I know this topic has come up before, but I'm getting questioned over the integrity of the GT's rollover structure. Last year I ran the Big Bend Open Road Race in the 125 average / 140 max category. This year I want to move up to the 140/168 class, and the tech guy has asked for proof that the GT has built-in rollover protection. I know the Silver State has accepted this, and I found a thread where someone was trying to get NHRA to accept the car as-is, but I've not found anything definitive.
Is there any documentation (SAE paper etc) that speaks to the car's rollover protection? Anyone have proof of acceptance in other races of this speed level?
The irony is that every year there's a bunch of Vettes running in this speed class with no rollbar, and I'm guessing that our GTs are waaay stronger than them, but when the Tech guys ask, you gotta answer
 
 
That was an interesting list. Couldn't agree more on the 4 door Porches looks......
 
Nice find Gary
 
Nice find! I pasted the link and sent it to the tech guy, let's see what he thinks.
 
Texas Mile accepted our cars as is. Threads about this somewhere....
 
why not just say you are not planning on rolling over??
 
I was told there was zoro damage in the crush test and it was used in a production car. My source would not give the number???
 
I'd be more worried about getting out with the top of the door pinned against the ground. I suppose your windows will be down at an event though.

New GT. How do you get out if you find yourself shiny side down? Is the gorilla glass on the sides? Would be difficult to break.
 
I believe I read that it will be used on the front, rear and the glass between the passenger compartment and the engine bay... not the side windows.

No Gorilla Glass on the sides, most likely for this very reason.
 
WooHoo! Tech just approved me for 140/168!

Jalopnik obviously is the over-riding automotive technical authority

Now I have to gently break the news to my navigator, he was twitchy last year at 125/140
 
Legit approval. Tell your nav 170 feels like highway speed. Truth.

Of course, slowing rapidly from 170 could be life altering.
 
Great News. Times I've done the Texas Mile was told at the tech inspection by the head inspector that the Ford GT is the only production car they will allow to run in the +199 mph category without a roll cage installed. Car is built Ford Tough. Oh wait that is my F150!
