GTR in Rancho Cucamonga is really good and honest...it's a mustang shop by the way...tell em Mario with the black 94 convertible sent you and they will give you a hell of a deal since my girlfriend models for them.
No personal dealings with them, but my friend hates them, he got his whole suspension done there and it's been a nightmare. All he had done was suspension work. This is no way a flame on them, just a friends dealings.
I personally use Automotion in huntington beach, and get my tuning done at powertrain dynamics directly across the street from the other.
