USAC/TORC SPORTSMAN and PRO BUGGY RULE UPDATES for 2010

Formula 4x4 and Classix: These classes will be combined into one class, ”Classix 2WD/4WD”. If the car count would increase there would be a possibility of splitting the class in 2011. In the interest of competition, rules may be changed at any time. Going into the future it is very important to cosmetically clean up some of these vehicles.

Enduro Truck: Cross over exhaust is not allowed. All trucks must use dual pipes with a 1 1/2 X 24 inch restrictor pipe. Exhaust must be welded together and well mounted to chassis. If the restrictor pipe is lost during competition penalties may be imposed. Aftermarket headers are not allowed. Anti-wrap up bars are not allowed.

1600 Buggy: With the single port engine a carburetor spacer (carb. to intake) of no more than 3/8 inch will be allowed.

Stock Truck: Any OEM steering box is allowed as long as the pitman arm location does not change significantly. The 15 year rule will no longer apply. OEM cab floor and firewall must match frame and be mounted in the stock location. Only very limited trimming of material will be allowed. The remainder of the OEM cab is not required. Updating of the body is allowed as long as the stock body lines are kept and it is done in a professional way. All trucks must have a radio and a spotter.

Limited 2WD: This class will continue in 2010 with no rule changes. All cars must have a radio and a spotter.

Limited 4x4 (Ultra 4x4): This will be a separate class in 2010. They will use the 2009 rules but now can use the Limited 2WD engine package and must be 10 pounds per cubic inch minimum. PRO 4WD trucks will be allowed to participate in this class. These trucks must use an open front diff. and be 10.5 pounds per cubic inch. They must also use the Limited 2WD engine package with an automatic transmission and DOT tires. Race numbers will be 400-499 series. In the interest of competition rules may be changed at any time. It is planned that this class will run at the same time as Limited 2WD. Car counts in 2010 will impact the future of this class. All trucks must have a radio and spotter.

PRO Super Buggy: Starting grids will use a 12 car inversion. All cars must have a radio and a spotter. No other rule changes for 2010.

General rule updates for all Sportsman classes: The competition yellow will be used with points awarded, two for first and one for second. ALL classes must have looped bumpers, body mounts and side bars. Only SFI 45.1 roll bar padding will be allowed. Mud flaps are required on all truck classes including Classix. They must be at least as wide as the tire, touch the ground and be made of semi ridged plastic, not rubber. The maximum exhaust decibel reading of 100 (50 feet from trackside) will be strictly enforced in all classes. Brake lights will no longer be required. Windshield screens will be required in all classes. The exact size and design is yet to be determined.
