Front rotors
You don't have to be a track rat to own a GT3. Don't lose too much sleep over it. There are plenty of GT3's on the market. You don't have to get this particular one, especially if you doubt how the car was driven/cared for. There are a bunch of GT3s on Ebay in all colors, options, etc. Let us know what you decide.

Although, there are many for sale, most are still too high, imo. I have only seen a very few in the $90s. Many of the higher priced ones don't seem to willing to negotiate. Personally, I think that the low to mid $90s is about right.
forty, for front engine setup, fronts take most of the beating. for gt3/rs, the weight and brake bias is towards the rear (not sure how bias is set for reg 991's), which makes the rears take more punishment (vs. front).
911dev, I think toad hit the nail on the head. Regardless, you can always have seller pay to replace rotors & pads (deduct cost from price).

Laguna_Dude, that is on the table right now.
I realize that the other 911 variants have Porsche's recommended break in periods of 2k miles. Without starting a bunch of banter over the engines being broken in at the factory, etc... does the GT3 have a recommended break in period as well?
What kind of rotor mileage should one expect from a well used, street only driven- hard street driven- GT3 with stock pads? I would assume 20k miles or more, or am I totally off base?

I will check the manual for break-in info. i bought mine w/3500 miles, so I didn't get new.
20K sounds about right. Others who have steels may be more helpful there.
Once the 997.2 GT3 is out, pricing on 997.1's will drop more. I am sure any of those selling would entertain real offers in the mid-high $90's (higher miles). Given how bad the market is, most would be willing to bite the bullet and sell in that range.

Could the previous owner have swapped his newer rotors with a mate to help him out since he was selling the car anyway??? Maybe the rotors you see aren't indicative of the way the car has been treated... Maybe even at dealer level if it's for sale through one... If the rest of the car is in great running order, just buy and change them... See if you can get a little more off the price of the car to help with their cost....

my 07 has almost 12k easy street miles and about 8 intermediate track days. all 4 pads are shot and front rotors not far behind. pads alone will cost almost $2k at the dealer. could have gone aftermarket for 1/2 $ but nothing has been available over 3 months so i gave up waiting. will go with slotted rotors when get around to changing them. btw, mpsc's will need more frequent replacement than brakes.
Second Opinion
I would like some opinions on this potential brake issue. I have a tenative deal struck on a low mileage used GT3 (under 3k). The car went to a Porsche dealer for a pre-inspection. The dealer said the car looked like new and that there was no evidence of it being tracked. (Not that tracking would void the deal.) Anyway, the DME showed no evidence of over revs and/or abuse.
The only issue that was reported was that the front rotors and pads had more than normal wear. My numbers are likely incorrect, but I think the dealer said that normal (rotor) run out should be .002 or so and that these these were .005, which is very, very close Porsche's max. recommended run out. He felt that it could be due to some repeated hard street driving/braking or possibly SCCA events. (which I am okay with, it is a race car, anyway, right?)
Of course, the dealer won't commit to mileage, but just said that the car could need front pads and rotors within the next 10-12k, maybe less if driven very hard. I mean it could need front brakes within 4-5k, right?
Is this type wear normal? I would expect GT3 rotors to last much longer even with hard use. These are of course steel rotors not PCCBs. Other than this issue, the car looked and drove like new. It's midnight blue by the way and looks incredible. It doesn't appear to be a popular color when ordered new, but it sure looks nice. I don't think that the color will hurt resale. I haven't committed yet.
Sorry for the long thread. I welcome any opinions.

Sounds like a great car, but have you taken it somewhere else for a "second opinion" on the brakes ? Sounds to me like the dealer is trying to sell you an expensive brake job...how could it be close to the max wear, yet still have 10-12k left ? I would take it to an indy and have them double check..I'll bet the brakes are fine.

After more conversations with the service tech, I learned that the rotors have 5mm cracks from the edge of the drilled holes which was caused by heat. 2-4mm is acceptable (2-3 is not unusual) according to Porsche. At 5mm or longer the car can not be certified, so if that was my consideration the rotors would have to be replaced. It is not that the rotors do not have useful life, it's that Porsche's CPO is very stringent.
The dealer did say that the pads have "well more than 50% life" and that the rotors could last a very long time (if not tracked hard); whatever that means on a gt3, lol.
My info was a bit off in the beginning. Anyway, wear is not the issue. Obviously, the car was run, like intended, at some point or another.

Back to your original question... Sounds like a fine car to me. So, the rotors might need to be changed in 10-12k miles, which could be a year or more from now. If the inspection says they need to be replaced, negotiate that in to the deal. If to be a street only car as you say, OEM rotors are all you will ever need.

I negotiated $90,500.
