The problem with the CAP UCA's wasn't the design though, it was the welding and poor quality control. A lot of people never had any problems with the CAP products, myself included. I know of a few people that bought them from Mancini and didn't even know they were from CAP. I don't run the CAP UCA's anymore (upgraded to Hotchkis), but I still have their LCA's on my Challenger, and have had them on my car for almost 30k miles now. If QA1 is making the arms, I would think they would be much improved in both of those areas.
Still, it would be nice to see/hear what QA1 is doing differently as far as production goes, since that was the problem before.
