Extreme Supercars Regulations

National Challenge Series

Extreme Supercars is a category of circuit car racing conceived and promoted by Zwartkops. The aim is to provide a high end racing series for GT cars incorporating high performance saloon cars (mainly ex production cars) which is the main attraction for the spectators at the Extreme Festivals.

At present the overall championship is based on Time-Based classes but the longer term objective is to have a balance between Time-Based classes and Power-to-Weight homologated classes competing for the overall championship.


  • To provide racing that is rewarding for the competitor and sponsor, and exciting for the spectator.
  • To showcase modern cars and recognizable brands.
  • To each year declare a class winner for each class and an overall champion.

Eligibility of Competitor

Extreme Supercars is an invitation series where the Extreme Supercar committee (the committee) reserves the right to accept or decline any entry. All Competitors must hold any current circuit racing MSA license.

  • The committee will decide in which class/classes a competitor will compete
  • The committee shall have the right to change a competitor’s class in their sole discretion at any time
  • Class allocation will be done according to the guidelines set out below:

Time Based Classes (There are Six Classes) as follows:


Immediate Break time
Class A: GT cars only from 01:03.50 Class A: Zwartkops 1m 03.5 – 1m 04.5; Kyalami 1m 43.5 – 1m 46.0
To 01:04.49
Class B: GT cars only from 01:04.50 Class B: Zwartkops 1m 04.5 – 1m 06.0; Kyalami 1m 46.0 – 1m 49.0
To 01:05.99
*Class C: GT cars only from 01:06.00 Class C: Zwartkops 1m 06.0 – 1m 08.0; Kyalami 1m49.0 – 1m 52.0
To 01:07.99
*Class D: Production cars only from 01:06.00 Class D: Zwartkops 1m 06.0 – 1m 08.0; Kyalami 1m 49.0 – 1m 52.0
To 01:07.99
Class E: Production & GT cars from 01:08.00 Class E: Zwartkops 1m 08.0 – 1m10.0; Kyalami 1m 52.0 – 1m 55.0
To 01:11:99
Class F: Production & GT cars from 01:10.00 Class F: Zwartkops 1m 10.0 – 1m14.0; Kyalami 1m 55.0 – 2m 02.0
To 01:13:99

*If at an event there are less than 3 cars in the class it will be combined with another class for the day as follows: GT400 with Class B; and Class C with Class D. For both trophies and championship points.

A new competitor will be allocated to a time based class after race 1. This will be based on his/her best lap time in qualifying and race 1.

Only lap times achieved at Zwartkops and Kyalami will be taken into account for class determination.

What happens on breakout?

Once allocated to a class the competitor remains in that class unless he/she breaks out or applies to the committee to change class.

A class change to a higher class will be immediate upon breaking the lap time for the class for classes B- D. For example: if you are in class C and you record a time in qualifying, race1 or race2 faster than 1m8.0s you will automatically move up a class to class B and be scored as such for the day.

A Competitor may after the race meeting apply to the committee in writing, supported by good reason, to change from a higher class back to a lower class for the following event (ie from Class B to Class C). The same immediate breakout rule (4.4.5 above) will still apply.

Class A and Class D: If a competitor records a lap time faster than the laptime specified in point4.4.1 above in qualifying by more than 0.5sec or in race1 by 0.001sec a 5 place penalty will be imposed for the grid of the next race. If in race 2 a competitor breakout by more than 0.001sec on any lap they will receive a time penalty of at least 1sec per racing minute which will be added to the total race time.

Championship Scoring

Points will be scored for each race separately and for each class separately. The points awarded will vary according to the number of competitors per class, as follows: 3 competitors or more in class: 10 8 6 5 4 3 2 1 1or2 competitors in a class: 6 5

All other competitors classified as finishers in the results published by the organisers of the meeting get 1 point.

All non-finishers get 1 point. To qualify to score points you have to complete a lap in any official timed session of the race meeting (practice, warm up, qualifying or a lap in either race).

Class Changes

If a competitor changes class then based on the below table he/she will carry the specified percentage of points to the higher class.

Points percentage carried
At or before 4th Event 100%
5th Event 90%
6th Event 75%
7th Event 65%
8th Event or later 0%

Example: A competitor usually competes in class C but exceeds the maximum lap time at the fifth event which puts the them into class B. This competitor will carry 90% of his/her points into class B.

All races score points and count towards the overall championship.

Grids and Starts

Qualifying will determine the grid for race1. The finishing order of race1 will be the grid for race2.

A competitor who is competing in another category on the same day may elect to use the time set in that qualifying session for the Extreme Supercar Grid and not to set a time in the Extreme Supercar qualifying session. Unless adverse weather conditions dictate an unfair advantage.

All Starts are rolling starts.

No overtaking is allowed before the start line of the race.

Maintaining space at the start: At the start of the race no vehicle may be next to another vehicle as they cross the start line. In other words there must be a gap between the front bumper of one vehicle and the rear bumper of the vehicle starting in front of it. This will be monitored using the camera based timing system. Contravention of this rule will result in the offending competitor receiving a 15 sec jump start penalty added to their race time.


Although points will be scored on a per race basis, trophies are awarded on the combined race times of race 1 and race 2 (or race 3 in the event that there are three races on a day).


No Bumping Yellow Card System

Extreme Supercars is a NO BUMPING series and as such yellow cards will be given to competitors who contact other cars in any official timed session (race/Qualifying/warm up). Yellow cards will be given to competitors who are deemed, by the Extreme Supercar committee, guilty of unsporting behavior. Unsporting behavior includes contact between cars in a race. A competitor will receive one yellow card per incident and therefore may receive more than one card in any official timed session.

It is the duty of every competitor to report any contact with another competitor’s car to a committee member within 30 minutes after the end of a race.

The Committee reserves the right to investigate any incident and issue yellow cards at its discretion.

If a driver is contacted in front of the rear wheel, both drivers may receive a yellow card regardless of guilt.

If a car is contacted on or behind the rear wheel, the incident will be investigated and a yellow card might not be given; the discretion of the committee will be used.

If a competitor receives a yellow card he or she will be penalised as follows:

Yellow Card
1st yellow card: less 1 championship point
2nd yellow card: less an additional 2 championship points
3rd yellow card: less an additional 4 championship points
4th yellow card: less an additional 8 points championship points + possible suspension for the remainder of the championship

The committee decision is final.

Number of starters:

If there are less than 20 starters the committee may decide to combine the Extreme Supercar race with another category to increase the spectator appeal on the day.


For each event a competitor must use the same set of tyres in qualifying and the races. In the event of a puncture or major tyre destruction a competitor may apply in writing to the committee to replace 2 tyres.

Additions and Amendments:

Any provision unforeseen in drawing up these regulations and specifications, or any additions or amendments to be made thereto, shall be the subject of a circular to these rules, issued by the Extreme Supercar Committee.
