But that's my point.
We have a picture in this thread of a 997 Turbo rotor that has widespread cracks in just 7000 miles of use. The cracks may have been present earlier than 7000 miles. We also have a picture of a 996 Turbo rotor with over 57k miles of use, and a picture of a 996 Turbo rotor with over 37k miles of use. Neither of these rotors show any cracks. I can't speak for Macster, but my rotors have seen extensive "spirited" driving, including many mountain runs (some in the rain). You commented that you were surprised that AndyMc's rotors exhibit the level of cracks they do given no track use, and in only 7000 miles. I am too.
That other equipment is inspected more often, and is held to such a high standard, because its brakes could be called on to decelerate a vehicle that weighs 450,000 lbs to a stop from over 200 mph, using their maximum effort (3000 psi of brake pressure), without failing. Oh, and with the lives of over 250 in the balance.

On the 996, Yellow Front and Black rear improves brake balance. The 997 cured this and using the same pads front and rear works better on the GT3 in my experience.
