Does anyone know the universal D number for the 4-pot brake pads? All brake linings have a D-somethng part number, to make it easier to cross reference from one brand to the next. For example I think the 2-pot pads are d-721. If you have that number, it's much easier to find pads at your local parts store where they don't list an Impreza with 4-pots. I think that 300zxTT pads, or 89-95 toyota 4x4 pads may be the same.
