lowering using rear spring top shim?
for my VIN it shows 4 top spring shims
5 mm
9 mm
13 mm
17 mm
iirc the car comes with 13's
if they were swapped for the 5's would that lower the car 8 mm?
I'd like to lower mine but don't want the 20 mm (and the ride and potential alignment issues) the H & R's offer
I'd like to lower the rear a bit, the front seems OK
this might be a good solution
has any one done it?

Dropping the rear only with pads will look weird as our cars sits lower in the rear stock form. I actually had to raise the rear with 17mm pads after installing my H&R springs.

this is the parts diagram for my car, a 2009
item 8 is the upper pad, 4 is the bearing
it appears to have a pad, but unlike the rear only 1 PN is listed
the rear has 4, each a different thickness
perhaps the front could be shaved down 5 mm or so?
imo not worth the aggrevation of disassembly
the rears would be easy to swap out
some measurments from mine:
floor to fender lip: F 26.0, R 25.8 w/ 3/4 tank of fuel
tire to fender lip gap, measured with a string, level and steel rule:
F 26 mm (1.02"), R 24 mm (0.95")
So both are basically 1" for all intent & purpose, they are the same, I think it's an illusion that the rear is lower, mine actually looks higher, but measures the same.
I don't think the H&R's lower the rear more than the front, but the Eibachs do for many applications, to help transfer some weight rearward
tires OD loaded at curb
F 25"
R 24.85"
makes sense since unloaded OD is F 25.4 and rear 25 per mfg data and the front is lower pressure and carries more weight so would compress a bit more
To get a 'rake' reference I used the seam at the door bottoms from floor to middle of the seam measured at each wheel arch. I've seen lowered cars where this is almost level.
F 10.2", R 11.7"
1.5"/78" or 2% rake
If the rear is lowered 8 mm or 0.3" the rake would be 1.2/78 or 1.5%
I think the 8 mm drop would level the car out a bit and make the wheel/fender gap appear even (although the rear would be 0.7" vs 1" front).
I like the 'look' with a bit of rake and the front gap a bit larger than the rear
