Glad they work for you.

I didn't state those specific rotors are only for appearance. You stated that AMG only made things that gave better performance, or they wouldn't sell them. I countered that by pointing out that they also sell style accessories. Accessories that are just for appearance. QED.

Those particular rotors may be of a larger diameter, I don't know. It would be a reasonable assumption. If they were larger, they could certainly give better performance. If as a result of being larger, they were too heavy, they could also be drilled, and actually optimized to be drilled when the cooling fins were designed, in terms of layout, thickness, thermal fatigue, etc.

But that is completely different than taking a stock sized rotor with a standard vane design and drilling it. Even if you then put an AMG badge on it.

AMG sells steering wheels. Do those steering wheels make their cars corner better?
