No Uk site that I know of, its a shame I think it would be pretty popular.
JR, its alright saying that they last for 1000 or so after 70 miles but what happens when the people at the front start buying new tyres to be faster? everyone else does the same to catch up and the cost goes up. This always happens the more popular a championship gets.
