I am using Eibach Sportlines. I'm bottoming out terrible. Should I trim the bump stops?

 

You need new good shocks. Do that first. Do not trim the stops.

 

It has new KYB AGX, I only have an 1/2 inch in the rear before the axle hits the bump stop.

 

the unfortunate thing is ; people lower their car , and it looks great , AND THEN they discover their car is not suitable for real world driving. raise it back up , deal with it, or only drive it on the track

 

By chance do you have stereo equipment in the truck area?

 

Yes. Q logic box with 2 kicker cvx 12in subs. Probably my problem. Lol

 

Yep, bought my car from a friend who was building it as a weekend cruiser/track toy. Looked and drove great for that purpose, terrible for the wife to daily drive. I've since removed the lowering springs and put back in factory springs. Doesn't look nearly as good but rides much smoother.

 

Eibach does front springs reasonably well.

What rear spring cushions are installed in the car? OEM are fairly thick. I think there were thicker ones in some 4th gens. And some people lower with the heater hose mod.

The CC635 cargo coil has held up well for me in multiple cars and both trimmed and untrimmed. But don't rule out going to a used pair of rear coils from a salvage yard.

I'm not saying the spring rate of the rear Eibachs is the best, but just explore all options first.
