Poorly engineered and/or installed suspension parts are a disaster waiting to happen! Kudos to you for having the perseverance to hang in there and do things right! Back when I was teaching high school auto mechanics, the kids were all suspension "experts" after reading a few magazine articles. It took a lot of education about proper geometry and the physics of automotive suspension and steering before they got to do anything other than replace standard parts. I didn't mind helping them, but the motto was "It's gonna steer and stop right before we talk about any 'go-fast' stuff!"
