I have zimmerman on all 4 corners of both of my cars, they perform amazingly well. I've put 35k on them on my W126....and about 22k on them in my W124, they stop like heck and last a long time.

My dad has them in the front of one of his W126's also, and they have performed well on that car too.

They have holes in them and you can feel the power build under heavy stops rather than fade. Its pretty awesome.
