Yeah, I emailed Ace about it. My pivot cups weren't stock either, they were the riptide custom ones that cost me nearly $15 and the first time the pivot hole started getting warped on the actual baseplate and it ripped through the urethane. Riptide was kind enough to send me a pair under warranty, they have amazing customer service and are super friendly, so I highly recommend those pivot cups. But yeah, as far as Ace goes...I'm bummed on walking away from them. If they end up making it right and I get a set that doesn't break I'll change my mind but I'm not getting my hopes up too much. The replacements will still be the same old recycled Chinese aluminum.
