, one for the five points behind the seats and two spanning the floor. I guess it was just fast and I'm lucky it held up that good at all.
