That set up looks good. No the Bilstiens are separate. I replaced pretty much my entire front suspension. Strut wise I replaced, Struts, springs,mounts the entire pack. I also replaced stabilizer bushings and ends, inner and outer tie rods (if do again I would do entire steering rack and pinion comes with inner rods) upper control arms, lower A arm outer bushings, Wheel bearings, brakes rotors, brake lines. None of these seemed to be and issue but at 230k when I change felt it was time and figure since taking apart do it all.
Our vehicles are really capable off road but upgraded after market parts are hard to come by actually they do not make them. I ended up using Moog constant rate springs works well but if I were to redo I would go with variable rate springs.
The trimming is minor I got the best price from 4wheel parts and had them install since they do this all the time they hd the trimming tool again really minor trimming and its only plastic being the bumper cap part. Note: 4wheel parts sucks on service if you have one in your area so beyond installing tires they are a no go.
