sighting

Dealer quoted 3.5 hours for the swap and flush. Even my cheap chop shop charged me 500 for the install.
as for the pads. the set i looked at was around 600 a set.(Think it was the Pagid Rs4's and that was a cheap price (1200 normally)
oh and you forgot the tax on all the above items..

Personally I would do it myself but most ppl won't.

don't get me wrong if i was around 40k or at the rate i am braking 30k and I needed new rotors I would be over this like a cheap suit but that would be because I needed new rotors. but unless you counting .. points of a second then its a very very expense mod for the output.

Your rotational benefit would be better spent on the larger rotational mass items.. like rims.. or those closer to the origin.. like a pulley.. under drive or not
