The Pfadt Camaro sway bars required major engineering changes from the factory bar package to eliminate the notorious under-steer. Basic vehicle dynamics say that to eliminate under-steer you must increase the roll stiffness in the rear of the car - our rear bar does exactly that. That's how we achieve such great balance. If a sway bar package offers huge increases in the stiffness of the front bar, your Camaro is going to suffer from increased under-steer compared to the OEM sway bars!
