I have 35000 miles on my car so I should be just having my rotors turned and the holes cleaned up on my Boxster S

The Eurpeons in particular are using thinner rotors than they used to. Most Porsche dealers do not recommend the turning strategy and that MAY be a money thing. However, my brake guy says not to do it with the Porsche, BMW and MB rotors.

Hmmmm!

Well....If I don't have the rotors turned then it leaves the grooves and pits in the rotor.

mmmm....??????

Well, they want you to replace the rotors each time you do the pads. In their mind, this is the ONLY way to do it properly.

Back in the day, turning them 2-3 times was fine, no?

With respect to turning rotors, you can have them turned until they reach the minimum specified thickness set by the manufacturer.

Seriously, the effects of running a rotor past the min thickness are: easier rotor warpage, or if they get too thin, they could break (literally) apart.

I not sure why some mfg recommend changing rotors with each set of pads. But that qould get awfully expensive awfully quickly for me. As I tend to go thru brake pads like water, between track events and auto-x's.

Good luck with your decision.

Oh, as a sidenote, I would avoid cross-drilled rotors if you could. Unless you like the bling bling factor. I'm not gonna get into a technical discussion here. But as an example, I can't think of one race team or series that uses cross-drilled rotors on their cars.

i'd go with the green brake pads. they work exceptionally well

I have a boxster S which includes the cross drilled rotors.....I guess instead of turned (placing the rotor on a machine that spins it around with 1 tiny piece that shaves it down) maybe the correct word would be grinded down?

?????????????

I will ask Hergesheimer how they "Turn" the rotor.
