when Autopower opens up tomorrow ill get this info for you guys. Ill see if they have some installed pictures of these in all the rotary cars they offer them for.
the following is quoted from Autopowerindustries.com
"Our roll bars and cages meet or exceed the safety requirements for most competition sanctioning organizations. Our bars and cages have been designed to easily install and provide maximum protection. The fit in your vehicle allows quick and easy entry and most importantly, quick exiting, while conforming closely to your interior for a clean, unobtrusive look and feel. All of our bars and cages are certified MIG welded and precision jig notched, providing you with the maximum strength and best fit available. Every roll bar or cage has been designed to fit *specific car models so only minor *modifications are necessary for the instal*lation. Most applications are a true bolt-in and require NO WELDING."
I have personally seen these in an S2000 and it looks great, its real subtle and they come in black. So they do stay hidden until you get the full roll caged that come up into the passenger area instead of behind the seats. but i do know they try to stay away from getting in the way of anything at all, autopower has been around for a while here is a link to their entire application catalog.
