It's not the build that's important, so much as the tuning and driving. There's a lot of racers who tune by the "hold my beer and watch this" method and they also run their junk well after it should have been put on the trailer and taken home to figure out what's wrong.

How many A-holes blew up their junk trying to get "just one more run?"

Unsurprisingly, these are often the same guys you hear crying about "weak parts" and "bad builders."

Girdles and aluminum maincaps are beneficial because they dampen vibration and add rigidity, which is good for the same reasons as with fixturing machine parts. Vibration=chatter and broken tooling. S/F....Ken M
