Question Just Installed my brand new KYB AGXs and im bottoming out

I just installed a set of adjustable shocks on my 99 camaro an i still feel a banging when i go over bumps or hit dips and wqhen i turn left i feel multiple bangsfrom the left rear tire.. I currently have eibach springs on the car now.. could it be a bad spring? or would a missing sway bar ling cause it?

Hotchkis springs.. Pick one..


And get under there and check the basics. Some people have broken KYB shocks and had the same issue.

I would bet it's not the springs OR the shocks.

Meaning the banging was there before the shocks, which rules them out. And while we all know Eibach springs are not ideal, besides sagging I have never seen a spring actually fail on these cars. It could be something as a result of being lower, but it's not the springs fault in particular.

I would check for a loose panhard bar bolt, lower control arm bolt, torque arm bolt, support the car on jack stands and wiggle the catback around, make sure your bumpstops are in place, and make sure your swaybar endlink mounts are not broken

ok thanks ill check under today.. I am also missing a bump stop on that same side (left) but i have a bump on the right side and that side has bottomed out a few time as well since i installed the new shocks.. Are lowered cars suppose to have bump stops?

I also had a memeber who had the same issue and when said when he looked under the car he was missing a sway bar link.. Could a missing sway bar link or bad sway bar bushing cause this?? I really dont hope its my shocks due to the fact that ill have to return them an I dont want to go threw that whole process.. Im even thinking about just buying a whole new set of springs with about a 1.5 drop.. Right now im running Eibachs..

Mine used to bottom out too come to think of it. I chopped the bump stops 1/2".. Problem solved. Driver's side = more weight on it with the driver in place.

I say panhard or LCA came loose during/after install. Also check and make sure the shock bushings that go through the body are in the right way.

The Eibach spring rates are to soft for the available compression travel you have.
I once had Eibach springs and had a rear spring bend after a couple of yrs.
IMO, get better lowering springs, I doubt it's the shocks.

You have 3 options:
1. Higher spring rates.
2. Less drop.
3. Higher springs rates and less drop.

im going to install a set a stock bump stops on an see if that will lighten up the bumps.. My next step is to replace all the shocks all the way around.. Deff a shock that will work with a lowered application.. if that still doesnt solve the problem then looks like ill be changing all the springs as well.. after that at least my suspension would be half way done lol

Ahhh yes, you're experiencing a very common issue with this combo. Every now and again, you will find a person that says this combo works. It really doesn't. KYB shocks work ok as a replacement for factory shocks, but they really can't handle the abuse used with lowering springs - especially not an Eibach. So installing our springs won't solve your problem...it may reduce it, but it won't solve it. I think a good set of shocks would be your best option here, if you ask me.
