You dont need 150 miles on a tire. You can scrub that bitch in within 35 miles on the street.
Track tires are cast no different. Racers dont have a chance to ride 150 miles on a set of tires before they go at it. You'll be fine on those tires. Unless ofcourse they're Dunlops or Bridgestones, then it doesnt matter how many miles are on them, they still wouldnt stick.

Does it affect you that much that some random guy 1500 miles away went and paid his own money for a 1000?
Do we really have to fight over who uses the back brake or not?
Do you have to argue over stupid pointless shit on the Internet?
