Tubular or Boxed SFC's?
Which would you consider to be better or stronger? Any help would be great, thanks. Oh yeah, i am talking about weld-ins of course! thanks

tubular isnt supposed to collapse as much as boxed stuff goes but i dont really think it would matter all that much unless you are putting out gobs of power that will really twist the car.

Tubular is around 14 lbs lighter than boxed type.
Tubular is slightly stronger due to no sharp bends like the boxed type.
PS I'm running box'd Spohn SFCs and other suspension stuff. I like them... bottom line Spohn makes his stuff to last.

Anyway, let's not turn this into an engineering debate. The bottom line is either type/size tubing is overkill for the application. It doesn't matter if you weld in a 1.5x2.5 SFC, or a 1.75 tubular SFC, either one is gonna lock the chassis together and do the job we want it to do. We're not building Abram's tanks! The actual goal is to have a piece that will adequately tie the frame together, and not weigh any more then necessary. -Steve Spohn
