Yes, I went with much thicker front and rear bar after that rollover. I had just come out of some S-turns and was turning sharp right. The front jacked up thru the S-turns and the front tire hit a divot and olly-oops...
Using a very heavy bar in front is to try to prevent jacking up of the front suspension, and the heavy rear is to help swing the ass end around when needed. It is pretty rough ride. The aluminum seat is bolted directly to the cage, and there is minimal cushioning. About 3/4" of closed cell foam.
