Thanks for the replies so far everyone.
I am resistent to Koni yellows due to their high cost, $800 for shocks and struts is too much for me and I'm not interested in adjustability. $360 for STR.T shocks and struts seems much more reasonable, as does the $420 for Steeda units.
I was always a little bummed by the ride height of my Steeda springs on my 07 GT, the car seemed a bit too tall. I know that's looks and not function, but it is part of the reason I was looking at Eibach. I want the suspension lowered, so not buying springs is not an option.
I enjoyed the Steeda video (I've seen it before), the concern I have with the Stage 2 is the cost as the kit has components I'm not sure I need (does the stock Ford strut tower brace not work well on our cars?) while missing parts I want (strut mounts & PHB). To go buy those parts separate would cost $220 more. If the stage 2 suspension from Steeda didn't come with the strut tower brace (assuming the stock one works fine) that $180 savings would almost make up for the additional parts cost.
My BIGGEST concern is purchasing stocks/struts that aren't matched to the springs. I'm concerned that buying Koni or Steeda stocks/struts and Eibach springs isn't the smart approach since they weren't designed to work together. I've owned Bilstein shocks/struts with H&R springs and it took buying two different sets of springs and mis-matching them to get my 92 LX to feel right...I don't want to go through that again.
I'm still undecided on my approach, but my new 19" black SVE Drift wheels showed up yesterday which means I need to get cracking on a suspension solution.
What I'm hearing so far is:
Eibach springs are OK, as are their anti-roll bars, but the shocks/struts are suspect.
Koni makes great stuff.
Upper and Lower rear control arms are something I might want to consider.
Steeda makes good stuff.
