When is a Car "Level" - Home Front End Alignment

@72bluNblu is right on. I went to a local well know alignment shop who was recommended to me to have my falcon aligned. This was after I had installed a complete new tci front end with coil overs and adjustable everything, and 18x10s all around. He quoted me $400 and went to look up the specs. I said hell no and put my skosh chart and my money back in my pocket went home and bought some turning plates and a longacre gauge and have been doing my own alignments since.
