X-brace door bars

Hey everyone,

I may be posting this a little late, but I am wondering about the rule regarding the X-Brace door bar design. NASA tech approves the 'x' design without gussets and as far as I am aware, if it will pass NASA tech, then it should pass ChampCar tech, correct? I can get the gussets put in, but if the answer is a definitive "it will pass", then I'd rather spend my time doing other things.

 

Here is a picture of the door bar as it stands, right now (the driver's side is identical):

@mhr650 You are certain it will pass? I hate to get down there, for my first race, and find out the gussets are required. Are there other cars that have the x-brace without gussets? Is there a person that runs Tech that can chime in (if that's not you), or that I can contact directly, to ease my worry about this? :)

Try: Phil.McKinney@champcar.org  Phil is head of tech.  Expect a bit of a wait to hear back, but Phil is the man to ask.  You can also CC tech@champcar.org as well, and see if you get a quicker response. 

 

The biggest part that I see being an issue is that you state the drivers side is the same, if so, that picture says it won't pass.  The rules require 2 single piece bars, so a bar above or below the X that is unbroken connecting the main hoop vertical to the front hoop vertical will need to be added.

NO it will not pass tech as shown in the picture.  It doesn't meet the rule shown below.

 

3.2.3. Two continuous/unbroken driver-side door bars (labeled “7”) that will prevent cockpit intrusion. NASCAR-style or X-design (with gussets) is acceptable

 

But if you have a lower still bar and this X configuration it will pass. 

I would recommend adding gussets to all of these configurations.
