So I am looking to replace my rear springs and I want to keep the stock ride height. There are two types of Moog springs and i do not know which one will work better for me. I am also going to be replacing the shocks with Billisen HD shocks ( front and rear). I only need rear springs becuase the front shocks already have spring in them. Which of the Moog springs, either the Cargo Control springs or the Replacement Coil springs?? I the main thing im looking for performance wise is that the rear suspension doesnt max out when i have a full car ( thats what happens now).

 

Yhea, help a brutha out ^^^^

 

Sounds like you want the cargo coils. These are variable rate springs. The replacement springs are constant rate springs.

 

What are the advantages of the variable rate springs?? Any Disadvatages?

 

I assume you are talking about progessive spring rates when you say variable. What this does is lets the car ride softer most of the time but as the spring compresses it gets firmer. Many people like this, but I feel a linear working rate is more predictable. It's really just user preference to be honest. I don't know what spring rates moog uses but I would assume they are close to stock.
