That's not too bad. I've just done it myself on my 6th gen. The installation for rear rotors and pads are a piece-a-cake on the 6th gen. Assuming good parts @ about $40-50/rotor and $30-45/set of pads, $215 isn't too harsh. Is this the dealer or some crummy big-o's? If it's a Big-O or Les-Schwab or some goofy corner tire place I doubt they're putting the best parts on. Probably raybestos or some brand-X rotor and pads. But if they put the good stuff on (Brembo, Akebono, Hawk, etc.) or even just OEM then I'd say you made out ok.
