I'm sure this has been asked a ton of times but i don't know that much about cars but do know what I want it to look like. I have a 07 trailblazer lt with 60k on it 4x4 and 20's with 265-50-20 I want to drop it down a 1 and a half or so. I know or at least think its hard to lower a 4x4?? so do you know a good kit that's affordable not crazy high priced and a site to find it out. And i will be having it installed by a mechanic thanks so much for any help.
