"There's another member here who just opened a specialty shop, I'll have to go digging into the posts to find them."
This may be Dempsey Anderson (Oricale) at Evolution Motorsports Engineering (
http://www.evolution-motorsport.com/) in Northern Virginia. This is the newest shop that I'm aware of that has in-depth knowledge of ZR-1s. He does great work for a fair price, is meticulous with the details, treats your car like it's his own, and is well-known member to many on the forums.
