I'll certainly look to get a set... am i correct in thinking the part number is DP31513C and i just need to buy 1 set(fronts) which has 8 pads?An Audi service department 'might' fit them - however would you really want to pay the £100+ an hour labour rate? Going to an independent is a much better path and the one I would recommend for the pad replacement.
You do 'need' them - as fitting Redstuffs now will save you at least £500 for a pair of front discs plus fitting. The service life of the OEM pads is such that the discs will likely be worn past the safe limit before the pads themselves need replacing.
My RSQ3 has 16k on the clock now and I'll replace the front pads (arriving today) as soon as my crazy travel schedule permits.
I've got access to Volksmaster branches in and around Manchester area, might see what they will charge to fit a set... I'm not sure i can trust my RS wheels with some of the other garages i know haha
