A few weeks back I asked for some input on 20 inch wheels for my 79 GMC step side. I went with a 20X 8.5 wheel and 275-45-20 tires. Here is the truck so far. I removed the bed rails, wheel well moldings, bumper guards, and replaced the grill and headlight bezels. Now I am looking to lower it 2-3 inches in front and 4 inches in back. Any suggestions on what kit to use? I want to drive this a lot so I need a decent comfort level. This is a great site for info by the way.
