I love my 99 gtp sedan, but i hate the way it rides, i feel every little pebble in the road and i bounces sometimes. I have a gmpp sway bar and strut brace kit, which helped a lot, but now i think its time for struts and springs(or whatever their called, I'm new to suspension so be nice please.) Also, My rear end seems to sag a bit and I'd like to change that, if anything I'd like the front a little lower than the rear. Anyone have any different setup options they'd like to share? Thanks as always.

For struts I'd go with Koni AGX's and as for springs if you want to lower it a little bit and maintain a comfortable ride Voglant spings are the way to go.

If pot holes bother you, your better off getting all new oem struts and springs

KYB AGX's?

Haha oops I mean KYB AGX's lol

do springs wear out?

If you want a softer ride do not go with kybs or any after market set up. Best way is all new STOCK suspension

But do springs acctually wear out? would it make sense to replace them?

not really

I'll steal your fenders tonight.

Springs DO wear out. It's the reason why your car is sagging in the rear. Carefully look at your back tires and see if they are sitting at an angle (top of wheels pointing inward). If its enough to see, then your past the point of needing new springs. This causes uneven tire wear over time. Remember to get a full alignment after you lower your car to avoid uneven wear.
