General:

It is the driver’s responsibility to ensure that his/her car conforms to all the rules and regulations contained herein. Even if you buy an existing GTi Challenge car from someone, don't just accept that everything is legal on the car.The GTi Challenge Committee, including the Technical Sub-Committee, is not responsible for ensuring the legality of any car regardless of any inspections or checks that they may perform.

Only modifications and allowances detailed herein are permitted.  All components not referred to or not specifically mentioned in these Regulations will remain completely standard to factory specifications.  In other words – if it does not clearly say that you can do it – assume that you cannot!! Ignorance of the regulations will not be accepted as an excuse. If there is any uncertainty as to the legality of the modification, it is the responsibility of the competitor to seek approval in writing from the GTi Challenge Committee BEFORE the modification is done. If a competitor’s car has increased or decreased in power, it is his/her responsibility to hand a new dyno sheet to the Challenge Committee before the next race.

No tyres, stickers, race number or merchandise will be given to a driver unless the money has been paid.

NB: Competitors are instructed to note GCR 226 regarding “Interpretation of Regs and Specs”

as per your 2010 MSA Handbook

All other regulations as per the 2010 MSA Handbook.

All novice drivers, to undergo driver’s instruction, before being allowed to race.

The Committee’s decision is final as to whether or not the driver is permitted to race.

1. Definition – GTi Challenge, A class of racing that complies with the following regulations.

2. Aim – To declare a GTi Challenge Champion

3. Controllers – GTi Challenge Committee, WPMC

4. Qualifications

• Drivers must be in possession of an MSA Club Circuit Racing License.
• Only drivers based in the Western Province are eligible to enter Challenge, other than drivers by special invite from the GTi Challenge Committee.
• All drivers are to be registered members of the Western Province Motor Club.

5. Championship Scoring

• Points will be awarded on 7-5-4-3-2-1 basis. 
• In order for any competitor to score full points, there must be at least 6 starters per class.

· Should a class have fewer than 6 starters, points will be awarded on a sliding scale ie five starters 5-4-3-2-1; four starters 4-3-2-1; three starters 3-2-1 etc.

Procedures

(i) Official entry forms to be submitted to WPMC by no later than close of business two weeks before race day. Any entry accepted after this date may be defined as a “Late Entry”.

(ii) A “starter” is defined as a competitor who has participated in the official qualifying session listed in the regulations for the event or in one of the two heats, with one officially recorded timed lap. (Cars excluded from the days racing, as per CGR183, due to technical infringements will be deemed NOT to be a starter.)

(iii) Should the race be red flagged:

-Refer SSR 43 (i) for race stopped after less than 2 laps

-Refer SSR 43 (ii) for more than 2 laps but less than 75% race distance

-Refer SSR 43 (iii) for more than 75% race distance completed

-Refer SSR 43 (iv) for no restart after Red flag

(iv)        There may be a qualifying session of at least 10-15 mins, in order to determine your starting position for the two races.  You will need to complete at least 2 official timed laps.  Your fastest time will determine your starting grid position for Race 1, with your second fastest time determining your grid position for Race 2. 

(v)         Cars that complete no laps during qualifying for any reason shall start both heats behind the last qualifying car in the same class sorted by championship order, number of races completed or car number, whichever is first applicable.

Cars that complete only 1 qualifying lap shall start the second heat behind the last qualifying car in the same class sorted by championship order, number of races completed or car number, whichever is first applicable.

(vi) All cars have to enter the pit road via the weigh bridge after any officially timed session. Failure to do so will result in driver being excluded from that session. Any exclusion from qualifying, for any reason, shall be the same as if the car completed no timed laps. Rule v) to apply.

(vii)       If for whatever reason, the Stewards of the Meeting/Clerk Of The Course (COC), determine that no timed qualification session is possible:

• The grid for race 1 will be determined by each driver's quickest lap time during the last race meeting that they had entered at the circuit in question during the current season, including qualifying lap times
• The grid for race 1 will be sorted by class (i.e. all class A cars, followed by all class B cars, followed by all class C cars)
• Second heat grid to be determined by the finishing order of first heat.
• For race 1, entries received after the close of business on the Tuesday before the race day will start at the back of the class but in front of new drivers.
• For race 1, new drivers will be moved to back of grid in class order. A new driver is defined as any driver who has completed less than 4 heats.
• For the first race of the year the grid will be determined by the championship positions from the previous year in class order (i.e. all class A cars, followed by all class B cars, followed by all class C cars). If a driver has changed class from the previous year, the starting position will be from the back of the class.

