If you search around the forums (like corvette) I noticed there are folk running the V700s so I am guessing its like Australia, you need to special order them. They aren't like a normal tyre order as you need to specify soft/medium or hard compounds.
Just an update on the rain and wet road performance of the v70a . They are really good. Even brisk accelleration from a start was ok, on the draggy i was getting mid to high 4 second 0-100kmh in the rain. Not what I'd expect from a track tyre. They are wearing pretty quick though all the same
