AKRA will open its second Vega USA American Sprint Cup Series this April 21-23 at Carolina Motorsports Park with the running of the first-ever North / South Shootout presented by MGM Chassis.

Entries continue to come in for this event and AKRA will accept pre-entries through the Tuesday before the race, April 18. Officials are expecting the largest entry count in the short history of this series at Kershaw. To pre-enter, go to https://akrasprint.com/shop/kershaw-north-south-shootout-shop/.

Below is a handful of important bulletins to keep in mind if you’re planning on joining us for what should be the best weekend of AKRA sprint racing yet!

The event format  will be the same as last season’s. Friday is practice day with group practice beginning at 11am and running until 5pm. Both Saturday and Sunday will consist of two rounds of morning practice; a five-minute qualifying session, one round of heat races and a main event for each class.

Heat race starting lineups will be set from qualifying results. Feature race starting lineups will be set from heat race results.

Saturday and Sunday drivers meetings will commence at approx. 8am with practice starting shortly after the conclusion of each day’s drivers meeting.

The Vega FH (Blue) is the spec tire for all classes except TaG Junior, TaG Senior and TaG Masters. The TaG divisions have a limited open tire rule including the Vega XM, Vega FH, Bridgestone YLM, Bridgestone YLC, Mojo D2 MG Yellow and Hoosier R60A.

The Vega W5 is the spec rain tire. For TaG class rain tires, see https://akrasprint.com/classes/akra-american-sprint-cup/.

For all classes except the three TaG divisions, a new set of Vega FH tires is required Saturday morning during practice or qualifying. As karts exit the track during Saturday morning’s qualifying round, each kart’s tires will be stenciled. This set of tires will be required for the remainder of Saturday and Sunday’s racing program. I.E., the tires you qualify with Saturday are the tires you must run for the event.

For TaG classes, new tires are required Saturday morning and Sunday morning. Tires will be stenciled after qualifying each day, and those tires must be used throughout each day’s racing program. Tires must be the same brand and compound on all four corners of the kart. No mixing brands and/or compounds.

Vega tires will be for sale at the track via the TS Racing parts trailer.  To pre-purchase tires, go to TSRacing.com.

The Pro Gas Animal Cadet division will now utilize the green slide rather than the green restrictor plate.

The stock Briggs & Stratton B91 silencer is the only approved silencer is all AKRA Briggs classes. All Briggs entrants, including Pro Gas Animal, must be utilizing the stock B91 silencer or it will be subject to disqualification. If you have questions on this, contact Bill McCutcheon.

2-CYCLE ROOKIE Class Weights
AKRA has created the 2-Cycle Rookie class in 2017 with a goal of offering a competitive points class for young drivers age 7 to 10 that utilizes the most popular 2-cycle cadet-level engine packages – IAME Micro (Restricted) Swift, Yamaha KT100, Rotax MicroMax (EVO and non-EVO) and the Micro Rok.

Based on lap time research from CMP and other tracks, AKRA has determined a baseline weight rules package that officials will monitor and adjust accordingly beginning with Friday practice at CMP.

The baseline weight structure will be: Micro Rok: 245 lbs.; IAME Restricted Swift: 240 lbs.; Rotax (EVO and non-EVO): 230 lbs.; Yamaha: 225 lbs.

Officials reserve the right to adjust weights for each engine package throughout the North / South Shootout at Kershaw, and at each event throughout the 2017 season. The primary goal will always be to keep each engine application as close as possible in speed and lap times.
