David; I recommend a good crash helmet.Advance your timing to 14 degrees,
make sure you run 185-60-14 tyres on original rims at 33psi hot, fill up
with gull or challenge 96 octane and prepare to have some sideways fun.Ross

For club driver training days it's usually up to the organiser, but
generally sessions involving speed and a track require a helmet only for
fast bits.

For car club MANZ sanctioned speed events in an open sports car, a certified
roll bar is required along with complying helmet, overalls, harness, seat
with holes for the harness, fire extinguisher, and compliance with all
relevant items in the safety section of the MANZ manual No. 30. Quite
complex really and quite a bit of work and expense to get a car up to
scratch. The spending doesn't stop, because some things have a use by date.
I found it quite discouraging for a small time competitor just in it for
fun, but I guess it's good to be safe.

My understanding of the regs is that a compliant roll bar doesn't need a
harness because all the bars are behind the driver and you don't need a road
authority card. MX5's seem to get away with non complying style (roll) bars,
even though some may do more harm to you in a roll over.
A full cage is different in that you do need harnesses to keep you in your
seat so as not to scone your nut on the bars in a crash. Because you need
harnesses, you need a road authority card, a clubsport licence minimum and a
vehicle log book. You need to do at least three MANZ events a year to keep
your authority card. This stops non genuine competitors from having a cage.
This is as I remember reading it, but I could be wrong on a point or two.

I decided to go full cage as the best safety option for serious racing,
despite the seemingly large task of complying. It all costs money, but I
want to walk away from the big one.
