Rear Springs?

[nitroracer]

What are the different rear springs availbale for boxes? Do they differ bewteen make and model or both - lincoln vs ford or wagon vs. sedan.

I'm looking for slightly stiffer springs but not the huge rake associated with wagon cargo coils. Would stock wagon springs do what I'm looking for? And where can you buy them from, I don't see any listed online.

You know you want the rake!

I hear stock sedan cargo coils are plenty enough... And from what i've seen... That is true. And you will be running regular shocks, right?

I suggest getting some KYB GR-2s on all four corners..

Edelbrock IAS!!!!!

Can I get a w00t!!!!

If you are going for handling, don't get the cargo coils. Get some PI rears or get some circle track ones. Wagon springs will give you a rake. The rates are posted in the FAQ and there is some more info in the one thread by Deuce...

This thread has some good info on autocrossing a box...

New cargo coils on my car didn't give it any rake. It sits just about level unless I pump some air into it. Ride is no stiffer than before, but the old springs were toast and I ran 100 psi of air to keep the car mostly level.

Yes, but you are in a lincoln with a ton of stuff in the trunk ;-)

I have PI rear springs, now that I see I have more option in the front, I thinl I'm going to be getting either 800 or 900lbs/in for the front

[DuceAnAHalf]

Pi front springs with one half coil removed give you about 825 in/lbs.

if i remember to borrow the book ill post the coil spring rate formula

with airshocks in the rear with 25psi, my cargo coils and rear bar, i hauled my 351W home from GA in the trunk of the merk, and the rake didnt change at ALL.

The 84 HD Cargo coils for a colony park are the best coils for that killer rake...

My car is air shock-less, probably has the original 91' shocks on it too. I was thinking a set of PI springs for all corners or maybe the limo springs that are rated inbetween.

Front Springs
Load Rates in Newton Meters & ft/bs
Stock: 77.1 - 440lb
Limo/HPP: 98.1 - 560lb
Police: 122.6 - 700lb

**Correction I just read HPP rear spings cannot be used on my box due to them being setup to be run with the factory air springs**

So how does police springs out back and HPP springs up front sound for a good handling daily driver?

I'm getting PI (160lb.) or custom (190-200lb.) springs. I want to firm up the suspension and get rid of the "retirement home" ride. This boat is going to be a cigarette boat!!!!

Why buy custom? You can get the springs... Circle track parts! Almost any rate you want. Double pigtail springs. 175lb-300 in 25lb increments.

:stupid: you can get springs for all 4 corners for about $200 plus shipping when coilsprings.com wants $130 for 2. check my thread at the top of this forum for springs.
