1 Fastest piece of Real Estate in Tennessee 2016 Late Model Sportsman Revised 1/27/16 These rules are meant to allow older fabricated perimeter chassis and 2015 Sportsman Cars to compete together while creating a level playing field for the different type of vehicles represented here. The lap time bench mark for the new LATE MODEL SPORTSMAN class will be the 2015 legal Sportsman cars lap times. This is an effort to keep the 2015 Sportsman racers from having to change anything major on their cars to be competitive with the Tubular chassis cars. These rules are an attempt to combine fabricated Perimeter chassis cars with the HRS 2015 Sportsman Cars In the event the ownership feel the rules are obviously allowing the fabricated chassis cars a advantage changes in rules will be made. The goal is to have both type chassis cars winning races and running competitively. The bench mark lap times will be based off the 2015 Sportsman legal cars. HRS Officials retain the right to determine eligibility. NOTICE: All equipment is subject to the approval of HRS officials. No equipment will be considered as having been approved by reason of having passed through the inspection process unobserved. Any equipment which does not conform to specifications or tolerances contained in this rulebook or in the appropriate Manuals, will not be eligible for approval. HRS reserves the right to adjust the total weight and or adjust left side weight when deemed necessary for equal competition purposes. NOTE: All cars must comply with the rules set forth by the Highland Rim Speedway rule book and reference manuals used in the inspection process. All cars and car parts are subject to HRS technical inspection processes. HRS is not required to follow any other sanctioning bodies or manufacturers guide lines in its inspection process. This division being a new undertaking we will constantly be looking and evaluating different chassis combinations so to make this division an inclusive division for all perimeter chassis.

2 RULE BOOK DISCLAIMER The rules and/or regulations set forth herein are designed to provide for the orderly conduct of racing events and to establish minimum acceptable requirements for such events. These rules shall govern the condition of all events, and by participating in these events, all participants are deemed to have complied with these rules. NO EXPRESSED OR IMPLIED WARRANTY OF SAFETY SHALL RESULT FROM PUBLICATIONS OF OR COMPLIANCE WITH THESE RULES AND OR REGULATIONS. They are intended as a guide for the conduct of the sport and are in no way a guarantee against injury or death to a participant, spectator, or official. The race director shall be empowered to permit reasonable and appropriate deviation from any of the specifications herein or impose any further restrictions that in his/her opinion do not alter the minimum acceptable requirements. NO EXPRESSED OR IMPLIED WARRANTY OF SAFETY SHALL RESULT FROM SUCH ALTERCATION OF SPECIFICATIONS. Any interpretation or deviation of these rules is left to the discretion of the officials. Their decision is final. ENTERTAINMENT VALUE 2016 Tighter Field, More Passing, More Competition, More Winners Never forget we are in the entertainment business we just happen to be using race cars to entertain our fans. Being in the entertainment business and the average fan likes close wheel to wheel racing action no average fan comes to see one car run off with the race. We will use whatever means we feel is necessary to make this a fair playing field even down to using Restrictor plates Race Procedures for Race Winners. Each race the winner from the previous race will start behind all cars who qualify, as long as they make an attempt to qualify. If the winner from the previous week does not attempt to qualify, he will be placed at the rear of the field. Once a driver WINS 3 feature races in a single season they will start no better than 11th place or in front of the Previous race winner in all future races for the season. Once at least a second person has won 3 features all drivers having won 3 features or more will draw to see who starts in the 11 th, 12 th, 13 th positions for that night.
