Update: I called them this morning and he said if we could get ten of us interested he would be in for developing the kit. I verified the price and he said it would be in the area of the other kits he sold. The most expensive is the Corvette for $215. The Mustang kit is $175. I think the difference is a full plate on the back of the rotor or a partial plate with two bolts. He can do either I think once he has the design.
Interest expressed by these so far:
Doug Hilliard
TCorzett
jbak
Eidolon (maybe, depending on a plan for the GXP)
HuskerG8
ULTRA Z
