We got the GSXR front end set up and I got about 6 laps on it before it started to drizzle. So I came in and swapped to the Superstock '05 with DOT tires and went back out again.
After a while the rain really started to come down and my rear end started moving around too much, so I came in.
I found the rear tire pressure too low, which was probably the problem. But it is pouring now, so I'm gonna nap for a bit and go out later...
