JDPLOLZIN - I lowered my car almost 2 inches when I installed new lowering springs, ZQ8 Blazer brakes, shocks, tubular a-arms, sand blasted and repainted lower control arms and energy suspension bushings in the front. Full HR suspension and lowering springs went on the rear. The car sits great, handles very good and stops better than ever. The front-end alignment required a shim pack but worked out perfectly. I think the wheel/tire combination has to be figured into your plans to get the right stance you are looking for. I run rear GTA wheels on the front with 1" spacers and 245/50/16 Cooper Zeons. GTA fronts are on the back with a 1/4" spacer and BFG 255/50/16 drag radials. Handling is not as good of course when the drag radials are on but in full street trim I run 245/50/16 Cooper's on the rear.
PS - your upgrades sound great. I am only sharing what worked for me. I looked at Global's stuff and liked it but I am on the East coast and did not want to ship it from the West. I too weighed the options for lower control arms and could not justify the $400 min for a pair other than looking really cool. Good luck with your upgrades.
