what i'm suggesting is that having merely harnesses and a HANS device without a roll cage is not as effective, and potentially more harmful, especially for Z06 drivers.
here's why....hopefully
the comment about civic and low power cars is to suggest that lower power cars are simply less likely to encounter the consequences than say a Z06.....the logic behind this is that they (civis and the likes) are simply slow........still doesn't make sense? ok...why do most drag strips, NHRA, etc. require cars going faster than 11.99 to have, at the least, a roll bar...and a full cage for 9.99 or better? obviously...they believe that a car that's capable of going faster carries more risk...and we're talking a straight line. what's the trap speed for 11.99...120? 9.99...145? 145 mph in a straight line from a dead stop...a quarter mile long....i would bet the Z06 can hit 145 mph on some of the bigger tracks in the US...laguna seca, button willows, thunder hill, road america, road atlanta, sebring, VIR. this isn't to say that every Z06 owner will go no nucking futs and push their cars 10/10ths.
certainly if you drove slow and conservatively, stock restraints should suffice, i mean, this is still a street vehicle that you'd have to drive home, right? if you feel the need to step up to harnesses and a HANS device and still drive conservatively as you would with stock restraints...sure, the likelihood of a rollover are still minimal and the restraint offered by the harnesses and HANS device will be that much better. but putting in harnesses and adding a HANS device so you can step it up to the next level.....i personally believe that that is not the right mentality, you're bargaining with yourself and making compromises you shouldn't make, ie...your well being backed by harnesses/HANS device vs time/money/convenience of putting in a proper roll cage.
btw...that's pretty amazing that T1 (wheel-to-wheel racing, no?) doesn't require fuel cells.
