Sounds like a very nice setup
The Koni's do a great job of balancing a daily driven ride and weekend "adventures"
They are one of the few struts that can handle slightly stiffer than stock springs to pretty damn stiff springs (I think some of the guys w/ GC coilvers are running 400#ish springs)
As you turn the knob towards full stiff you'll definitely get things "firmed up". For autox I like to run a little more damping in the rear vs front- 1/4 from full stiff in the rear and a 1/2 turn from full stiff in front. For the track I run 1/2 from full stiff f/r.
I'll bet the drop looks pretty good w/ the RCE plates and wagon pinks
