Even if I leave the iso intact, a rear bar would be nice. The frame rails are solid so not worried about them. My main "gripe" is the way the rear of the car feels loose or wallowy and disconnected. Not sure how to describe it but you get what I mean. You are right, I like to have the ride better vs all out handling and it rides stiff enough as it is. It's the uncertainty on a curve, especially when first turning in. It always feels like the rear end lags behind the front, and then you have to correct by turning the wheel back because the car is suddenly turning too tight. I suppose, the poly spring isolators don't flex much and, there is zero wheel hop when doing spirited acceleration. So, maybe the iso delete isn't worth the money and work, in this case?
