Hey everyone: This is Duane (builder and ex-owner of the 3/98 EC Turbo 4000). I'm here to clear the air as to what rotors were used in that G60 set-up. I'm fairly certain the rotors were for a '90 90Q, and NOT for the Coupe. Apparently, there is a difference between the two. They were purchased from KVR. Lemme know if I can clear up any more questions! Duane
