Legal issues?? I already have mine engineer approved with a 6 point cage. The new cage I got from Bond roll bars in sydney its cams and FIA aproved .The materials where not that $$$ Just over $700 the biggest job is getting it all to fit nice an neat and in the right position. Its much the same as my old cage
6 point expect it has side intrusion door bars a bar at rear tying in teh rear wheel arches and a set belt bar for teh harnesses to connect to They also gave me another nength to do any extra stuff I migth want to do I migth triangulate the main hoop to strengthen it a bit.
cheers Andrew
