Does anyone even make lowering springs for these cars yet?
I cross-referenced the front a rear Springs with a G8-GXP and they came up different part numbers than the SS for front and rear springs. I would be scared to even try a G8 lowering spring for these cars.
The OE springs WILL be different for G8/VE and SS/VF. The SS weighs less, so the springs are necessarily going to be different to provide the desired trim/ride height established for production. GXP & G8 GT actually use the same production springs - it's shocks & rear sway bar that differed, mainly, along with the wheel & brake package--tires may have been specific to GXP, too.
While this is not an absolute answer to your question, the
Pedders Australia listing for VE & VF shows the same springs (from Pedders) work on both platforms. Assuming this is correct, it also means the other various spring suppliers (H&R, Tien, etc) offering a VE spring should be considered viable for use on VF. Until someone has actually tried it, this research is not 100% valid.
Since VE has been around longer and has more variants, there are more spring packages offered--not just for lowering, thus the greater number of products shown--I could have not listed them, but if you compare only the LOWERING springs, you'll see the same PN's listed for both platforms.
Many G8/VE cars owned by "enthusiasts" have gone to true coil-over setups--including adjustable shock valving, and adjustable ride height. There are both advantages & disadvantages to that, but I sense the owner group here is not, for the most part, looking to go hard-core to a true track setup that coil-overs is one of the core essentials of--that will come later, after warranty is ended, cars are in 2nd owner's hands, etc. Just replacing stock springs with aftermarket parts that provide lowered ride height will be most common, for now.
Here's several examples (pictures) of VE and WM (Caprice) lowered - WM uses the same Pedders lowering springs as VE/VF. There is no photo of a VF model shown at this time.
VE sedan
VE wagon (note that rear springs are different, specific to wagon)
WM sedan (listed as VM in error)
NOTE to Cajun G8 - George, here's the 20x8 SS wheel in silver on a Caprice!
If you dig deep enough on
CP's website, it will take you
here - I defer to CP on any additional comment/advice as far as using any of the products he's got listed there. My use of the Pedders information is not an endorsement--it was simply as a reference. If it's not correct, I'm not responsible!!!
Here's spring info pulled from Pedders (AU) website:
