I am pointing to the metal with the holes next to the windshield. I was wondering what this was and it's purpose. I have noticed these on race cars and such. Is this just the interior stripped out? Or is this some kind of cage? sorry for the gay thread and noobity.

 

I believe it's part of the cage. Both the A and B pillars have it. It has holes to make the support structure light and rigid. This technology is applied to aircrafts, boats, and just about everything.

 

those are handle bars to hang on to when your car is turning.

 

i need to get me some of those.
