I just bought a Rear Brake Restoration Kit from Classic Garage. After I installed the new rotors I noticed that the holes in the rotor are significantly larger than the lug bolts (the holes are 15.2 mm; the bolts are 11.4 mm). I then measured the holes in the old rotors and they were just large enough for the lug bolt to pass through them. I'm guessing that the enlarged holes would cause the rotors to erode the lug bolts thereby making them unusable. The markings on the box showed the correct (I checked EPC) part number: 126 423 00 12.
Check out the photo. Am I missing something or should I tell the vendor that these rotors are unacceptable?
A quick update on the car: My mother gave it to me last October after it had sat for over ten years. I went through the "it sat for ten years " procedures and was able to take her for a ride at Christmas (though a caliper stuck and the brakes overheated!). In the process I've hooked up with Jon B, Alfred, Franz, and the other owners in Northern San Diego County. It's been a great experience so far - everything I fix makes it a bit more enjoyable to own. It's a beautiful original car, and I'm doing what's needed to make it safe and driveable. If you need pictures of "what's original" just ask. We lost my mother last month; at least she knew her car is being cared for.
