you get "axle tramp" when you accelerate hard as the axle winds itself up on the leaf springs so tramp bars are located from the axle facing forward & welded to the chassis & they pivot at the axle & the chassis. A "panard rod" locates on the axle & lays across the axle & bolts to a bracket on the chassis & stops the axle moving sideways. I beleive the kit for the capri bolts to the leaf spring mounts so is alot easier to fit but is supposed to be a good bit of kit. Any way of stoping the axle moving will make a big difference you will notice. & tired rear shocks won't help much,my escort is fairly hard suspension & handles alot better on hard setttings than soft,but not to hard
