Just put a pair on the rear of my car. I bought the Ate brand since that is what was on before. I'll have to say they looked good out of the box. Nice and clean
However, the bleeder screws were overtorqued and were bent at the innner tips (crushed at the radial bleed hole). I reused the original bleeder screws instead. Also, pistons were installed with total disregard, since the raised halves were not aligned properly and one of the pistons must have come from a different brand caliper since it was plain flat!
Hopefully the piston issues won't lead to problems.
