Removable Door Bars

Does anyone have experience with making a cage for a track car with removable door bars? I'm building a cage for my track car, using 1.5" x .095 DOM. This is for track days not racing, so I don't have to worry about rules, but I'm using SCCA racing as a guide for tubing and mounting points. I'd like to make the door bars removable, and am deciding between sleeving the connections with a larger piece of tube, or using weld in clamps like this: http://www.tmrcustoms.com/store/inde...oducts_id=2080 Any experience with these types of clamps?

I think those would be fine. Actually, they should improve stiffness over a typical NHRA legal door bar, like this:

Because the two halves are keyed together and held with two bolts.

The only concern I would have is the sharp square corners that will be exposed when you have the door bar out. Depending on the placement, they could literally be a real pain.

So would it be bolt in or pin in? I have seen some where the lower front is a pivot/hinge and the top rear has a spring pin so you can open the car door, then unpin and swing out the door bar for entry/exit. Are you going to just hop over it when it's installed and take it out for when you're hooning around town?

I envision using two sets of clamps, one towards each end of the bar, so that the majority of the bar can be removed for proper hooning, but I would leave it installed and padded for track sessions.

You can get on track by attending lapping days with many organizations from car clubs to track day specialists, or you can race with any of the organizations such as SCCA, NASA or marque-specific racing like BMW Club or Porsche Club. The lapping days don't require a cage, but I've done it often enough in an old enough car that I decided that I felt safer going with at least a roll bar and a proper harness, and what the heck, why not stiffen the frame up with the cage "while you are in there"?
