Apparently, the PS universal hardware kit is NOT available for our platform. I don't know why it gets listed in the vehicle specific parts availability for the Contour, Cougar, and Mystique. The full Big Brake kit is availble for over $1000.
On the vehicles that the Plus kit is available for, the kit requires use of the PowerShot rotors. Still approaching $400.
Either way, I still think the FSVT conversion is the better way to go.
