I'm only going to weigh in on one thing here, and that's the HANS device. I realise that it's an added expense. I understand that doing the mods to your cars can be a PITA.
I posted this link in a different thread three years ago, and I strongly encourage you to read it - it's about how a HANS device works, how it saves lives, and the dangers of not fitting and using one when competing in motor sports:

Why have I weighed in? Two reasons, the second one purely selfish.
> When I lived in the States, a man down the street from me who I didn't know apart from the neighbourly friendly nod and wave, was killed in a racing incident that caused almost no damage to his car, but the rapid deceleration caused a basilar skull fracture that claimed his life. The dynamics were not understood back then, and it was put down as a tragic unforeseeable death - as were many accidents those days. I sometimes wonder what he would have went on to do and accomplish in his life if he had a HANS device.
> As club chairman, one of the things I have dreaded on a regular basis is getting news that a Speed Series competitor or a club member has been seriously injured or killed while driving their Westfield, and then carrying and expressing the club members' sympathies to their relatives. My blood has run cold a few times already when I get a phone call detailing some pretty spectacular crashes that have happened (two rollovers and a venture into the woods which you all know about immediately spring to mind). Gents, I have seen more than enough funerals in my time and have no desire to go to any more if it can be avoided through spending a bit of money. Yeah, that's pretty selfish of me I know, but I don't care nor do I hide from it.
So yes, I'm sympathetic to the added cost and installation hassle of a HANS device - up to a point. Sometimes we have to think about how our actions (or inaction) would affect those we love. Please - if you compete in motor sports, fit a HANS device.
