These pads fit a few cars - A4, A5, S4, S5, Q7. Part number DP42277R. Purchased some rear pads from eBay, seller sent me fronts instead. Will let them go for £110 including the shipping cost, enough to cover a purchase of rear pads. Figured I'd let them go for a slight discount as they're also low in stock in most places. Either PayPal Friends and Family, or Goods and Services (but you cover the fee, found at https://www.clothnappytree.com/ppcalculator/).
