Originating in Japan, Time Attacks have quickly been accelerated to the fastest growing form of non contact automotive racing. And now Rally Sport Direct is proud to present Lap Battle Time Attack Series at Miller Motorsports Park, bringing it to you like no one else! Our goal is to give racers and tuners the opportunity to showcase their talents on an actual race track. Behind the wheel of their own purpose built high performance race cars, without the danger associated with full door to door racing. To win Lap Battle a competitor will need to possess not only superior driving technique but in depth automotive tuning and development skill.

The Lap Battle ruleset and vehicle classing structure was created with one simple concept in mind... The fastest lap time wins! There wont be trophies for second place. There will be no runners up, so choose your equipment wisely. Lap Battle will consist of three distinct classes, Front Wheel Drive, Rear Wheel Drive and All Wheel Drive. For those competitors needing track compatible timing equipment, AMB Transponders will be available for rent from MMP for $25 a day. Timing will be required during Sunday Lap Battle event.

During Official Lap Battle events, each competitor will receive two(2) fully timed 20 minute practice/qualifying sessions. Then, the competitors will be split up into two groups determined by their earlier lap times. Each group will be given a single session to blast away the competition with their fastest lap times of the day. The quickest competitors in each of the three classes will win cash and prizes, while the fastest of those will go home with even more money and the title of Lap Battle Champion.

Official Lap Battle Rules

INTENT:

The goal of the Lap Battle Time Attack Series is to bridge the gap between entry level driving events and competitive road racing. While giving spectators, enthusiasts, competitors and sponsors a positive and visible forum to promote their activities and businesses. In an effort to help local competitors continue on to national level time attack events, Lap Battle is using a revised version of the Redline Time Attack rules. Please visit redlinetimeattack.com to review the official rules before attending an actual Redline event. 

GENERAL INFORMATION:

All cars need to be in top mechanical condition, it is the competitor's responsibility to inspect, prepare and maintain their own cars.

Lap Battle Time Attacks will consist of morning driver's meeting, two morning practice sessions an afternoon qualification session and a final Lap Battle session. Driver's missing the morning driver's meeting will be disqualified. During the qualifying session the top 3 finishing drivers in each class will move on to the Lap Battle Session. Each competitor will be timed via a track compatible transponder. The final Lap Battle sessions will provide the official Lap Battle Time Attack lap time results.

Automobile racing is an inherently dangerous sport.  Each Competitor assumes that risk when he or she participates in an Event.  The risk of serious injury of death cannot be eliminated and, in fact, will always be present at a high level.  Entrants are required to advise their spouses and next of kin, if any, of this fact.  Although safety generally is everyone’s concern, Miller Motorsports Park & Lap Battle cannot be and is not responsible for all or even most aspects of the safety effort.  That responsibility instead rests with the various participants in each Event. Lap Battle is a TIMED COMPETITION,  therefor no passengers of any kind will be allowed. Also, we highly suggest you carefully read through your auto insurance policy to verify event coverage. Lap Battle accepts no responsibility for any injury/death or damaged/lost/stolen property.

All persons driving in Lap Battle competitions must be at least 18 years of age and posses a valid Drivers License. Any vehicle or driver found to be unsafe by Lap Battle officials will be disqualified.

Flags: 

Green Flag: Start of race, track is clear, cancellation of a previous flag condition. 

Red Flag: The race is stopped.  It will be displayed only at the start/finish flag position.  In the event a red flag is displayed, a stationary black flag will also be displayed at each flagging station simultaneously with the red flag at the start/finish position.  All drivers must reduce speed and be prepared to stop at any time.  No passing is allowed.  All drivers must proceed in single file order back to the pit lane (not your pit spot) and wait further instructions from Lap Battle Officials in the pits.  Competitors may not perform any type of service on their race car until the event is restarted.  The red flag is also used in the pit lane to control exiting from the pit lane area. 

Yellow Flag: If the yellow flag is displayed in a motionless manner, it means danger, no passing, be prepared to slow down, course workers may be adjacent to the course.  If the yellow flag is waved, it means extreme danger, no passing, be prepared to slow down, course workers are on the course.  In either case, Competitors must be prepared to stop or take avoiding action. 

Double Yellows All Stations: Means full course yellow, danger, be prepared to slow down, no passing, course workers may be on the course, and the safety car will be on the course.  Competitors must be prepared to stop or take avoiding action. 

White Flag: If the white flag is displayed in a motionless manner, it means a slow moving race car, service vehicle, tow truck, ambulance or fire truck is ahead.  If the white flag is waved and displayed at start/finish line only, it means the start of the last lap.  When used at start/finish to signify the last lap, the white flag will be displayed to the leader first and then to the remainder of the Competitors. 

Yellow Flag with Red Stripes: Slippery surface or debris on the racing surface ahead. 

Blue Flag (or Blue Flag with Orange Diagonal): If the blue flag is displayed to a Competitor in a motionless manner, it means another Competitor is following or catching the flagged Competitor and may be trying to pass.  If the blue flag is waved, the Competitor to whom it is displayed must give way to the Competitor trying to pass.  The blue flag is ordinarily used for a Competitor who is unaware of an oveLap Battleking Competitor or is clearly obstructing another Competitor. 

Black Flag: If the black flag is displayed to a Competitor in a furled manner, it means the Competitor has committed an act of unsportsmanlike conduct.  The Competitor must discontinue the unsportsmanlike conduct or be penalized.  If the black flag is waved at a Competitor, the Competitor must stop in his or her pit on the next pass by the pit area for consultation with a Lap Battle Official.  It means that the Competitor has committed an infraction of the Rule Book or an act of unsportsmanlike conduct.  The Race Director may halt the timing and scoring of a Competitor who fails to obey a waving black flag after three consecutive laps.  Lap Battle may substitute the waved black flag or black flag with orange disc at start/finish line with an official directive to the team in pit lane to call the car in by radio. The Race Director may halt the scoring of the car following three crossings of the start/finish line following the official directive. 

Black Flag with Orange Disc: The Competitor’s car has a mechanical problem.  When this flag is displayed to a Competitor, they must report to their pit on the next lap. 

Black and White Checkered Flag: End of race or session.  All Competitors may take a cool off lap at reduced speeds or immediately return to the pit lane. 

Black Flag All: When the black flag is displayed to all Competitors, from the Start/finish line and all corner stations it means there is an interruption of practice or qualifying.  All Competitors on the course must return to the pits immediately, and my expect the practice or qualifying session to resume when the temporary situation giving rise to the black flag is corrected. 

Competitors not obeying standard flag protocol will be disqualified.

Class Structure: 

Street Class: Street Class will consist of 3 sub classes,  AWD,  RWD and FWD.

Race Class: Race Class will also consist of 3 sub classes,  AWD,  RWD and FWD.

Timing:

Protest Procedure:

Any competitor has the right to Protest another competitor on the grounds that their vehicle does not meet the rules. The Protest must be issued by another registered competitor,  not a Team Owner,  crew member,  family member,  etc. Upon receiving the Protest,  Lap Battle will conduct a Protest Inspection of the vehicle to determine if the vehicle meets the rules. If the vehicle in question DOES NOT meet the rules,  the vehicle’s lap times will be considered invalid,  the vehicle’s results will be removed from the official competition records. Decisions made by Lap Battle are final,  there will be no appeals.
