Interpreting MSA rule book re roll cages
Discussion
Anyone out there use this book? I am trying to understand the rules re roll cage tube sizes.
Car is a 1967 Lotus Elan. I plan to use it in Street Class drag racing, sprints and hill climbs. It will be a hardtop. The regs seem to indicate that I can get away with just a hoop of 45mm diameter - 1.6.1 (c)
My question is - I want to fit a full roll cage as we need to stiffen up the chassis as it is as stiff as a strip of liquorice, even when modified to 26R standard. So, does the additional tubing have to also be 45mm diameter or can I use 38mm as I would class these tubes as optional? I plan to use T45.
