    Since the search function on all relevant wbody sites is horrendous......

    I'm looking for springs for the rear that'll raise or keep stock ride height, but also be stiffer.
    Similar to the pedders zero drop springs for GTO's.

    Need as much spring rate as possible without blowing $700 on coilovers.
    Would prefer to raise the rear an inch or so if possible.
    Any ideas?

    I think the intrigue springs raise the rear up.

    Well it may be a bit out of what you're looking for but the kyb replacement struts come with springs that are stiffer than stock, and raised mine up a good inch, inch and a half from where the old 113k rear struts were. Here's a comparison of springs if you're interested

    2002 Grand Prix GT N/A 127k - Same as 06 Plus: Trans Cooler, DIY Aux Input, LED lighting, Suspension Upgrades, Tint, Retrofits.

    I'm thinking of going with the intrigue springs and a spring spacer to raise it an additional ~1.5"
    Should bring it up about 3" from where it sits atm.

    Or just throw a spacer on the vogtlands that are on it now to retain the higher spring rate.

    if you don't like how high the front springs on our rear struts were for the turbo regal....you can use lowering front springs on the rear and get the really high spring rate but the nearly stock or only above stock height...ours was raised nearly 3 inches with comp G front springs on the rear struts

    Now that sounds like something I can get behind.
    Right now I've got AGX/Vogtlands on the rear… Maybe just order up some front vogtland springs and put them on the rear.

    My aluminum coil overs on the front are awesome.
    The front air dam nearly drags on the ground when the back is cabled up.

    id almost suggest OEM fronts with a coil cut off would probably be a good bit higher spring rate as well as only a little "donklift"

    I know you said you weren't wanting to blow a bunch of money but you could make coils for the rear for not a whole lot honestly. You could make them yourself for under 200 bucks.

    Springs are roughly 40 a pop. $80
    Sleeves are about 20 a pop. $40
    Adjuster nuts are about 10 a pop. $20
    Top hats are about 10 a pop. $20

    Reuse your AGX's and mounts.

    So roughly 160 bucks plus tax and shipping. Should still be right at 200 or less.

    Just some food for thought.

    Has anyone ever done Vogtlands up front stock spring in the rear? Wonder how that would act.

    I tried this with longer KYB struts for a Regal on the rear. Once I lowered the rear end down, it sat the same height as my '04 did before. Using 1.5 inch spacers got it higher. But you can feel the bumps in the road a bit more now.

    Adding the strut tower braces helped a bit in stiffening the front and rear suspension a bit too.
