something I learned with other cars.
the shock choice can really affect how it rides.
I also learned the difference between HD and the Bilstein performance line.
HD has more "bounce"
Performance has more dampening, important if you have heavy "performance" springs.
For my 09, I don't want to mess with the way it rides.
It just needs to be freshened up, so I over planned to keep that smooth ride package.
I might end up replacing the springs, but for now I'm just doing shocks and ball joints...
If i were to do the springs, I would do OE.
And be as sure as possible that I was getting the correct "smooth ride/premiere" springs.
I have the PN's for my 09 saved.
Front shocks: 20765171 /aka 540-460
Front springs: 25876851
Rear shocks: 25871225 /aka 540-433 (calls out ZW7)
I don't seem to have the PN for the rear springs saved.
I had a slight lean, so I was planning to do the front springs at first.
but the new ball joints + struts on that side seems to have fixed it.
