shock for weight in rear
 

I have an 02 ss and the rear end sags a slight bit, this could be due to my sub box and two 12“ subs and amp. The car only has 68k kilometers on it but what shock or spring could i use to compensate for my extra weight back there? Will bilsteins do the job? I know that most people go with the lowering spring and shock combo but i do not want to lower the car at all, if anything i want it higher ha. With my longtubes i have enough clearance problems driving in this area as it is. Any suggestions would be greatly appreciated. Thanks!

do you still have the spring isolators in the back? If not, that can give you an extra inch or so and really make the *** end stand up

Shocks have nothing to do with the ride height. Your car has saggy spring-itis.

I have no idea i will have to take a look, i have never touched the suspension since i got it. The rear shocks were replaced once by the previous owner. What are some spring suggestions then?

a set of stock springs/isolators would do you well to be honest, but check to see if you have them first

These fit inside the coil springs and are an easy inexpensive way to level your car: Air Lift 1000

Sorry I have been gone for a while but are the spring isolators on the bottom of the springs? I took a quick look under and didnt see anything but maybe I just dont know what they look like on these cars. Thanks!

What Camaro 69 said, plus if you have stocker orange de Carbon/Delphi shocks -- replace them as well for better damping. Be sure to check your bumpstops as well.

As I recall, the rear spring isolators are above. You might find this interesting, but you will want a stock unit which will be thicker:

what is the measurement from ground to the fender at the center of the wheels. front and back

Okay I took measurements on all four corners and this is what I got.
Driver side: Front - 27 3/4
Rear - 27 1/2

Passenger side:Front - 27 1/2
Rear - 27 5/16

This is on 275/40R17 tires(which are pretty worn in the back and should be rotated right away I should add). But seems that my car also leans to one side, not sure what that is about either.
