4.12     A scratch rated driver may have his skill factor altered by discretion of the Race Director.

 

Race Procedure

 

4.13     There will be no official free practice allowed on the Friday prior to the Race weekend. There will free practice on the Saturday (subject to local track operating hours) preceding Sundays racing and where possible, practice sessions will be organised on race day (Sunday) by the Race Director. The criteria for the duration and number of sessions being the engine start time, number of entrants and mix of skill factors. This under normal circumstances will be done in heat order at the discretion of the Race Director.

4.14     Group ‘C’ or Sports Car bodyshells can be used for racing as long as they appear in the BRCA approved list of bodyshells (see Appendix) and conform to their respective construction rules.

4.15     Four rounds of heats will be run if the total number of entries is 40 or less.

4.16     The appointed Race Director may not participate in the days racing. The Race Director will be in control of driving standards, interference decisions, protests, rule applications, etc. and will be appointed by the club in consultation with the BRCA.

4.17     All interference claims and any protests MUST be referred to the Race Director. Any subsequent action will be made by the Race Director whose decision will be final. Any driver claiming interference must switch off and see the Race Director WHILE THE RACE IS STILL IN PROGRESS. The following guide-lines will be used by Race Directors:- To ensure continuity no qualifying heat will be stopped unless the Race Director is satisfied that two or more drivers have detectable interference. The Race Director will aim to provide each competitor with ONE heat free from extraneous interference. The Race Director will check interference possibilities with all drivers before the start of finals and these races will not be stopped unless the Race Director is satisfied that on site interference is occurring. A driver claiming interference must switch off and report to the Race Director immediately. At the discretion of the Race Director any competitor found with equipment causing on site interference will be asked to leave the circuit.

4.18     The Race Director will also monitor driving standards and competitor behaviour. For a first offence the Race Director will normally impose a 10 second penalty off that heat (adjusted at the end of the heat). For a second offence, a one lap penalty, and for a third offence, disqualification from the meeting.

4.19     The Race Director may impose penalties without warning where he considers the infringement or misbehaviour to warrant such penalty. As a guide to drivers the following driving standards are expected:-Slower cars are to give way to the faster cars and the driver of the slower car should call his intention of moving off line. Deliberate collision from behind with an on line car at a corner (T-boning) will be regarded as an unacceptable practice.

4.20     Any driver not fulfilling his marshalling obligation will be penalised by loss of his/her FTD. Drivers MUST arrange a competent substitute if they are unable to marshal for any reason. Unless the Race Director considers special needs apply and except for the driver performing scrutineering duties, marshalling obligations will be as follows:- Drivers to marshal the heat following the one in which they race, except for drivers from the last heat who marshal heat one. Drivers from the Open Final will marshal the First Final to be run. Finalists four to ten will marshal the Final following the one for which they have qualified.

4.21     The Race Director may request inspection of any entrants car, at any time, to cover any or all applicable specifications. Any part of a car may be substituted during a race except the chassis. The chassis may be changed with the approval of the Race Director. The essence of this is that a car cannot be replaced or substituted once entered into a days racing.

4.22     Racing will commence at the start of the day, and no race, heat or race programme will be stopped, or delayed, due to reasons of change in the weather.

4.23     The pit lane must be kept clear at all times. Re-fuelling must take place clear of cars passing through the pit lane. Only one mechanic per driver to be allowed in the pit lane during the race.

4.24            Frequency pegs must be used during practice, heats and finals. Every driver must own a peg with his/her name on it which he/she will place on the pegboard in place of the frequency peg he/she is using.

 

5.  Scrutineering

5.2       The race director will use his discretion to select a suitable person from each heat to perform the scrutineering function. A committee member, will scrutineer first to fourth positions in each of the finals.

5.3       At the end of a heat all cars that have taken part in that heat must be taken together with the fuel bottle to the scrutineering area. Even if a car has been wrecked during the course of that heat it still must be presented to the scrutineer. Failure to do this will result in loss of FTD.
