Rules will be simple (similar to the US Open Wheel rules):
Must have scale appearing cage, tail, hood, side panels, nerf bars, and bumpers.
Must run top wing - maximum wing surface area is 6" X 6" plus a 1/2" max rear spoiler, wing center section must be square. Left side panel max 4" x 7" max., right side panel 3.25" x 7". Front wing maximum surface area is 8 square inches with max side panels of 3" long and 1.5 " high, max of 1"above horizontal wing surface. Maximum front bumper width is 4". No lexan or any other material may be mounted to nerf bars or bumpers that may assist as an aero device.
Batteries: Any ROAR legal LiPo or 4600 mAh conventional 6-cell pack is legal.
Motors: Any ROAR stock 27t, Any fixed timing, tagged 19t, or any 17.5 or 13.5 brushless motor are all legal.
Tires: Foam tires only. No silicones. No truck foams.
these are the rules posted for the series....plus wide chassis cars are allowed,no weight limit ..trying to verify it but I do believe front wings are no longer allowed ..will update as soon as I hear from the boss :thumbsup:
