Your Tahoe looks great! It has IHO just the right height and stance. Which kit did you end up using?
I ordered the Belltech 1019 kit and used the 1 inch spacers that go under the rear springs. With the spacers the rear is supposed to be about 3 inches. The kit has what they call 2 inch drop spindles but I don't think it lowers the front a full 2 inches. It's more like 1 3/4 or there about.
I'm pretty happy wit it. The kit got rid of all the extra open fender well but didn't put it so low that I'm hitting on the speed bumps. Likewise, it didn't change any of the ride characteristics. It's still smooth and quiet as well.
