It is to be noted that the Tri-City races are 1 day races, and in some cases there will be a combination of Tri-City cars, running for Tri-City points and Invitational points, as well as invitational cars running for Invitational points and pay-outs.

* All cars entered must comply with the below mentioned set of Core running rules, and bring a copy of their Club’s Rule Book as well.

* Any non-northern (the Tri-City Race Tracks) drivers and cars may purchase a Thunder Mountain Speedway Club Membership.  They must conform 100% to the TMS Street Stock Rules package and be open to a full technical inspection at each race.

* Tri-City Race Officials reserve the right to run qualifier races or B mains in cases of extremely large car counts.

* There will be a $50 dollar one time 2016 registration fee to compete in the series.  Once drivers have registered than they will be eligible for all championship points earned and pay-outs, no matter how many races they attend. This fee will help with costs of advertising and all other moneys will go directly back into the point’s fund.

* All cars will have to run a decal package and will be told where decals need to be placed.

            We extend deep appreciation to Kane and the team at FBB Chartered Professional Accountants LLP for their generous sponsorship over the past years and wish them well in all their future endeavors.  We welcome and graciously thank the NEW series sponsor, Zimmer Autogroup for their commitment  of $5000 and to Lordco for jumping on board with $3000 towards the year-end championship point’s fund.  Finish Line Racing Products is also returning again this season as an associate sponsor with a renewed commitment of $1500.  Bentley Motorsports will be sponsoring the Fast Time winners as well, kicking in $100 per race.  Each club has agreed to contribute $1450 towards the year end points fund, with an additional $100 each for trophies for the top 5 in points.  Drivers planning on competing in this series will be responsible for filling out a 2017 Tri-City Registration form at or before Race # 1 in Williams Lake.  Transponders and RACE-ceiver radios will be used at all 3 Races and can be rented or purchased from Lynn Dunford @ TMS. ALL moneys raised will go towards advertising and the year end points fund; financial records available upon request.
