Demonracer, I read the ENTIRE post. It's a race part. It's fragile. You can fatigue aluminum by bending it back and forth and break it. It's a small tab. You can fold it over with your finger and break it off. And it's there on purpose.
You pays your money and you makes your choice.
A real PSA for someone wants to run these would be to show how to install them without warping them...
