Ran them on astroturf and carpet so far and they rock, the low sidewall helps give a nice stable turn-in like the Schumacher SST tyres we run in the BRCA series. Wear rate is good too, what you see is my last set though
and they are illegal for the BRCA series at the mo because they are not commercially available in this country.
Getting pro-line back on the scene can only help the scale as far as I can see!
