i know this is an older thread but i thought that this would be helpful to someone in the future..i did a write up over on GMFS about lowering kits. If you'd like, i'll copy it here and you guys can sticky it. Here's the part about the 2" drop in the front

For the front:
Depending on the cash that you have to spend, you have a couple options to lower the front. Most commonly for a 2" drop, drop coils are used. Over time these coils will settle approximately another 1/4"-1/2." Perfect alignment should still be able to be achieved. Ride will be considerably rougher.

Also, another option to use would be a McGaughy's 2" drop spindle. NOTE:McGaughy's makes two different spindles. There is a 16"+ spindle that will work on all wheels 16" and larger. However, these 16"+ spindles will decrease your turning radius. The better of the option would be to run their 17"+ spindles. These spindles can be used on all wheels 17" and larger. Also note, if you are running 17" wheels, you'll have to grind down the stud on your balljoint directly below the nut & cotter pin on it. Although this doesn't sound ideal, these spindles retain a factory-like ride and also keep the stock turning radius. Belltech also makes spindles. Their first design was junk from what I recall; however, they did revise the design and I believe the new design is a good design.

personally if it were me, i'd do the McGaughy's spindles IF you have 17"+ wheels. I have 4" DJM lower control arms and my buddy has 2" LCA's and neither of us have perfect alignment.
