I did 2.5" drop spindles and disk brakes up front and 3" drop springs in the back. I also did 20" wheels in the back and 18" in the front with tire sizes that do make for almost a 2" difference.
Mine is noticeably lowered and raked, but I generally don't have to worry about bumps and such on the road or uneven driveways. The only time I've ever had issues was out at my dad's farm on a very steep, rocky driveway. Bumped the lower control arms off a few rocks there.
