The rear springs and shocks and anti-sway bar from the '12 3.8 fit the '11 4.6 just fine.
The sway bar seemed identical, so there probably wasn't any need to change it.
The '12 springs had about 7 coils and the '11 springs had about 8 coils.
The '12 shocks were slightly softer.
The ride quality has improved, with less rear end bounce.
The rear ride height probably dropped around 1/8".
I was hoping for an even softer ride... you still feel every bump, but at least it doesn't knock the wind out of you while you're trying to speak anymore. I guess I would have to go with a buick or es350 if I want anything softer.
I'll now change out the front strut assemblies.
If that still isn't soft enough, I'll go down to 17" rims and tires when it comes time to replace the tires (assuming 17" rims will clear the calipers).
