One thing you need to watch out for with this setup is when you have the struts almost fully extended (as they are even at rest) and you load them up in a turn, you put more stress on the strut and can break internal stuff. If the springs are soft enough to compress a whole bunch, that won't be much of an issue, I guess. I did see you lifting the inside front tire a lot, though - which is bad for acceleration.
The suspension I used today on the RS consists of springs from an 07 WRX (mine) and struts from a mad-tizzyte JDM Impreza STi Spec C. Lots of ground clearance, 3" of bump travel, 3.5" of droop, and the springs are soft enough to aborb the bumps while the struts are stiff enough to control the movement really well. Worked great. Had stiffer springs that were about 1/2" lower on it with the same struts before, and it bounced around too much on the slower stuff and would've bottomed out in a few places that this suspension just felt great on.
