For any of you racers that live in the DE, PA, NJ, or MD area. We have a great cup racer program at the Mushroom Bowl in Kennet Square, PA.
As of now we only run the cars stock with the exception of the threaded shocks, sway bars and tire additive.
Electronics wise any esc, battery and servo goes. We have handout motors dyno'd within 100 or 200 rpm's of each other.
But if you guys can round up 4 people you can run your own open Cup Class.
