There ain't nothing wrong with Cal Tracs that a good four link can't fix In all truthfulness Cal Tracs are a excellent product and do a good job where you can't run a laddar bar or a four link or three link due to rules or space or budget constraints. I have owned and raced several different Dusters with ladder bars and I like them a lot I have freinds who have lighter weight cars with four link that work excellent, you can hook them up in a mud bog in the middle of a rain storm And I know there is at least one Cal Trac racer on here that can do that also on a nine inch tire The decision is yours
