I got to talking to Marshall and Michael yesterday about door bars. They said that NASCAR-type door bars are now required.
If that's true, then Hallett is most likely a wash. I only have a single door bar in my cage, and chances are damned slim that I'll be able to get NASCAR bars installed before Hallet.
So, I checked out both the CCR's and the AI rules. Here;s what I could find:
From the AI rules:
5.12 Roll Cage
The roll cage must comply with the roll cage standards of the NASA CCR. However, a roll cage may also provide additional chassis stiffening through the use of alternative mounting points. As such, the roll cage mounting points are unrestricted. The roll cage may also pass through the firewall and attach to the front shock towers. Additional bracing may also be welded to the front of the shock tower and extend forward and down to the forward most part of the original frame rail. This bracing may not pass through the shock tower and must not form the upper mounting point for an aftermarket SLA system as the SLA must still remain within the original shock tower. The mounting plate material must conform to the specification in the NASA CCR but the plate size and design is unrestricted. Interior body panels and sheetmetal may be bent or altered to accommodate the roll bar design.
5.13 Door Safety Bars
All vehicles must meet the door safety bar requirements found in the NASA CCR
OK, so the AI rules defer to the CCRs concerning door bars.
From the CR:
15.6.12 Door Bars / Side Impact Protection
At least one (1) door bar on driver side and one (1) on the passenger side must be used.
At least two (2) door bars on the driver side and one (1) door bar on the passenger side
must be installed in all vehicles that obtain a new logbook after January 1st, 2007.
All vehicles, regardless of date of manufacture or date of logbook issuance will be
required to have at least two (2) door bars on the driver side and one (1) door bar on the
passenger side starting January 1st, 2011.
Unless superseded by class rules, modifications to any non-chassis structure (such as
door panels, inner door sheet metal, windows, door internals, etc.) may be made to
accommodate any allowed door bar configuration. However, removal of material and /
or modifications is limited to 1) the least amount to accommodate the door bar(s), and 2)
can serve no other function. Holes in the door jam (B-pillar) may be permitted to
accommodate door bars; however the structure should not be “notched” so as to weaken
it.
So, if I'm reading this right, my car should be legal with a single door bar until January, 2011 as long as I don't have to get a new logbopok, correct?
What would cause me to have to get a new logbook? That is the key question, I think.
(And for those of you who are thinking, "Don't be a cheapass, get the NASCAR bars!" I'm getting them as soon as possible, but I really don't think that'll happen before Hallett.)
