I'll be very interested in the test results, but we may have opened a can of worms here. My car has a tall FIA bar, but no sticker. I've no real idea of it's provenance or even age. Then there's the fixings to consider. Has it been put together correctly? Who's qualified to say? The car's 30 years old. There are several types of roll over bars used. Do we test them all? We may find that only full cages are acceptable. After all, they are the only one's tested on track on a fairly regular basis. Then there's the Club's insurers who must have a view on this? What standards do they require? What is the basic rational for track days anyway? Does the car have to have an MOT, most race cars don't? There's no scrutineering done ( but they will do a noise check ! ) Could I knock up a car in my garage and take it on track, so long as it has a good exhaust system and it looks okay from a distance? The issue of head / bar height surly must be the individuals responsibility. It's a simple check and one that could save your life. There's also the issue of belts, clothing, helmets, TYRES ( how often do you see track day tyres worn through to the wire, yet 2 laps ago were probably doing 100 MPH plus ! ) I don't know the answers, only what's acceptable to me, my risk in my car. It's just the others on track I worry about, which is why I prefer L7C trackdays. Clive
