Oops, just checked mine because they were looking a little thin. Measurement came in at 22.4mm, ouch. Still seemed to work fine though on Sunday. Luckily I have a couple of sets of KHZ 7075 shoes, best I whip those in before the next Nats next weekend.

Also, after the race day on Sunday, there is spilt fuel covered in dust all over the inside of the car and the engine. I guess this is either my pit guy being too liberal with the refuelling or the tank opening when I bin it or both. What do you guys think?
