How much do you need the axle dampner on the rear suspension? I have 275/45/17 nittos on a 17x11 thorq thrusters on the rears, they use to rub the axle dampners. When I got the car lowered I asked for the axle dampners to be removed. A guy at Ford said that the axle dampners don't do anything. It's suppose to prevent your axle from turning. I've had situations where I'm doing like 90 mph on the highway and I approach some bridge where there's little lip where the concrete meets the asphalt. The rear end just jumps up, it's almost to the point of losing control of the car. I have kyb adjustable shocks all around.
