What do you think about Zimmerman rotors intended for an everyday driven, up to speed limit car with no abrupt braking maneuvers, as in a race competition ? Would you guys install them on a GLK as an alternative replacement or you will go with something else, and by the way there are no cross drilled Zimmermans for the GLK, or at least I have not seen yet !?! Wow :eek: .... my answer to your kazillion posts is the same. No... They'll crack no matter what application... (it just may take a little longer off the track) because they're made of cheap iron and they're cross drilled. No one in my circle uses cross-drilled rotors anymore for this reason... they're so 80's anyway!
So that all important question who makes the best rotors without going to $1K ceramic rotors? And yes we want to know if Zimmerman is up there. No... they're not up there! And I did respond to his "simple question" with a simple "no" along with an attached photo. Then he wished to know if it was fair to condemn all Zimmerman rotors, even if they're not cross drilled? I then answered in the affirmative. But he wished for more, so I took the liberty to explain how complex it was to make good quality cast iron rotors that directly translates into higher costs. And that cheap iron can be detected by a good mod jobber or mechanic at the time of purchase, that is if they know their stuff. If not, if you're an amateur relying on looks only, you will be ripped off. So you get what you pay for.
I donnu about the zimmerman rotors but just to let you guys know that the rotors I placed on my car were bought from ebay but was and those where used everyday going through city traffic and downhill grades and worked better than the OEM rotors.
