Hi guys, I have a 4 point half cage in my mazda mx5 originally it cost me 550 from brown davis who manufactured it in sydney/melborne where ever it was Such is the demand it was an off the shelf item that can be installed in less than an hour I also have sparco jnr seats and looking at harnesses in the near future original reason for getting the roll cage was for doing weekend track work out at QR for saturday arvo sprints etc When i did it the insurance company etc or DOT etc didn'thave a problem with it as the car is a convertible chassis from the factory and the part is regarded as a saftey feature now though with alot more money invested in the car it rarely sees the track and just draws attention from the boys in blue My cage was fitted with harness mounting points etc so they are easy to engineer so on so forth when i do it! What phases me is when you see a commodore or falcon with a 6 point roll cage ie bars going down to the back parcel shelf and side intrusion that people will still get in the back of these cars The main problem with roll cages on the street is from a after accident point of view commonly cut to remove the turret are the a'b and c pillars to gain access to victims in such a case, when these are is substanially stregnthened it is no longer as easily accesable as originally was intended from the manufacturer Then there is the fitting of harnesses in road cars! most people have them running either strait dowm to the floor or to the gap between the bottom and top part of the rear seat! which are both dangerous and illegal the minimum lower angle is 30deg below horizontal any more than the 30 deg and you risk breaking your back in a roll over as the seat cannot compress where as if you did have the right angle your seat can actually compress backwards into the rear of the car area . in the case of my mazda the harness points are directly horizontal to the point where they go through the chair there are also other things to consider a lap sash seat belt offers the occupant to be able to 'duck' ie move in board important in a convertable but also in a sedan coupe etc if you fit harnesses to a car without a cage you run the risk of not being able to be pushed down effectively having your haed pushed into the roof so it becomes as some one said before a wepon rather than a saftey device if not used with the other right parts equipment etc Just to add it also as said increases strucutural stregnth in a side impact if my car was T boned at 60 km's an hour by a landcruiser or small 4wd for that matter it is usually most certain death as your head is right in the bumper bar line with the roll cage the bumper bar hits it first and not your head you dont realise how dangerous the road is till you get into a small car and look up at the world! especially when we are only allowed to lower our cars a tiny bit but 4wdrivers can go up a great deal (but thats a totally different debate!) I for one am happy with my roll cage and will take it with me to my next mx5 [Report message to a moderator]
