Rollcage for street car

[anjin]

Go to the CAMS technical specification - that will tell you exactly what is legal in Cams controlled racing. Bolt in is ok - but there are rules on size and thickness of plates on the cage and the body, bolts etc. The requirements are very clear, with diagrams etc of many configurations.
What is required in Cams won't be legal on the road - the bars in the front of the car are considered dangerous to head and limbs. Quite right too - remember you have to wear a helmet on the track for protection from the cage, among the other dangers.

Any thing more than a half cage on the street is illegal and won't be engineered. Any half cage with in 250mm of a person will need to be padded with padded as per adr regulations.
All mounting specifications are out lined in the adr also.

If a 4 seater rear seats must be removed and all mounting points pluged.

Ive heard that most cars that run a bolt in or Japanese made cage aint allowed to compete in most CAMS or ANDRA affiliated races due to there lack of structural design and more importantly being not welded in, any truth to this? Was considering a bolt in cage in the future for track work so i can run a harness for my bucket seat

One thing to note with the idea of using a harness for extra safety. You are exposing yourself to a whole new hazard. The OEM seat belt and airbag works great. When switching to the use of a harness it is strongly recommended that you use a HANS device. This is because there is no give in the harness like there is with a seat belt/ airbag setup. That in turn means with the weight of your head and helmet move forward while your body stays still. Your neck is now the weak point. Earlier this year there was a death as a result. This is a extra cost that most people dont take into account.

dnapol is correct. Unless your going door to door, which 95% of us don't. Bolt in cages are fine. BUT, the rules have changed in a few states as to cage design and dimensions. Sadly for some versions of the japanese cages (safety 21/cusco/carbing), It means you cannot legally run them on a road car.
