Sold my 01 A4 recently before I had a chance to install new rear pads & rotors. These are brand-new Zimmerman rear rotors (245x10mm - p/n N1000-232196) that'll fit any 1996-2001 A4 Quattro. Also selling brand-new Mintex red-box pads. Asking $90 for the rotors and $38 for the pads (shipped prices). Brake pads fit the following cars:

A4 1.8 from Ch#8D-V-168351 ('97)
thru Ch#8E-4-180000 ('04)
w/245 mm Disc
