1 Fastest piece of Real Estate in Tennessee 2018 Late Model Sportsman updated 3/14/18 The 2017 Season was a successful season for the LM Sportsman division as car counts and competition was strong all year. The 2018 LM Sportsman Season will be comprised of approx. (10-14) 50 lap Feature events plus the season shootout The Ridge Runner 100 as the final LMS event for 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.

2 These rules are meant to allow older fabricated perimeter chassis and the 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 2016 legal Sportsman cars lap times. This is an effort to keep the 2016 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 2016 Sportsman Cars In the event the ownership feel the rules are obviously allowing the fabricated chassis cars an 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 2016/17 Sportsman legal cars. Our total goal is to provide close competitive side by side racing throughout the field for our fans. 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.
