DIA is great I took my "06 Sequoia there exclusively until I left for Germany 3 years ago. Would definitely recommend.I’ve taken my FJ62 to DIA automotive and have had good luck with them, they tend to be slow at times but have come under new ownership and are getting better. If you go through DIA just be specific with what you want, i.e. if you want to keep it budget then let them know or if you want top of the line also let them know
If you have wiring issues the guys at SoundWave Customs do excellent work.
Are you opposed to doing the brake and suspension work yourself?
