I have sold a considerable number of Zimmermann rotors and cross-drilled rotors with extremely good success. I have found the cross drilled sport rotors to be very competitively priced as well as very effective in high performance situations with no warping found in most discs. This is especially critical in track situations and hilly mountainous environments.
I have also found the chamfered edge on the cross-drilled holes to almost eliminate cracking, as well as the holes themselves being designed and machined in during production rather than an after thought.
When your needs require a performance rotor for high stress and performance braking, my choice and recommendation would be the Zimmermann Cross-Drilled Sport rotor. For normal every day driving, I find the Zimmermann rotors to meet or exceed the OE rotors installed from the factory.
