Just wondering if anyone has any pics of a Ground Control Weight Jack system installed on a third gen. I'm looking to upgrade my suspension a bit more, and wondering how exactly this sytem works, compared to a coil over system such as the one from PA racing.....

 

I don't have pics of the kit on my car, but it basically works like this:

Front: Each spring has a "hat" on top (you probably couldn't see it very well in pics anyway because it tucks up in the subframe) with what looks like a huge screw going down the middle. At the bottom end of the "screw" is a slot where you insert a long extension for a 1/2"-drive ratchet. The extension just fits through the large opening in the control arm, and you can either use a ratchet or breaker bar to turn the screw. When you do this, the "hat" basically seperates in two pieces -- the bottom portion stays snug on the spring while the top portion goes up or down.

The only thing I can think of that illustrates how it works is your basic nut and bolt. The bolt is basically the upper half of the "hat" as well as the large screw, and the nut is bottom part of the "hat." Hold the nut between your fingers (heh heh ... or find somebody to hold your nut) and turn the bottom part of the bolt with your hand. The top of the bolt would basically be pushing the car up or lowering it.

Once everything is in, you don't need to take the wheel off or undo anything. Just jack up the car, use the long extension with ratchet or breaker bar and adjust the ride height.

Each spring/hat assembly just mounts in place of the stock spring.

Rear: Each spring sits on top of a collar that can be rotated up or down on a threaded sleeve. It looks a lot like this:



Except without the aluminum hat, and the spring is a bit bigger diameter. The bottom part of the sleeve just rests in the same spot as the stock spring. These are a bit harder to adjust because the spring still has too much pressure on the collar after just jacking the car up. You have to undo the shocks as well.

Everything is pretty easy to install.

 

very well put!!! i just got my set of GC weight jacks and was wondering about how to adjust the front (their not installed yet)

 

With a 1/2" wrench, an extension, the right sized socket (i forget which) and a good deal of upper body strength. Reach the turning "post" up through the lower a-arm from below.

 

wrong. You use a 1/2'' drive RATCHET and an extension. no socket. You pass the extension up through the coil spring and into a square hole on the threaded shaft part of the weight jack. Twist it to raise and lower the vehicle.

 

#1. When I said 1/2", it was obvious that I meant the ratchet & you knew that or I wouldn't have bothered to mention a socket too (obviously).

#2 your right. No socket needed. Been so long since I adjusted mine that I forgot. However since the person that asked the question has his not installed yet, he obviously would have noticed before they ever went in.

 

9 years...lol..talk about ya back from the dead post!...
