I feel you, whenever i have modifications/maintenance done to my car i am weary of who/where i take my vehicle to. Check out the Yelp reviews on em, nothing but good feedback. I to can vouch for them, they know their stuff. Their shop cars (Civic Type R, Skyline GTR, Integra Type R, etc) are all built. And built properly. They will get you what you need and get done whats needed. Another shop i can recommend is Mach III, they also do grade A work.thanks, i'll give them a call, i'm just concerned since i've heard a lot of horror stories about shops that just install the LSD without measuring preload if its in spec and putting in the wrong shims or not putting in any at all.
