Resurfacing Rotors

[porschenut]

Dealer quoted me $495 to resurface and redrill my rotors, is that too much? He said there's rust on them and has to be resurfaced to perform well.

How much rust are you talking about? Mine rust after every car wash but the rust if scraped away with the first application of the brakes.

Resurfacing the rotor will greatly shorten their useful life. I would suggest that you get new rotors if they are rusted that bad. You can buy a complete set of genuine Porsche rotors for about $650.

Good luck

Hmm... how many miles on your car (rotors) now?

Porsche rotors have very little extra metal for turning. If there is much wear most shops will refuse to turn them (because they will end up below spec).

New Dealer rotors can run you $112 to $120 each, in my experience.

It's not very common to resurface drilled rotors. Rule of thumb is replace drilled or slotted rotors. Porsche rotors are drilled through. This takes away from the overall volume of the rotor materiel as compared to standard rotors the same size. Porsche does over do their brakes, which is goodness. By reducing the metal mass even more, actually weakens a drilled rotor. There are limited shops who will do it. But for the most part it's not recommended.

Be more specific on the rust issue.

I would not resurface your Porsche rotors just replace them.
