370Z replacement...suggestions?

Maybe you're less picky, or maybe my car has a bad rotor. The right front they just cleaned up a tad, but the left front had to be turned TWICE before it was true. This time around, I'm going to ask for a replacement. It's only been 7K miles since the last time this was an issue.

They properly bedded them at the dealership when I had them re-do them. Took the car out, used an IR gun to measure temps, bedded them with a similar procedure as the GT-R brakes, although obviously not the same as it's not a GT_R. THat's what I was told. When I got the car, it felt great. Stopped awesome, and I could look at the rotors and tell the brakes had been bedded, or at least something had occurred, as there was definite pad transfer, etc. Smelled like it, too. GT-R tech did the work.

Either way, it's not dust, it's a warped rotor. If it were just dust, it wouldn't have taken a ton of metal being removed to fix the left front rotor, and just a quick clean-up for the sake of it on the right.

I tried re-bedding them the first time, 6 hard stops from 60, 4 from 80, drove around on the freeway until the rotors cooled off, never came to a complete stop. It only exacerbated the problem. This time? It's going straight to the dealership for a new left-front rotor.

trust me im pretty picky about the way my cars drive, matter of fact my little honda civic that i use as a daily driver is having the same problems with the rotors that your Z has, but since it's a beater car it's not really a top priority as long as the brakes work properly. On my Z though if that happened that would definitely annoy me enough to get them changed out, but that never happened with my Z even after pushing it pretty hard through the corners and using the brakes extensively. The main thing i always kept in mind though after heating up the rotors that much though was to let them go through a cool down period before i touched the brakes again.

You need to do way better than that, a couple stops from 80 is nothing. Also when you resurface rotor, you are essentially removing metal from it and making them less effective.

These aren't track pads. These are not track rotors. That is plenty sufficient to have cleaned up anything, if it WAS to be cleaned up, doing the above. Anyway, it's a moot point, **** should not have to be done on 10K mile old brakes when they did fine previously, and then again at 17K miles after they did fine after being fixed at 10K. I could understand if they were not right from the get-go, but this is a problem and it needs fixing, and re-bedding the brakes isn't the way, IMO, given what was found last time (one rotor needed turning twice as much as the other).

Anyway, you're right, which is why I want them to replace the LEFT FRONT ROTOR.

If it were just deposits, both rotors up front would have had a problem, they didn't, just the left front. Right front just took a light clean-up, left front had to be turned twice for it to be true.

I'm going to get the rest of my car (TPMS sensor, rear bumper) fixed at the body shop today, and deal with the brakes tomorrow. I doubt they will argue about replacing the rotor, considering it did the same thing at 10K miles and they said it was so bad off it needed to be turned twice, I think an argument for factory defect can be made, in the case of that rotor. Why isn't the right rotor messed up? Yeah...

Why is this an issue for me? It feels like crap turning into a corner when the weight shifts to the left-front. To me, that's an issue. Will it make the car handle worse/less safe? Nah, but screw that. Even my old 5.0 from 1988 had less shudder when I got on the brakes, I don't feel like I am getting what I paid for, and I doubt Nissan will argue.
