I am a machinist by trade and I can assure you guys from the sounds of things AEM had a lazy machine operator that didn't like to check parts. Some out of tolerance rotors slipped through QC and to you guys they went. I personally would have just fixed them at work, but that isn't an option for most. I deffinately agree with taking this up the chain to AEM themselves if not Powerslot. They bought the business from AEM so in my eyes they also bought the problems with the earlier design and lazy workers.
