I have tracked my car with, and without, a strut bar. Personally, I think you can't tell a difference in rigidity. But then again, I'm not running monoballs.
So why did I buy a brace? So I could crank in some extra camber.
So why did I buy the dual setup? It was the same price as the single bar. I found out that the second bar actually makes it harder to crank the towers in.
