I've run on two sets of R1's.
As compared to Hoosier R6's...
Pro's:
Cheaper, more heat cycles than R6's, almost as much grip,
Con's:
Heavier than R6's, less heat cycles, my last set tended to cord and chunk towards the end of their life cycle, R6's have way more early life grip.
Unless you are racing, these are a good overall track tire.
