Drift Rules


Tectaloy International Drift Challenge – Judging Criteria

Competitors will be judged on the following criteria:

The speed that the competitor maintains…
• entering a corner,
• through the corner,
• through the entire judged area.

A higher point score will be awarded to a competitor whose vehicle maintains a consistent, high-speed drift (relative to the radius of each corner).

How closely a competitor’s vehicle is able to follow the line requested by the Judges during the drivers’ briefing (usually this is the traditional ‘racing line’ but this is not always the case). A higher point score will be awarded to Competitors who can most accurately maintain what the Judges consider to be the correct line. There will be a combination of clipping points and clipping zones on the track, and Judges will be requesting drivers to be within a certain distance and anything outside of that will start to see deductions.

The angle of rotation of the vehicle about its vertical axis relative to its direction of travel, as well as the competitor’s ability to sustain this angle for as long as possible.

A higher point score will be awarded to Competitors who are able to:
• quickly generate maximum angle during entry into corners, from as great a distance possible prior to reaching the apex of the corner,
• link corners using a consistent series of drifting motions,
• maintain a wide angle of drift for sustained periods, and
• control the vehicle when maximum amount of opposite lock is used.

Style comprises the driver’s ability to take all of the judge’s criteria and then translate this into their own individual ‘style’ on track. It takes into account such factors as: fast and aggressive transitions; maintaining maximum angle for as prolonged period as possible along a clipping zone or past a clipping point; ability to transition the car around the section with limited handbrake corrections; prolonged proximity to the lead vehicle in a battle situation; maintaining constant speed throughout the section; and any other specific criteria outlined by judges during driver’s briefing.

Judged Area of Track
Competitors will start their run from Turn 5, with the judged area starting from the entry into Turn 6, then including Turns 7, 8, 9 and 10. The judged area will conclude at the end of turn 10 as competitors continue down the South Circuit towards Turn 11.


Cones will be used to designate the beginning and end of the judged area. In addition, cones may be placed inside the judged area by the Judges as an aid (to both Judges and Competitors) to ensure that Competitors are taking the correct Line specified by the Judges.

Judging Position
Judges will be in an elevated position, located on the outside of the track between Turns 7 and 10. This position allows the Judges to have the best view of the judged area.

Judging System – Qualifying
Each judge will assess the qualifying runs separately using the General Judging Criteria and score each run out of a total of 100.

Competitors will be given 2 qualifying runs, with their qualifying score being the highest score of these. In the event that two Competitors achieve the same final score for qualifying, a ‘count-back’ will take place, where the two Competitors’ second best results will determine their ranking for final battles. The count-back only compares the two Competitors involved, not all the other Competitors in the field.

A spin during a qualifying run will record a zero (0). If there are two or more Competitors with a final qualifying score of zero (0), the Judges will rank Competitors based on observations of the Competitors throughout the event prior to this point.

Additional Notes – Judging

A spin during a battle will record a 0 for that run, handing the opponent a 10-0 win.

Off Track
Points will be heavily deducted from competitors who fail to stay on the track during qualifying or battle runs. One wheel off track will result in a points deduction depending on severity/ distance off and two wheels off track will result in a score of 0.

Overtaking During Battle
The competitor in the chase car should only attempt to overtake the lead car during a battle if:
• the lead car spins or goes off the track
• the lead car stops drifting or goes off the Line far enough that the chase car can complete the manoeuvre without impeding, blocking or otherwise preventing the lead car from drifting effectively.
Please note that a competitor who can maintain close proximity without overtaking will generally be awarded more points than a competitor who chooses to overtake poorly.

Collisions during competition

For safety and financial reasons, collisions are to be actively avoided. If a collision is accidental and minor in nature, Judges may elect not to take the collision into consideration, particularly if the other Competitor involved is able to keep drifting. Judges will have the sole discretion for deciding which competitor is at fault and deducting points accordingly. If the collision is deemed to be serious by the officials, the determination of which driver is at fault will be at the sole discretion of the Clerk of Course. This relates to the application of the CAMS regulations and related penalties. In addition, Judges may use their discretion for applying penalties as they relate to the point score awarded for the battle.

Accident Avoidance
If the lead car makes a mistake (spins or straightens) and the chase car is forced to stop drifting or take evasive action to avoid a collision with the lead car, the lead car will be penalised for this with points deducted accordingly. In this circumstance, the chase car will not be penalised for having to stop drifting in order to avoid a collision. Judges will have the sole discretion for deciding which Competitor is at fault and deducting points accordingly.

Brake Checking or Baulking
If the lead car deliberately brakes or slows down during a battle in order to gain an unfair advantage over the chase car, the competitor will receive one warning from either the Clerk of Course or the Head Judge, and the battle will be re-run. If the competitor continues to brake or deliberately slow during any subsequent battles during the event, the Competitor may either be given zero (0) points for the run, or disqualified from the
event. Sole discretion for the administering of penalties shall rest with the Head Judge in this instance.

‘Drag Race Cones’
A pair of cones will be placed either side of the track at a distance from the start line to be determined by the Judges. In battles, it is the responsibility of the lead car to ensure that both cars remain side-by-side until this point. These cones are used so that Competitors in cars with less power are not unduly advantaged, and to encourage closer proximity between Competitors during battles. Should the Competitors’ vehicles not be considered side-by-side when they reach the cones, the run will be black-flagged and the Competitors will be sent around to start line again for a re-run of that single run (NOT the entire battle). The Competitor responsible will receive a total of 2 warnings for the entire event, and the third will result in disqualification.

Please note these warnings and penalties apply just as much to Competitors who deliberately accelerate too slowly as they do to competitors who accelerate away too quickly from the start line. Sole discretion for the administering of penalties shall rest with the Head Judge, in consultation with the flag marshal at turn 5, in this instance.

Unsporting Behaviour
If the Judges or Clerk of Course deem that a competitor demonstrates deliberate behaviour that gives an unreasonable competitive advantage, the Competitor may be penalised or disqualified from competition.

Feedback from Judges
Competitors may wish to request feedback from Judges to ascertain which areas they need to improve. This will only occur on an ad-hoc and informal basis and may only be requested by Competitors during practice sessions. Competitors are not permitted to enter the judging area at any time.

For qualifying runs and battles, a computer printout of results will be available before the battles begin (in the case of qualifying) or before the following round (during battles).

The Judges’ Decision is Final
As per the CAMS‐approved regulations, the Judges’ decision is final. Judging drift events is subjective. Therefore, Competitors are asked to respect the decisions of the Judges, even if they disagree with the outcome. Abuse or intimidation of judges will not be tolerated. Offenders may be referred to the CAMS stewards and/or be excluded from future events.

Five Minute Rule
If competitors experience issues with their vehicle during competition, they will be allowed five minutes to fix the issue without penalty. The countdown begins as soon as the vehicle stops in the pit and ends when the car returns to the start line.. Competitors will be advised appropriately by TIDC staff as to how long they have left. If the pit stop exceeds five minutes, the competitor will be disqualified.
