I had a Forgeline lightweight race wheel that cracked. Forgeline's customer service was unsatisfactory. I eventually got it welded but it was never the same and eventually I had to trash it.

In contrast, I also had a cracked wheel from CCWheel. They sent me four new centerpieces even though only one had cracked. CCWheel's customer service rocks. I am still running those wheels years later. If you're looking for a wheel I strongly suggest ccwheel.com

Neither of those wheels were powdercoated.
