Looking for a streetable track car cage setup for my FB. I believe this one is a bolt in and that's what id prefer, id like to run an interior. Is this any good? 1979-1985 Mazda RX7 8 Point Roll Bar EWS ⋆ S&W Race Cars

Street car and cage do not really go together, I would look at a bolt in harness bar if you are looking to run harnesses.

Autopower and Kirk also had bolt in roll bars and roll cages for that chassis. Not sure if they still do...
The S&W looks ok.

I would never recommend a harness bar for any purpose. Using a four point harness without the protection of a roll bar is not smart. That said, I also don't like to see cages in street cars unless you intend to drive around with a helmet on. The compromise would be a roll bar that is mounted far enough back that the driver and passengers heads can't hit it.

The problem with the S&W roll bar is that it is not made out of seamless tubing. Seamless DOM tubing is required by the SCCA, NASA and likely most other road race/time trials sanctioning bodies. It is also made out of material that is way to heavy. Look at Kirk Welding or Autopower. Better yet, find a cage builder in your area and have one welded in that meets the rules of the groups you will be racing with.
