Question:

I have a Chevy S-10 that I’m building to go E.T. Racing at my local NHRA track.  I think it will run in the low 11-second range and I know it will need a roll bar.  It has the original floor and firewall.  My question is can I put the roll bar on 6” X 6” plates welded to the floor?

Answer:

Roll Bar Ronnie,

No, all vehicles with OEM frame, such as an S-10 must have 1 ¾” roll bar welded or bolted to frame; also the installation of frame connectors on unibody cars does not constitute a frame.
