Had originally ordered this set up from another company back in April. They kept putting me off saying they were waiting for rotors. In June I was able to cancel. Ordered again from a different company only to have order cancelled a week later saying it was out of stock. Ordered from speedway received it 4 days later. Lesson learned, Speedway first.
