If you build a steel roll bar use .120 wall D.O.M. or .134 wall R.E.W. tubing . D.O.M. being my first choice "Roll Bars" must be 1 3/4" dia. and not available in .134 wall unless a custom mill run $$$$ "Roll Cages" are 1 5/8"dia and .134 is available in ERW
Thanks for all the input... I just don't want to get to a track and fail tech because I am going too fast for not having a roll bar. Sent from my iPhone using H.A.M.B.
Read the rule book several times, then explain to us what you think the rule book says about your car. We might be able to help you make sure you know what you need to have.
