hey Thanh, if you haven't found a shop already I really really really X999 recommend Accurate Alignment
Address:
971 N Batavia St, Orange, CA 9286
Why? They specializes in doing alignment for race cars and especially lowered cars.......don't go to those asian alignment shops.........they will lie outta their asses to condemn your lowered car and offer ridiculous prices for camber kits........and they won't even correct your toe right (personal experience)
The prices are steep though.........$120 for alignment and $80 for camber kit installation per side............ however they are very professional and friendly with the service.....they allowed me to sit inside the car as they aligned it........they even asked me what degrees of camber I wanted......I told them about -.75 and they did just that...........its been 3 years since my alignment and I never had a problem with premature tire wear again
Most people on here get away without front camber kits by zeroing out the toe........but I haplessly spent money zeroing out the toe at those cheap alignment shops for $45 TWICE and obviously I know now that they didn't know what they were doing........................so I bought the front camber kit and went to Accurate Alignment for the ultimate fix and I got it..............so the lesson I learned is to find the right shop and people to do the job
