Speed of Sound isn't my #1 choice for speed shops.
i have an import and i don't even go there.
maybe try 2xtreme on industrial blvd. in South Park. it's more of an import speed shop but the people there are a little nicer and then there's McB's in Bridgeville which i take my car to. Mark (the owner) is a really cool guy and knows his stuff. (he's a mechanic also)
McB's
548 Baldwin St
Bridgeville, PA 15017
412-221-1922
maybe give him a call. he's deals mostly with imports but could probably help you with what you need to know.
