First ever trackday I attended. I managed to avoid using the MX-5 as earth moving equipment, although I did have a couple of brown trouser moments when I overcooked it at Paddock Hill Bend. But I didn't spin the car :).
It was a lot of fun, although it did show that the suspension has a few miles on it. Brakes (original 1.6 disks with uprated, non-EBC pads) were fine, didn't get any fade but then again, you don't want to scrub off too much speed in an MX-5 anyway.
Still not quite sure if I'll keep the MX-5 and buy yet another runabout or go for something like an e30 318is. Not too much power, decent handling etc blah blah. But if I'm keeping the MX-5, I guess I'd need to rebush the suspension with some polybushes, replace the dampers and springs and get some 15" wheels with better tyres...
It would be tempting to go for something a bit more powerful, but as the instructor I booked pointed out, something fairly slow but well balanced like an MX-5 is actually a better car. As he pointed out when an Evo FQ-400 flew past "the guy's actually not that brilliant a driver but the car makes up for a lot".
Anyway, I guess I better look into booking another trackday next month.
