Of the couple dozen ERAs that I have seen, live, with my own two eyes, I don't believe any of them were built by the owners -- they were all factory jobs. But I've had a lot of my car apart and I tend to agree with you. If you take your time you'll be fine. At the very, very end of the build, having four corner scales to set the corner weights will end up making a world of difference though in how it handles. ERA did that for me, and I subsequently checked them with my local club's scales and they were dead on.
