Just kidding...not slammed, just slightly lowered (1").
The known lowering options are:
- Heico Selected Leveling Kit ($1,900 + installation) - Installation appears to be complicated and may require a VIDA reset. Off Road mode retains full height. Height adjustment is 30mm (~1").
- Adjustable leveling links (Ghostlinks - $225) - Easy DIY install, height adjustment is consistent across all drive modes. Off Road mode doesn't retain full height.
- Deflate your tires?
I'm not going offroad anytime soon and, while technically impressive, I think Heico's solution is too expensive for what it is.
I got the lead on Ghostlinks from MrJackNYC. He worked with Ghost Motorsports to develop properly sized links for his XC90. Fortunately, I was able to verify the sensors for the SPA XC60/XC90 are the same (including the linkage arms).
The lowest drive modes (T8), in order, are: POWER -> PURE -> HYBRID -> OFF ROAD. In POWER mode, my measurements (ground to top of wheel arch, level slab) were:
RR: 32.5" (I asked the dealer about this and the answer was "within factory tolerances" )
The stock linkage arms measured 42mm (inside edge to inside edge) and Ghost recommended a 5mm adjustment (front +5mm, rear -5mm) to achieve a 1" drop. It turns out the rear geometry is different and required a -8mm adjustment (RL: -8mm, RR: -10mm).
Height after adjustment is 31" (ground to top of wheel arch) for all four wheels in POWER mode. My initial impression (~15 miles) is handling is tighter (less body lean) and you do feel more bumps, but the ride is not anywhere near harsh. My lowered 2007 S40 with Eibach springs and Bilstein Pro shocks was harsh.
