Recently I added Eibach Sport-System-Plus suspension package. I love the way it handles now but the slightest bumps now and it bounces alot causing the axle to make contact with the exhaust. Any suggestions?

1.6/2.0 inch drop is asking for trouble. I never recommend going that low on a Mustang.

It is probably sitting on the rear bumpstops (among other problems).

Did you put shocks and sturts too. I know when my struts wore out my front bounced all the time causeing the body to drag in the front. So i went coilovers. But im 3in drop

Ya I did front and rear. The guy that put em in for me said it was normal due to stiffer springs.

What shocks did you put in and are they the right damping rate for those springs. under damped (to much spring rate for the shock) and it will feel bouncy. Might be what's going on

I agree...

How severe is the bounce up and down? Is it violent or does it just keep bouncing after you go over bumps? You might have a bad set of shocks/struts. The bounce typically would come from bad shocks. If the springs are too stiff, the car will behave like a jumping bean. Is there any clunk from hitting the rubber bumpstops?

What is weird is that its all "new" stuff from AM. Plus, its all part of Eibach's package so you would "assume" that the dampers and spring rates would match.

Can you drive it and have someone in a "chase car" take a video of the car behaving over bumps so that we can all see it?

You could also do a bounce test by pushing down on your front and rear of your car and see how much it bounces up and down. Then you can also get an idea of whether or not it's hitting the bump stops.

I dont see how 1.6 2.0 drop is that bad if done right. My buddies fox is 3.5 drop and mine is 3 at the moment but i can go 5 in drop. But i cut the bump stops off of mine

I havent had a problem with it yet. Only problem i have is dragging but i have skid plates so that doesnt bother me either. I want to drop it lower but pa hills and the local cops just dont allow that to happen

The bounce isnt sever. Its more like quick short hops at some bumps. Like at stop lights where you tend to get those series of rolling bumps like the asphalt has been bumched up from the whieght of vehicles stopping. when i get moving over those it hops. Once im over those it ok. The bottoming out tends to happen at the base of hill and the occasional unavoidable manhole covers and such. The hops are bearable but i worry about the bottoming out damaging the axle or axhaust.
