I remember seeing someone get this kit. It was a yellow car and he had done a lot of work to the car. If I remember right, he didn't like the kit. I think he called it cheap and ended up going with stock GTS rotors.

Also, the TRD Toyota Celica with the Supercharger featured in the first issue of C&D: BOOST was a GT with a GTS rear disc conversion. They listed the price as $300. That's the path I'd go. See if you can find someone with parts that can get you the bits. Maybe Dave Draper?
