What it comes down to is that the rear bar is sufficient for the stock setup and any average driver won't have the skills to push the car when a larger bar is added. I'm sure race car drivers would love the lack of roll, and would be more likely to eliminate the tailhappiness that is added.

I know alot of people on here complain about understeer, and i would think a larger rear bar would help make their car more balanced. I know I haven't had that experience tho, as my car is slightly tailhappy as is, even with a 265 tire.
Very imaginative, but no. Dinan and HPA Shop are not idiots. Real race drivers tested the various swaybars in real cars on real race tracks. Theories are good, but facts are better.
