I couldn't do a pagid vs stoptech. It rained for the first 2 sessions and then dried out the second 2 sessions.
The surface at COTA was fantastic! There was a crazy amount of grip in the braking zones. There were times I thought I was coming in too hot but the car would slow down so quickly.
So this is put off until 26-27 Jan. I'm sure the Stoptechs work well...I'm not sure if they are as good as the Pagids. The pagids are pretty damned good!
