I measured the rotors. Minimum 30mm front, 26mm rear. They all have a noticeable lip around the edge as well. 1 in Colorado, 1 in Arizona, 6 in Houston. Admittedly, I only measured 2 in Houston because the other 4 had other flaws which dissuaded me from purchasing, but the prominent lip was still present. What I was trying to say is that it wouldn't be ridiculous to think that sdscardino might need a full brake job because I've seen it needed on several GT's with less miles. But definitely do not pay the outrageous dealer service prices.How did you determine that they needed replacing? People must drive hard in your area!
