I was just quoted $2800 for upper&lower front control arms on a C7 A6 -having done it on my C6, it seems a little steep but probably audi parts which I didn't use last time
If you look at the surface of the rotor you'll notice it's not smooth, it's quite scored and not a flat surface. If you install new pads on these wavy rotors you will have a flat surface pad riding on a wavy surface rotor. Eventually the pad and rotor will wear each other to a new pattern...but not flat. Now lets say the rotors warp and you have to replace them anyway but you want to re-use the pads ...... you'll have a wavy pad riding on a flat rotor.... they will wear each other again eventually but not flat. So my point is if you put new pads and new rotors both surfaces will be flat and they are likely to wear each other flat. This gives you a higher chance of being able to reuse that rotor when the pads are done because it will likely stay flat. Does that make sense?

That's a little steep, I charge $2k for upper, lower and ball joints....parts and labor.
why would I have to replace pads if the rotors warp? you said, "you'll have to replace the whole thing" - just curious
