NASA allows Camaro 2010+ but not Mustang

[kutsyy]

NASA seems to change list of convertibles that will pass tech “as is” for racing and it included Camaro 2010+ but not Mustang. Does anyone know what roll protection Camaro has that Mustang doesn't?

The beltline? It's so high it doesn't need roll protection.

Sorry, couldn't resist. I have no idea.

The rules state with top closed only. I found another Camaro race reference to the A-pillar plus closed roof being legal. Their tops are also rated to open and close at speed. I can only surmise that the top is significantly more robust than ours? That perhaps a closed roof adds enough structural rigidity to make it safe enough (driver risk)?

Also noted, the Mustang Vert is not specifically excluded in that list like some cars.

I was also surprised about "top closed only", but it sounds wrong that top is structural, may be it is just enough. As for opening while driving (up to 30mph), I thought it is because the back opens up so air can go through.

I think that someone had ZL1 vent and went thought the trouble to get NASA to inspect it, but since there is no GT350 vet, nobody bothered. Just wanted to see if I missed anything about the differences....

"Additional safety structural reinforcements are designed to improve noise and vibration characteristics, while also contributing to the elimination of cowl/steering wheel shake. They include a hydrofromed tube in the A-pillars, an inner reinforcement bracket in the windshield header, a reinforced front hinge pillar and reinforcements inside the rockers."


I wonder if the A-pillar is actually reinforced enough to provide roll over protection? thus no need for roll bar

interesting, but seems that mustang have the same: https://www.repairerdrivennews.com/...-steel-on-f-150-mustang-structural-adhesives/ "the A-pillar is its shift to a hydroformed tube, beginning with the 2015 Mustang convertible"
