I just did my 60k service and this weekend or next I will do my brakes, flush the fluid, etc.

AFAIK these are the original rotors and they have a slight lip on the inside and outside of each rotor. More on the front than the rear but all 4 rotors do have a slight lip. I think they are still in good enough condition to simply put a new set of pads on and not worry about them until the next time my pads need replacing.

So can I have these rotors turned? If not, how much are new ones?

rotors that are cross drilled cannot be turned.

Measure them.

Why can't cross drilled rotors be turned? I've heard this before but no one has ever offered an explanation as to why.

Cross drilled rotors are harder to turn and in doing so often results in some issue in consistency of thickness. The cutting bit can be miss guided when hitting the holes. It's possible but not as easy. If you do decide to try, have someone who's done drilled rotors before. Often, it's simply not worth the effort.

Not sure what you mean by a "lip" in your rotor. If you have varying thickness that requires turning, you should probly just replace it. Measure the thinnest part of the rotor and make that that's more than the min spec stamped on the rotor or in the repair book.

Nice mic.

I had cross drilled rotors on my 280ZX Turbo and Nissan's Competition Dept. said they couldn't be turned. My dealer says the same for the 996.

Brakes have always been a Porsche strength and I'd be leery of deviating from the company line.....

When I brought my 2001 in for a routine service with 15,000 miles on it they called me and said I needed new rotors. I went down to the dealership and the lip on the rotor was barely enough to catch your fingernail.

The service manager told me it's Porsche policy to replace the rotors if there is an edge, I told him fine, then you pay for them. I made such a big deal about that they in fact did pay for the rotors.

No way a care with 15K that's never been tracked would need new rotors!

If you turn CD rotors they don't dissipate heat nearly as well, and in turn, the structural integrity of the discs are compromised.

It's a couple hundred bucks for new rotors. Small price to pay for safety (though I do understand the argument about not replacing anything unless absolutely needed).

Jeeze... talk about resurrecting an old thread.... lol

I turned mine no problem.

I just had the Porsche Dealer turn my cross drilled rotors. They said usually, there is not enough thickness to turn them, but after measuring the rotors, the Dealer turned them.
