    So I swapped out my rear ground force springs with progress rears cuz i wasn't into the rake. Thought I'd make a how to. I apologize in advance for the blurry pictures. this camera's tough to use in the dark.

    [​IMG]:doublepuke:

    what you will need:
    [​IMG]
    19mm deep well for wheels, 18mm shallow for shock bolts, impact gun or 1/2" drive ratchet with a breaker bar, jack, jack stands
    not pictured but optional: torque wrench, pry bar, 12" 1/2" extension


    [​IMG]
    put the car in 2nd or reverse. jack up the rear by the cross beam on the solid rear in the middle. both wheels will lift off the ground. remove your wheels with your 19mm deep well before lowering the jack but position your jack stands along the pinch weld. you want the suspension unsprung.

    [​IMG]

    remove the wheels and lower the car onto the jack stands

    [​IMG]
    you will see this.

    [​IMG]
    you are now going to remove the top shock bolt with your 18mm shallow socket.

    [​IMG]
    push down on the caliper. give it a good shove and the springs will free from the top perches.

    [​IMG]
    feel free to remove your springs.

    [​IMG]
    You can come up with your own method for this, but I found using a pry bar against the bottom coil perch is a good method of getting the pesky thing undone.

    [​IMG]
    keep shimmying, it'll come out.

    [​IMG]
    same with the bump stop. like my work shoes?

    [​IMG]
    now put them in your new springs and push like a woman in labor

    make sure you read your spring manufacturer's manual to figure out which side of the spring is up. the bump stop goes in the top.

    [​IMG]
    position the bottom of the spring in the perch.

    [​IMG]
    now get the top in there. the other side will be a pain because the opposite spring will want to pop out as you install it, so find a medium where both springs will stay positioned.

    [​IMG]
    should look like this

    [​IMG]
    jack the cross beam up. the sprung suspension will lift without the car.


    [​IMG]
    line that sucker up so you can get the bolt back in.

    [​IMG]
    almost there

    [​IMG]
    what do we do here?

    [​IMG]
    halt! hemmerzeit! lightly tap the shock into position.

    [​IMG]
    start the bolt off by hand

    [​IMG]
    couldn't find the darn torque specs for that bolt, but 100 ft/lbs sounds good to me.

    [​IMG]
    you know what to do.

    [​IMG]
    throw your wheels back on and lower the car. wheel torque specs are also 100 ft/lbs

    done-zo
    new springs take about a week to fully settle.

    Sweet how to man, have heard however that jacking your car by the torsion beam (that cross beam) can cause it to bend and/or warp, thus having an effect on the balance of your car.

    i can see where you're coming from. i haven't had any alignment issues and i do alignments often since it's free and i do them myself. I should add if you want to avoid this risk, jack it up from either side at a time from the pinch welds just to be safe. feel free to chime in at any time.

    good point, avoids having to re-align the top of the shock with the caveman technique. can't get an impact gun in there though.

    i did the same thing. by removing the botom bolt you might be able to leave the tire on.

    ff_drift_lol have you had a problem with the springs popping off the pads when you jack the car up? my progress springs do

    not at all, that's pretty odd. they should hold themselves in place.
