My goal is to use an sae style buggy as my design. I plan to have a complete Z400 front end and an IRS rear using early 80's vw type 2's with inboard pucks and a 6 spline center.
My brother is twisting my arm pretty hard to use a solid axle rear and not IRS. Either way I should be around 500 pounds and 50 HP give or take a little.
We ride eastern indiana or southern ohio, tight woods, generally under 30 mph but beat the snot out of our current rides. I thought the larger diameter would offer more strength but you really have me thinking about the welding aspects of .095.
Both tubes imention are pretty much the same wieght per foot so no gain or loss there. A little more meat to weld on would be nice. DOM is nearly twice as much as ERW, would you have a huge prefference there ? And I fully understand the differences but would ERW be good enough is more the question.