(viii) Drivers must complete at least 75% of the full race distance in order to qualify for position points.  Both races will count for points, with Trophies being awarded for Overall positions for the two races combined.

(ix)       There will be approx 10 Rounds consisting of 2 heats each subject to the official calendar published by WPMC. Away races will count for points as well.

(x) Class points may not be transferred from one class to another. The Champion will be the competitor with the highest number of points scored overall at the end of the racing season, irrespective of class.

(xi)       Should 2 or more drivers end on the same points – Refer GCR229.

6. Bonus Points:  Bonus points will be awarded for the following:

(i)        Race Appearance – 1 point per race meeting (Driver must complete at least 1 officially timed lap)

** Lap Records will be reset:

• each year
• if technical engine/gearbox/tyres rules change
• weight divisions change
• if there are changes to the Killarney Race Track.

 (v)        GTi Challenge Meetings – 1 point per meeting.

            All drivers who are in possession of a GTi Challenge race number and are paid up members of the GTi Club are deemed to be competing in the series and are required to attend all meetings called by the GTi Challenge Committee (whether they competed in the last race or not).

(b.8) All drivers will purchase the compulsory bracket for weight penalties, as supplied by the Challenge Committee and must be secured in the front passenger seat area with the weight secured to the bracket.

* Specifications for new model cars will be accommodated as they are built ie  New Beetle, Golf 4 and 5 as well as New Polo (Hatch and Classic)

Y.   Protests / Technical Checks:

- All cars will be run on the GTi Challenge designated dyno before they are allowed to race.  The dyno owner, committee and car owner will be given copies of the results.  In order to protest a car/driver, a fellow competitor must fill in a “Protest Form” within  ½ hour of the 2^nd Heat of the day.  These forms will be available at the CoC office.

- The protest is to be specific ie Motor, Power, Gearbox, Suspension or Brakes, Bodywork etc.

- The Car(s) in question will have their bonnets locked and will be locked away in a designated area at the race track. 

- Checks will be done at an agreed venue and time. Should the car(s) be illegal and the fault be seen as an unfair advantage, the GTi Challenge Committee will exclude the driver(s) from the results for the day and no points will be awarded. If the car is found to be illegal after qualifying or 1st heat, it will not be allowed to continue racing on the day. Fuel may not be added, so drivers are required to finish a race with at least 5 Litres of fuel left in the tank. Cars may only be transported by trailer to the GTi Challenge designated dyno for checking unless otherwise agreed by the Technical Sub-Committee. The car(s) will be given 2 runs, with the average taken between the two.  Cars will be allowed a 3% tolerance (Kilowatts and Torque on the flywheel) on the applicable maximum Class (power & torque) to weight figures. If the car is over by more than 3%, he/she will be excluded from the results for that day’s races.

Technical Checks:

For Technical Checks by the GTi Challenge Technical Committee, the same procedure will be followed.  If the checks are too difficult to be done at the track, the cars will be locked away and an agreed time will be arranged.  For power checks, all drivers will meet at an agreed time.

   i) The GTi Challenge Technical Committee reserves the right to request that any car, at random be checked.

   ii) The Technical Committee reserves the right to mark and seal the motor, as well as ECU’s and On Board ports (for laptop interfaces).

   iii) Should any of these seals/markings be tampered with, the driver will be excluded from the day’s results.

   iv) If there is any uncertainty as to the legality of potential modifications affecting these markings/seals, it is the responsibility of the competitor to seek approval in writing from the Technical Committee.

   v) Failure to do so, will result in exclusion, should these markings /seals be inspected (see i above)

Z.   Ceramic coating:

ONLY exhaust manifolds may be ceramic coated.
