Yokohama AD09 (1st Track Day)

First time with AD09s on a VERY GREEN Thunderhill. Lots of spins and off-tracking during the day, with track temps in the 30s and it taking a long time for tires to get up to speed. 

Overall, impressed with the tires. They don't require as much babying as the old Contis in terms of warm up time and tire pressures. They took maybe a lap or two to get up to speed, but gripped well and didn't mind a bit of multi-tasking. Excited to see what they can do with better track conditions.
