If you went through a set of tyres at Keevil then something is wrong. sh!t tyres, wrong pressures, wrong alignment. Same with your brakes, must be real cheap ones. Keevil is the roughest of the surfaces of their airfield circuits. Hulls intron is a good better surface and they have a free handling course as well if you like handbrake turns etc.
I like the airfield days because of the surface changes, makes a nice change from smooth Tarmac.
Motorsport events run a well organised day, the briefing takes too long and the open pit lane time starts too late in the morning for my liking. They can be a bit over cautious with their checking of wrist band etc but I would rather have them more safety conscious than not be bothered about my safety. We have done about 40 or 50 of their airfield days and never seen a serious accident yet, and never seen two cars crash into each other.
I wish I could afford to do a circuit track day every time but money dictates we have to do airfield days as well to keep the cost down.
Enjoy your track toy, buy secondhand wheels with tyres on to keep your costs down, get your alignment done and some oem brakes which should last longer than what you have on now.

I enjoy both circuit days and airfield days
