The D212GP pros are not easy to find in the US. The only sell them on the other side of the pond or at a Dunlop race tire dealer.
I can easily say that this are the best high performance tires I have ever used. The braking stability and high speed stability is amazing and all of the grip that one can reasonably use with very good predictability/feel.
GPA pros and D212GP pros are very different tires.
