I couldn't stand that sound either, so I called up a buddy who owns a body shop to see if he had any totaled P-cars to cut the buckle out of the seatbelts. Well he didn't have any P-cars, but did have a totalled Hyundai. Yes, ironically enough Hyundai copied the seatbelt pattern from Porsche for their cars. So whenever I use my harnesses for track use, I slip the Hyundai seatbelt buckle into the 3 pt. hole. Works like a charm.
