Just did a check on the superformance website, and they are showing the following dealers in the Northeast.

Here is my dealer for upstate NY,
Time Machines Motorsports LLC
Contact: Rick Muck
9820A Keller Road
Clarence Center, NY 14032
Tel: (716)-407-0975
Best I know, Snakepit is no longer an authorized SPF dealer. I have not talked to Bill at Snakepit in a long time. Hope all is well with him!
Time Machines is Rick Muck, who goes WAY back in the Cobra scene.
Maybe someone else can check in with more info.
hope this helps,
Jim
