As Michael said, I had them on my previous 33R.
Very stiff for street, they really do make it handle amazing. Unfortunately, I killed front pair by driving it into a pothole, which is real shame cos they're really nice coilovers to use if you like stiff ride which I do, they could benefit with pillowball mounts as Michael said for direct ride feeling and shave 2 inches off the ride height if necessary.
Out of curiosity, what sort of tops do you have on yours?
