I wanted to chime in here and add some feedback.
I recently purchased and installed non-reservoir Fox 2.5 extended travel front coilovers and rear Fox 2.0's mated with icon 2 inch springs. Also put in some SPC Upper Control arms.
This was the first suspension install I've ever done. I watched a bunch of YouTube videos and read every guide I could get my hands on and managed to feel comfortable enough to attempt the install. I paid attention, made sure I had all the right tools, and got to putting everything in over the span of 1.5 days.
My initial impression is that I absolutely love the ride. It's definitely stiffer than stock (but what isn't?) but not harsh by any means. It simply soaks up big bumps in a way I've never felt before. It doesn't wallow or heave over them like it used to. It just swallows them up, settles back down quickly, and maintains it's composure. Also body lean and brake dive are reduced big time, as would be expected.
I made sure to follow any info I could find about installing the sway bar relocation brackets and the radiator support spacers. Put everything in and I'm happy to report I have zero rubbing or any other fitment issues. I also made sure that the spacers on the front coilovers were facing forward. I was fortunate in that I didn't need to adjust the height on the front coilovers. The stock hight they came at, I think 2.25 iches of lift, was perfect for my needs. Still a little bit of front rake but less than stock.
I hate to hear that others have had issues with their setup, but I'm happy to report that my suspension feels dialed in and we'll matched. As of right now I'm incredibly happy with it. Granted, I've only had it put together for a week, so only time will tell how everything holds up.
While I'm sure King makes an amazing shock, and the ability to customize valving is interesting, for my needs I knew it'd be overkill. Plus, I managed to piece together and install my entire kit for $1,850 including all shipping costs. I could just barely get a set of front king coilovers for that much, let alone an entire suspension setup.
