I paid a friend with a MIG welder to do the welding on my new Spohn SFCs. He said that even though the directions say to weld every 6" the whole way, he didn't see the point of welding to anything besides the frame (so he didn't) and was afraid he'd light the body on fire.

I know you can do it w/o lighting the carpet on fire (hello, pull back the carpet?), but What are the pros/cons of welding Spohn's sfcs to more than just the frame rails? Is it pointless not to do so?

 

other than more time and effort there are no cons, you'll get more strngth and a more solid connection if you weld them to the floor pan or the edge of the rocker panel

Moderator. Is correct! Install them exactly as the instructions say. They really aren't going to do you much good unless they are welded to the rocker panels, and floor pan. When I had mine installed. I simply pushed a big (and I mean BIG) screwdriver under my carpet, etc. To get it off the floor pan. Then we welded the SFC brace to the floor.

I love mine, they fit like a glove when we installed them. Not a single fitment problem. And even my wife commented on how much the car ('82 Z28 w/T tops) had changed after they were installed. I am going to have another set of Spohn SFC's installed on my IROCZ before it goes to the body/paint shop.

I have Global West SFCs. They too are stitch welded every six inches or so. Highly recommended for any thirdgen car.

Don't do it the lazy way, do it the right way. After all, "if it's worth doing...".

If you are paying for SFCs, adding their extra weight to your car, and want their full benifits in return you might as well do it right and get your moneys worth. It will make the chassis stiffer to have more connection points.

I agree. I've got the SSM SFCs which are welded to the pinch rail(I think that's the term) where the rocker, floor board, etc. connect. A body man friend said this is one of the strongest joints in the car, hence its need to be welded to. As for the carpet, be careful. I didn't melt/light mine, but I probably got lucky.
