WINGS (Direct from World of Outlaws)
Top Wing Option #1: (optional for 2008, mandatory in 2009)
a) Center Foil maximum size of 25 square feet with a maximum width of 60 inches. Center Foil must be square or rectangular in shape with all 4 corners set at 90° angles with no variance allowed. Center foil top is to be flat from front to back and side to side.
b) Center Foil shall be fully sheathed in aluminum. Vent holes, dimples, ridges, etc. are strictly prohibited anywhere on the wing.
c) Maximum 1” removable wicker bill may be mounted on the rear edge of the center foil. Wicker bill must be 90 degrees to the top of the center foil. No built-in wicker bills or gurney lips allowed. Maximum dimension of wicker bill may change periodically.
d) The top wing can be cockpit/driver adjustable. Other than the slider mechanism, no moving parts permitted on or in foil structure. Only one slider mechanism allowed on top wing, allowing adjustment forward and backwards only.
e) Center foil thickness cannot exceed 9 inches. Underneath side of center foil must appear to be a continuous smooth arc with no recesses, concaves, or protrusions. Center Foil must be one-piece construction. No split or bi-wings will be permitted. Wings must be fabricated of metal alloys only. No fiberglass, carbon fiber or other similar material may be used in the basic framework of the wings. Top wing must not extend beyond outside of rear tires.
f) No foils or rudders will be permitted anywhere on the top wing.

Top Wing Option #2: (optional for 2008, not allowed in 2009)
a) Center Foil maximum size of 25 square feet with a maximum width of 60 inches. Center Foil must be square or rectangular in shape with all 4 corners set at 90 degree angles with no variance allowed.
b) Center Foil shall be fully sheathed in aluminum. Vent holes, dimples, ridges, etc. are strictly prohibited anywhere on the wing.
c) No wicker bills or Gurney lips permitted on Center Foil.
d) The top wing can be cockpit/driver adjustable. Other than the slider mechanism, no moving parts permitted on or in foil structure. Only one slider mechanism allowed on top wing, allowing forward and backwards movement only.
e) The 12 inch section located at the rear of the Center Foil must not have the belly/curl arc out of proportion with the rest of the Center Foil. The belly/curl arc must span the entire length of the Center Foil and appear to be a gradual arc with the deepest point no further back than 48 inches from the leading edge. As measured on a 12 inch straight edge, the belly at 6 inches from the rear of the Foil may not be deeper than ½ inch. There is zero tolerance on this ½ inch depth. It is suggested that the wing blue print specify 15/32 inch depth, so that if any deflection or movement of the wing occurs, the depth will not exceed the ½ inch specification. (This ½ inch measurement ensures that the belly/curl arc is gradual.)
f) The belly/curl arc must start at the radius of the Center Foil’s leading edge and shall not exceed a depth of 2½ inches. Center Foil thickness cannot exceed 9 inches. Center Foil top surface from side to side must remain flat. Center Foil must be one-piece construction. No split or bi-wings will be permitted. Wings must be fabricated of metal alloys only. No fiberglass, carbon fiber or other similar material may be used in the basic framework of the wings. Top wing must not extend beyond outside of rear tires.

Front Wing:
a) Center Foil maximum size of 6 square feet with a maximum width of 36 inches. Center Foil must be square or rectangular in shape with all four corners set at 90° angles.
b) Center Foil shall be fully sheathed in aluminum. Vent holes, dimples, ridges, etc. are strictly prohibited anywhere on the wing.
c) No wicker bills or Gurney lips permitted on Center Foil unless the car is outfitted with Wing Option #1, in which case a maximum 1” removable wicker bill may be mounted on the rear edge of the center foil. Wicker bill must be 90 degrees to the top of the center foil. No built-in wicker bills or gurney lips allowed. Maximum dimension of wicker bill may change periodically.
d) Maximum distance from the Center Foil front edge to the front edge of the front axle may not exceed 20 inches.
e) The Center Foil front edge must remain at least 1 inch behind the front edge of the front bumper. Center Foil top surface from side to side must remain flat.
f) Center Foil must be one piece. No split or bi-wings will be permitted.
g) Wings must be fabricated of metal alloys only. No fiberglass, carbon fiber or other similar material may be used in the basic framework of the wings.
h) The Front Wing must not extend beyond outside of front tires. The Front Wing may not be cockpit or driver adjustable while the car is stationary or in motion.
i) No moving parts permitted on or in foil structure. No rudders or fins allowed.
j) The 5” section located at the rear of the front foil must not have a belly/curl arc that is out of proportion with the rest of the front foil. As measured on a 5-inch straight edge, the belly at 2 ½ inches from the rear of the foil may not be deeper than 3/8 inch. There is zero tolerance on this 3/8 inch depth. It is suggested that the wing blue print specify 11/32 inch depth, so that if any deflection or movement of the wing occurs, the depth will not exceed the 3/8 inch specification (This 3/8 inch measurement ensures that the belly/curl arc is gradual).
k) The belly/curl arc must span the entire length of the front foil and appear to be a gradual arc with the deepest point, no further back than 12 inches from the leading edge. The belly/curl arc must start at the front foil’s leading edge and shall not exceed a depth of 2 inches. Front foil thickness cannot exceed 3.6 inches.

DRIVER’S EQUIPMENT: The driver’s suit should be of multi-layered Nomex. Nomex underwear, socks and head sock are suggested. Driving gloves and racing shoes are strongly suggested. No alterations. USRA reserves the right to inspect any helmet for cracks or structural damage and reject same if necessary. CAR’S EQUIPMENT: Use a securely fastened steering wheel with a quick disconnect and removable steering wheel. No Aluminum roll cages, front axles, frames, rear bumpers or nerf bars. All roll cages must be higher than the driver’s helmet. Opening on left hand side of cockpit must be a minimum of (14) inches. No pop rivets or cotter keys to be used to fasten wings, bumpers or nerf bars to race car. You can not race without a hood. If you lose a rear bumper you may continue the race unless the car is stopped. If a red occurs you must replace the bumper in the allotted time before you can restart. A triangular safety net is suggested on the right side of the roll cage. Metal fasteners are strongly suggested. Left side net is suggested. ROCK SCREEN: Required. If a competitor does not have a rock screen, he must have one installed before the next night. MISCELLANEOUS: The following is highly regarded as very important to safety precautions. Please use a neck collar. Knee pads or other devices to keep the knees from banging around on objects causing injuries are encouraged. Shoulder/helmet restraints are also encouraged. A padded head rest and roll cage padding around the cranial area is an important item. A type of Styrofoam or fiberglass insulation of (1) inch thick with an upholstery type covering is suggested.
