Here is a street driver RR with a full roll bar setup with down tubes front and back. It came out super nice but it isn't that easy to crawl in and out of the car. But it is a 10 second street car so it needs the full cage setup to be legal. It does take a lot of work to fit the cage tight to the head liner and inner panels. The front header bar on this car got put too low which was a pain but nothing can be done about it now.
