The piston air lift system I built gives 4,5cm more lift to the existing 5cm (2") lift from the HotBits coilovers, so its nearly 10cm lift over stock. CV's don't really appreciate high angles, especially at higher speeds thus why I developped this system. The highest angles I get on the CV's is at full droop, about 28° at the front, not when air lifted. 28° angle is only possible with modified inner CV's (grinding the cups), Heri axles (they are crap!) or SVX axles which I actually run.
I could have full time 30cm front 35cm rear ground clearance without the piston air lift system by changing the lower spring perch to a higher position but it would stress the CV's and I would lose some compression because the springs would lock before I could use the maximum length of the strut shaft.
Comfort doesn't change much when the Forester is on "high" position, its slightly harsher because of the suspension geometry but hardly noticable.
