Do you think this kind of work is 'year/model' specific? I kinda don't think so....

Should be parts cost, plus an hours per axle...IMO. Do the math. I suppose one might ask 'whats the book time for pads and rotors'

When consumers lead with the "I have an E70 BMW...." you are just inviting "Oh, that model is a bit more involved, so it is $1750 for front and rear".

FYI, it is 8 pads and 4 rotors.

Rear rotors are 135 each, pads about 120 for the rear set.

So we are up to $900-950 for OE bmw parts for all 4 wheels (front and rear) And 240 labor to install

I will usually go through 2-3 front sets for each rear set.

And do keep in mind that these are OE BMW parts/prices.... Dave zeckhausen usually has equivalent parts for less.
