97z28 30th anniversary 6speed w full bolt ons and a full suspension - UMI 35/22 sway bars lcas panhard torque arm all poly non adjustable. Bilstein shocks and struts and BMR lowering springs.

Right after the lowering I noticed immediately the rear? End seems to not be planted over bumps at any speed an while accelerating from a stop if the road is rough the car will actually jerk forward in spurts from the rear hopping over the bumps (normal/light acceleration even). The ride is extremely jarring even for me and I love stiff suspensions, just can't stand the unplanted feeling its got now.

Is this due to the lca angle being jacked up from lowering and/or needing an adjustable panhard?

Could be a number of things. If those springs dropped you enough and the shocks are worn, they might not be dampening enough anymore. If you are having wheelhop on other occasions then that might be due to lowering and the angle of the lcas.

Could be binding in the Lcas and phb since they are poly ends on both sides and non adjustable. I have the same suspension and love the ride. Try putting the factory Lcas and phb back in.

Everything's brand new, all done at the same time so the shocks definitely are still good, about 10k miles on them. I also have big 18/19 c6 corvette rims I'm running with a spacer in the rear if that could e causing an issue.. The rears don't fit without the big spacer pushing them out far enough.

Remove the rear bump stop spacers (if you have them), go back to stock lca's or go with a set of lca's that offer joints or bushings which allow the lca's to articulate, regular poly bushings do NOT and will bind, causing nervous handling and a rough ride. Drop tire pressure to 32 front and 30 rear.

Ill try it out and report back

Could overtightening of the poly components cause the binding or make it worse too?
