Ideally I think you should replace rotors every time but if the rotors are well within spec and there aren't any cracks then it should be OK to just replace just' the pads. If I were you....I'd be looking to do the work myself using the DIY instructions and Video available here plus upgrading to lightweight two-piece rotors. You upgrade as well as save money.

I have been reading this forum's posts about pads and rotors and I think I am being led astray by a mechanic. But, maybe I just don't get it or am missing something.
My 2006 C4S has 59,000 miles on it. I do not track the car, and am not an excessively hard driver. I usually get an above average lifespan on my pads and rotors on my cars, so I am driving around riding the brakes all the time.
At 36,000 miles, My front pads were down to 3mm and so I had them replaced. The mechanic informed me that the rotors had to be replaced with every rotor replacement on the 997 C4S, so I had the front rotors replaced as well. The cost was $1600. (All Porsche Parts)
Now at 59,000 the fronts are down to 3mm again and the rears, which have never been replaced, are at 4mm. This is about what I'd expect, given the general rule of the fronts wearing out twice as fast as the rears.
However, the mechanic is saying that I have to do all 4 rotors as well. Total cost for the brake job with all Porsche parts: $3000.
It seems unlikely to me that I really need to do the front rotors again and do the rear rotors as well. I want to keep my ride in top condition, but I don't want to be a moron about it.
Should I just do the pads and call it good?
Thanks for your help!

I've done probably a hundred brake jobs while working for my dad in his auto repair shop so I come with a little experience. I've also turned countless rotors when I worked at Carquest Auto while in High School.
Basically, if you put 30-40k on a set of rotors they won't stay perfect...right. I'm sure you noticed the grooves building up on the face of your rotors over time. Rough and grooved rotors are not' an ideal surface for new brake pads. You really want a perfectly smooth surface for your new pads to brake into and that is why we always turned the rotors or replace them with new if they were out of spec.
Since we have cross drilled rotors on our cars we cannot turn them because the carbide tip used to resurface the rotor on the machine lathe would eventually break passing over all the holes. Therefore, replacement is the only option for us. If you plan to keep the car and you want to guarantee perfect like-new brakes at replacement time then I recommend replacing the rotors and doing a proper bedding. High performance cars deserve the best brakes or at least my car does.

This link below will take you to the Giro Disc web site. This is an cool upgrade but totally unnecessary since we already have great brakes on our cars. Most of the guys using these disc's are tracking their cars regularly. My car doesn't need brakes yet but I'll probably go with these lightweight disc's when the time comes.
Combine these disc's with a lightweight set of wheels for less unsprung weight...you'll think you're driving a GT3.
