The 2010 Rulles have been posted. They are located on the Driver Resources tab.
The USST National Series combines trucks from many different origins and blends them into a racing class that includes their different features. With the high expense of racing, fuel cost, and the economy in general, USST goal is for its racers to be able to use and depreciate the existing equipment they have invested in while moving toward a common truck. There is first goal of this rule set is to create a cornerstone on which to build equal competition between the following truck series; USST multiple divisions, I-70, Nashville, and ex-ARTS trucks.
90% of the trucks in these groups share three identical factors and one common factor:
- Perimeter frame
- Big Spring
- Steering Box (OEM style)
- Symmetrical Chassis
This most common style of truck in all the USST races is the baseline for 2009-2010. These four characteristics are the common denominators on which the USST National rule set is based.
The fundamental concept is that performance enhancing features are weighted depending on track size and banking. A table of equalization factors for different features on trucks is used to add or remove weight. This is a weight based rule set that is easily adjustable. Lead is the cheapest and most measurable equalizer. A baseline ruleset that new trucks will be constructed to will be released. Existing trucks follow the National rule set while USST moves towards the baseline rule set that new trucks will be constructed to.
There are 4 separate documents that describe the National Series rules for 2010.
- “USST National Performance Factors”: The definitions and listing of performance factors are described in this document.
- “USST National Series Procedures”: Describes race day activities and how each truck team will be given an assessment sheet to list these factors before events and their required weight will be calculated.
- “USST National Technical Rule Set”: Describes common rules that ALL teams will conform to. This describes the entire truck with the exception of engine and performance factors.
- “USST National Engine Rules Set”: Describes engines legal for National Series.
