How much larger in diameter does a tubular bar have to be to have equal strenth of a solid bar?
Does anyone know of a company that offers a 1 3/8" solid front bar? Thanks, Greg




I posted a link to a calculator in your "all thing being equal" post. You can use that to look at the differences in solid vs tubular bars. The big variable in tubular bars is the wall thickness.

If you really want to get in to more detailed bar tuning than what is simply available off the shelf, you may need to look at going to with a splined tube with modular arms. You can find these at http://www.1speedway.com/ or search around for used nascar parts warehouses.

As far as opening up the pass though slot, if you need a larger opening, you just need to stretch them a bit or cut and reweld the adjoining tab.
