Alignment Shop in SoCal

We installed air ride triangular 4 link. Custom install. Works great but already ripped up the frame once and had to reiinforce. I drive it hard. This alignment guy is a hot rod guy and one man show. If you saw his shop you would know he is not in the business of ripping people off. Old school with no fancy equipment. He called me and said he was going to get the camber from -3 to -1/4. Everyone tells me -1 is the way to go on camber and +3 to +5 on caster. I have real tight clearance issues with the 18 inch wheels/2 inch drop spindels and will hope to get the -1 camber without problems.
