It would be interesting to see how a new set of shaved RA1's do with a very consistent driver. I wonder if the current RA1 compound is the same as the old tire. When doing some tire research I remember being told the RR was developed to replace the shaved RA1 due to the problem of the shoulders cording on shaved RA1's. They increased the rubber thickness on the shoulder.

How do the historic lap times compare with today? I sometimes feel like I am chasing a moving target, most of the group seems to get faster every season. Just when I think I am getting close, the goalposts move. I like it!
