Yep, I drive it to the track. I carry spares for the stuff I'm most likely to break, rotors, pads endlinks etc. And carry a decent supply of stuff (tape, chewing gum and fishing line) should I have to kludg something together to get home, like my IC hose last year.
I tend to break stuff about every 3rd or 4th weekend out. This weekend it kind of piled up on me, but getting home wasn't an issue, just stopping when I got there !! More fried brakes, which I planned for, as I was on old rotors and street pads. My new race pads didn't arrive on time. I'll get into details when I do my write-up.
When I grow up, I hope to have a credit card with a high enough limit to pay for a tow, should I ever actually need one !Laugh!
