Only have only run on Bridgestones. They are so damn consistent and while not always top grip, far more predictable and lasting. I'd drive to events on them, run the event and drive home while others were still in the paddock
140 treadwear also kept you out of 'race' categories in time attack.
I have run the 01Rs (for years) 11Rs and am now on 71Rs and absolutely love em.
They are also more affordable than 'top brands' such as Mich et al.
I run 16" rims and often get full sets of 225/45 or 50/16s for $600-750.
