Welding to C5 Hydroformed Chassis
Welding to C5 Hydroformed ChassisI have a manufacturer recommending welding a door bar mount to the rocker area of my C5 frame , says "it can be bolted but the easiest method is welding" looking for educated opinions and/or "been there , done that" has to be able to pass NHRA inspection for "Convertible to 11.50" Can anyone help me on this ? welding a 1/4" piece of steel angle 3 " long to a 3/32" hydroformed frame rail just sounds WRONG to me , not to mention bar was advertised as complete bolt in & NHRA SCCA legal......

as I posted in your OTHER identical thread... there are tons of cages welded into C5's... Nothing "special" about our frames. Yea back in 97 it was a huge deal, but now hydroforming is pretty common in the industry... nothing real fancy about it and the steel is just pretty run of the mill standard HS steel...

Wouldn’t worry at all about the welding.
Either TIG or MIG.
I’ve got the supposed NHRA legal bar in mine as well.
The door bar plates top and bottom through the floor which is balsa wood and fiberglass. Quite ridiculous.
Mine failed tech first time to a real NHRA sanctioned event. They let me run anyway. I race it a lot, they no longer even look at it.
BTW, the NHRA does not endorse anything as being NHRA Legal.
