US, I really dont know why the TCS opened it to any 17.5. Pick one manufacturer who wants to sell major volume at a considerable discount to the racers, and you have eliminated alot of issues. Even if that means TCS has a full documented agreement with a manufacturer to guarantee a price and stock levels.
