I have almost 70k on my 2012 SV non sport and I am feeling the suspension needing a refresh. I am not using the car as a sports car as I drive 90 percent highway. I also have an S30 for twisty roads. I just a little less Buick feel more 5th gen SE feel.
Plan A: OEM dampers and aftermarket swaybar upgrades.
Plan B: Monroe OEM spectrum dampers and RSB upgrade.
Plan C: Monroe OEM spectrum dampers Eibachs and RSB upgrade. Least likely to choose.

 

Option b

 

Plan B sounds like the winner!

 

Or I can sell you my OEM setup off my 2013 SV that has 13000 miles on them. Still have them in my garage. PM me.

 

I think plan B can give you a good ride quality and handling.

 

What sway is the best bang for the buck? I know stillen stuff is good. Racing line? Anyone swap for a sport front bar?

 

Stillen is a good bar, but is not adjustable. It is 50% stiffer than stock.
RacingLine is also good, and has two settings: 50% and 100% stiffer than stock.

I'm not sure I have read of anyone upgrading the front bar. I'm not sure you would notice it, while the rear bar is a huge improvement.

 

i have the Sachs struts/Shocks with Eibach springs.. love the ride .. love the firmness.. love the handling ..not too firm but just right.. that did it for me.

i will be going with the Racingline RSB in the future.. they have the best reviews.

 

Option B will give you good results.

 

For what you are looking for, go with B. I'm not for sure how much better the Monroes are over the OEM dampers.

 

Option B install is today. Will have to wait a little for the rear swaybar.

 

Just got home. Wow, that suspension was beat at 67000 miles. Now sway bar and brakes.
