I don't have tubular, but do have a set of new reinforced steel A-Arms used for racing.
Support added and welded to barrel section, as well as sway bar mount area.
Welded such that the barrel and sway bar area are much stronger, yet allow the A-Arms to deform with a severe hit, and not transfer all the force/energy to the aluminum cross member, and/or punch out the top of the McPherson strut.
