    QA1's.. FE4s.. FG2s...

    I saw another thread about someone running QA1 shocks and then the car coming out lower afterwards. I thought this was the job of the spring... What gives..

    Also, I am looking to replace my FE4s with something adjustable. I want to retain all my factory looks and ride..

    Also, anyone else with a set of front and rear strut bars notice the ride is harsher? Bit more firm out back than it used to be?

    I still have stock FE4 shocks,
    BUT I do the have the rear strut brace>>>>> no change in harseness of ride due to the bar..
    i have the hoch sway bars and car feels MUCH better in the corners...

    I too am figuring out QA1's too......wish my FE4 would fail...

    FE4 and FG2s, the rear shocks self adjust. I think the QA1s are actually shorter than the stock shocks.

    I went from FE4s to FG2 and ground control at the same time. Ride really isn't too bad, and it handles much better. You probably have MUCH better roads than I do in NYC. I'm sure the ride wont bother you. If you want stock height, FG2s are the way to go.

    Mine slammed down about 2 extra inches in the front and 1 in the rear with simply swapping the FE4's to QA1's.

    You did a spring change, right?

    Re: QA1's.. FE4s.. FG2s...

    What is a better strut to go with fe4 or fg2 or the qa1? I have a maggie on my 05 and about to order some Ground control Coil Overs. I think i Have Fg2s on the car now. I plan to lower the car some for Handling. Not really sure what a FG2 and a FE4 is. I think the FE4 is the strut it self and the FG2 is the complete strute spring and everything but i could be totally wrong. Can you help me understand all this and guide me to what the best route to go?

    FE4 and FJ2 are the shocks and struts "combo"
    Most V's came with FE4, but can could order the car (or buy the FJ2's) with the upgraded/firmer FJ2 shocks/struts

    I really like the feel of my FG2s but I'm not sure they are worth the $$$ when compared to the QA1s and the longevity...

    I have less than 40k on the FG2s (no racing and no pot holes) and the fronts are shot. The kicker is GM doesn't want to sell replacements unless you buy all 4!

    You can get FG2 shocks separate. Front 88962952 Rear 88962954.
    These part numbers are for one shock not pairs.

    ok i'm gonna finally order up my qa1's....

    question for the guys running them... i am going to run factory springs for now (even though ride may suck). if i order the eibachs can i run them as the factory ones are ( strut in front and non-coilover in back)? because eventually i want to get GC or another type of spring

    Ok so

    QA1s lower the car - which is totally unacceptable.
    FG2 are firmer / FE4 are stock

    anyone else make good replacement shocks cheaper than a grand? Doesnt that seem excessive to anyone else?

    I guess it ought to seem excessive, but I used to spend 2-3 times that on motorocycle suspenders.
