the "retro" fit to the older style brakes, if done at the dealer under
warranty was actually an "after" fit, using the front struts & brakes also
installed on the '92 S4.

brake discs should be 276mm x 25mm ventilated (441-615-301A)
caliper is a Girling G60 2-piston floating (no pistons on outboard side)
(l) 447-615-123  (r) 447-615-124  (btw, for those into specs, the two
pistons measure 40 and 45 mm)
