Fast wheels are sold by www.wheelandtirezone.com in Canada. I was told to contact a rep at 727-522-5741 regarding U.S. shops. I'll post more once I've had a chance to call the rep.

I'm told Wheel and Tire Zone also sells the ZEONs but the guy at the other end of the email wasn't very helpful with specifics on the wheel, just kept saying how much it would cost and yep, they're available

I believe the ZEONs are part of Cooper Tire's racing program. I'm waiting for Tuner Transformation to repeat the Saturn ION episode on June 29th to capture a photo of the wheels.
