NASCAR style door bars

Is that necessary?  the entire side of our car will lift now with the cage. 

Depends on if you want to crush in your rocker panel under the car?

 

This is just a little stub that carries the weight of the car and it's very easy to place the jack properly without bending over.

5F7ED4A8-BC6F-4D82-9F51-4E2ACBEEF6B4.jpegEdit note: this one took some thought and planning to weld the door bars up. To get to the welds on the outside of the sill bar, everything was fitted and tacked together, then I removed the 2 lower bars to weld them up fully, then reinstall. Snaking them through the B-pillar, 1 on each side was tricky. But it was cool once finished! (And more importantly, strong and safe. ) 

 

 


OMG, can you build my next cage please? :)

We use the factory jack points... If you use the front the entire side lifts up. Not a ton of weight outback anymore.

Please don't.

 

9.4. NERF BARS OR EXO-SKELETON

9.4.1. Added structural elements that extend beyond the outline of the original body line are not allowed.

If it is done right with rules / common sense in mind, you end up with an easy way to jack entire side of the car while leaving really good spots to put the jack stands (aka, the a-pillar and main hoop touch down points / or stock jacking points)

 

Can you see it?   Curved bar that goes down from the middle of the sill bar, inside the rocker.  It protrudes locally under the body about the thickness of the plate that is welded to the bottom of the tube, also about the same height off the ground as the non-flattened pinch weld and sits higher than the floor pan.  It is not structure, nor exo-skeleton and does not extend past body line when viewed from above, or lower than the lowest plane of the body.  Similar treatment to passenger side.

Are we allowed to tie into the footwell for free like this with two bars or are these the one allowed past the firewall and the allowed footwell bar? Or are these two in addition to the one allowed past the firewall per side?

So in a car with the footwells so far ahead of the door pillar, is it better to have the A pillar bar go straight down at the door or keep the pillar angle and land at the footwell with a vertical down from the dash height to land the door bars on?

It’s difficult to see in this drawing from the BCCR, but the two lower bars circled are the 2 foot well intrusion bars allowed. (They run fore/aft, the drawing makes them look lateral..) 

The upper bar to the strut tower is also circled. That one can go through the firewall.

I just one bar on each side.  It is continuous from the a pillar to the strut tower.  However, I played it to the inside and outside of the firewall too.

 

Less bars is less weight, but maybe a bit less protection.

That's not going to work with a road race car because most of them you can't get the jack in under the front center. This setup requires that you jack from the front  center unlike most road race cars which jack from the side.

An adapter to use a floor jack on the side works but not for every car for sure.
