Ever since Diamond was aquired their shipping and QC has been off the mark.I'm sure it will level off.

Aquired by management that do not know anything about making pistons, or the piston business. Key personnel that do will leave, personnel that can help won't be brought in. Machining, QC processes, and costs will be cut, and quality will suffer. CP got real busy soon after the below announcement, racers have seen this story play out over and over.
