Adding lightness
 
I didn't see this info anywhere here when I searched so here it is. If you ever wondered how much those stock door beams weigh on your second gen, 12.5lbs ea. If you don't have a full cage with NASCAR style door bars look elsewhere for weight loss, those 12.5lbs will save your bacon.

Each beam earns you almost 7 ft of 13/4" .095 DOM :bigthumb:

Stock door beams should only be removed as explained above(nascar door bars), or in an AX car.

ya, never remove those door beams unless you got at least 2 or 3 horizontal bars and a few vertical bars supporting the horizontal bars. We made the mistake of removing the door beams on a 2nd gen and ive never seen a door cave in so easilly.
