Tubular A arms slightly too wide!

Maybe CPP would prefer to see their company''s name associated with good customer service, rather than poor quality control, and poor customer service on the internet. Give them an opportunity to make it right.

Exactly. And this isn't likely to be the first time they've heard of it.

I do agree on the quality control but I would have no problem bending them cold, if a weld brakes that's a very poor weld and I wouldn't want them on my car, I work with metal and have done a lot of welding and things moving when they cool is always a problem, I also have a Hossfeld #2 heavy metal bender and have bent many thing including leaf springs. Everything is bent cold.

It's not just about a weld breaking though. You have a constructed arm, with joints, different thickness metals, maybe even different grades of metal. Where is it going to bend? Who knows. In the pictures you can see there's a web/gusset welded between the arms. So, where are the arms going to bend in that press? At the ends of that gusset. The tube could kink right there. Not only would that mess up the geometry, it would significantly weaken the arm.

Bending something like a leaf spring, with a constant composition and uniform metallurgy, is totally different than bending something that is constructed. Heck even bending the stock UCA's is a far better idea. At least they're fairly uniform, and they do flex.
