The only thing I would be skeptical about is the difference in weight between the Grand Prix and the Riviera. But, with the 300+ pound difference, I almost wonder if that would lend these springs to be perfect for lowering.

If you look at the GXP it weighs close to the Riv, plus it's really front heavy so it SHOULD balance out.........

So the front springs fit in the strut. So what. What are you gonna do about rear springs? GP's have struts. Rivs do not. What good is a set of GP springs if you cannot use them all?

I know. However, for the sake of EVERYONE looking for different spring combos and lowering options, front GP springs are useless. No need for people to get the wrong idea and just start buying stuff that won't work.
That is all

Sorry... Just figured it should go in the lowering springs thread since some people might like a slight rake to their car, raise/lower the rear with the air shocks, find something that works on the Lucerne and adapt it or go completely custom....

Beautifully. It handles amazingly, you can just feel the whole car rotate where you want it to. Ride is a bit firmer but less bouncy. More comfortable because of that IMO.

Figured I would post an update after a few months of use. The ride definitely got firmer as the springs settled it. It's not horrible, comparable to maybe a G35 or Camaro or something. There is a little bit of vibration whenever you accelerate at a medium pace due to the axle geometry not being perfect, but if you take it slow or really hard there are no vibrations. Car handles really well, can keep up with my friends MR2 through the larger and faster turns but through the slow tight turns it just can't compete. No rubbing issues or any other issues so far.

What year grand prix spring are those? Does anyone have a part number? I am going to be doing the suspension soon and I'm getting rid of the factory too soft nonsense.

I can barely get a jack under my front sub-frame as it is... Lowering?

Well does anyone know how the Riv's auto-level feature works?
Yes, there is a level sensor that signals a small compressor in the right side rear to inflate or release air to the air shocks in the REAR only. Not uncommon for the system to be troublesome. You will need an FSM to diagnose problems with it.

IF you put STS sway bars on and Gabriel shocks/struts that will get you a stiffer 'touring' suspension. You could contact horseheadspickapart.com and if they still have the parts they would have a yardman pull and ship you the front and rear bars off my old Riv (which is not there parting out). Ask them to give you the links too, they are Moog HD with some sort of nylon or poly bushings, work very well
