Zap, you make very good points. Cage is great IF you are wearing a helmet which at the track you are, on the street its going to get brains on it if you crash. I don`t know how much testing a bit of vinyl covered foam that goes over the bars has been subjected to. A purpose built cage is attached to atleast subframe rail connectors or better, its apart of the entire chassis structure. A bolt in partial cage? Hmmmmm. It might just meet minimum requirements and little else. I fully agree its uncharted waters, car manufacturers won`t generally throw a family car at along a concrete wall at 120 mph to simulate whats going to happen at a dragstrip, they`d maintain they build road cars. Basically I`m saying this ALL needs looking at with an even handed approach. We all see stuff at the drag strip that leaves us wondering. Cars are going quicker. Lots of people are attemping to break unofficial records that obviously they are going to be told they can no longer use the car on the track in its current state. that's pretty hard to legislate against or is it? I wonder that sooner or later they might just attempt that to cover their arse. The 4 point harness is the start.
