No problem. I got mine from Replacement Brake Parts and Performance Brake Upgrades. I used coupon code FP08010 to save $10 on the order. Shipping was free for me in the US, but obviously not to the UK.

I found out after I bought them that Import Performance Auto Parts - Cold Air Intakes, Brake Pads, Brake Rotors, Exhausts and Suspension would have been slightly cheaper, but overall I'm very satisfied.
