I use the colony park HD coils (TRW Part # CC819), and they work great!

Add some air shocks to decent springs and you can adjust the height in the back. I have standard cargo coils and it makes the car level with no weight in the back. I can add air to the shocks and it firms up the ride a lot and gives me more lift if I want it.

Nick, go with the TRW CC819s only if you're gonna be hauling lots of shit around or you just want your car nicely raked all the time, this way whenever your load it up most of the weight is still supported by the coils. If you are gonna be playing with the ride height in the rear a lot then do what Thain said, but also add a compressor from a TC and hook it up to an electric switch so you control it manually :evil:

Fuck yeah!

[Nick52284]

then thats what just got ordered, lol, i'm gonna attempt to do it myself, a few questions first:

1. how hard is this job to replace the springs? and is there any type of procedure to follow?

2. while i'm under there is there anything i should check for being that the car is old, and what about the shocks?

3. i only have basic hand tools will they be sufficient for the job?

thanks!

Hell ya! Just jack up the car and place jackstands on you frame and then put the jack under the "pumpkin" of the differential. Be sure not to get the cover or it may bend it and cause a leak. Then jack up the rear end, unbolt the lower shock bolts and lower the rearend down slowly with the jack. Simply pull out the old spring and put on the new springs. You will need new spring insulators too if you haven't got them already. They are part # CC-100 and you need 2. They are a couple of bux each. When the new springs are in place simply jack the rearend back up and re attach the lower shock bolts. They you are good to go.

Nick, you'll be best off to:

1. jack the rear of the car as high as you can and place it on jackstands;
2. put a floorjack under the differential and lift the axle a little;
3. loosen the nuts that hold the shocks to the axle (the front ones, use 19mm socket) and slide the shocks off the pins attached to the axle;
4. slowly lower the floorjack allowing the axle to drop until the springs fall out;
5. scrape the old rubber insulators off the frame (they sometimes get stuck on it and don't fall out with the springs), put the new springs and insulators in, and carefully start lifting the axle while holding the springs in place. There is a specific position of the pigtail that needs to be observed, so get a buddy to help you out here - make him/her slowly lift the axle, while you hold the springs and insulators in place. Also your new springs will be shorter than the old ones, but they are much stiffer, so don't let size fool you

Now all that is good if you can take the aforementioned nuts for the shocks off, mine were so badly rusted that even a 1ft breaker bar wouldn't loosen them. For that reason I'd suggest that when picking up your springs you also rent a spring compressor, most stores like Autozone will let you do that for free (except for small safety deposit you get back when you return the tool). That's what I had to work with when installing my CC819s, it's a lot of wrenching and takes about 3 times longer then the first method, but can be done and the only special tool required is the compressor you just rented.

If you can get the shocks off the axle it's a good time to replace them, many people here are very happy with the police-duty KYB-GR2s, and they can even be had with airbags so you can run a self-levelling system if you have one. If you're about to do that job better make sure you have a big sawzall with a long blade laying around, get one from a buddy if necessary - the nuts on top of the frame can be a bitch and a half to take off, I ended up cutting mine off.
