I got my alignment done by Aligntechs in San Jose. I went with them because they are familiar with SPC products. They got my rig aligned to the best it could with the spc arms and my 33' tires. I couldn't be more pleased with my numbers. They are more expensive but I wanted to make sure i took it to a shop that was familiar with these uca's. I always bring the SPC alignment sheet for reference, but they dont ever need it. These guys are always busy, so make an appointment. I can show you my numbers for reference if you want, just PM me.
