Hey Kim, did you forget to add points for tire width, or are you running 205's and 230's?

So, recalculation time:
GGR = 325 base points + 90 points for wheel size (7.5 f, 9 r) = 415 pts = AX 12
Zone 8 = 320 base points + 70 points for tire (225-205 = 20, 255-205 = 50) = 390 pts = CC13
Thanks for keeping me honest! CC13, not CC14.

Hmmm... A couple of interesting things here. I am running 225s on the front, but have 255s on the rear (stock 17" wheels/tires). I was also using the online GGR calculator, which calculates differently than the Zone 8 rules, AND I forgot that the "standard" 986 Boxster used a 16" wheel (did they ever actually sell one with a 16" wheel - I have never seen on with less than the 17" wheel).
So, recalculation time:
GGR = 325 base points + 90 points for wheel size (7.5 f, 9 r) = 415 pts = AX 12
Zone 8 = 320 base points + 70 points for tire (225-205 = 20, 255-205 = 50) = 390 pts = CC13
Thanks for keeping me honest! CC13, not CC14.
