Final Version - of 15 – Issued 17/12/09

Places prior to issue of the first Grid Sheets for any round, the timesset in practice shall determine their grid positions. If Reserves aregiven places after publication of the grid sheet and prior to cars beingcollected in the Official “Assembly Area” they will be placed at therear of the grid and be started without any time delay. Otherwisethey will be held in the Pitlane and be released to start the race afterthe last car to start the Green Flag Lap or last car to take the starthas passed the startline or pitlane exit whichever is the later. Suchapproval to start MUST be obtained from the Clerk of Course.7. Acceptance of Entries: Up to Closing Day, Race meetingorganisers may accept up to the maximum number of starterspermitted on the Track Licence for the circuit (“the maximum”). If entries received by closing day exceed the maximum, selection willbe made in order of receipt. Those in excess of the maximum andup to 20% more will be treated as ‘reserves’. If the maximum hasnot been reached by closing day, entries received after that date willbe accepted strictly in order of receipt until the maximum is reached.

3.2: BRI EFINGS:Organisers must notify competitors of the times and locations for allbriefings in the Final Instructions or Official Race Day Bulletins for

the meetings. Competitors must attend all briefings.

3.3: PRACTICE:Practice sessions will be as per MSA Regulations Q4.5. Should anypractice session be disrupted, the Clerk of the Course shall not beobliged to resume the session or re-run sessions to achieve thechampionship criteria and the decision of the Clerk of the Courseshall be final.

3.4: QUALIFICATION:Each driver should complete a minimum of 3 laps practice in the carto be raced and in the correct session in order to qualify for selectionand order of precedence as set out in MSA regulations Q4.5. Atrace meetings where there are two races, drivers’ finishing positionsin the first race will be used to set the grid for the second race. For

that second race, the fastest eight will have their grid positionsreversed (e.g. the race winner will start in position 8, the secondplaced driver will start in position 7 and so on). Drivers practisingout-of-session or qualifying by virtue of having raced at the circuitwithin the previous 12 months will be placed at the back of the grid . The Clerk of the Course and/or Stewards of the Meeting shall havethe right to exclude any driver whose practice times or driving areconsidered to be unsatisfactory - as per MSA Regulation Q4.5.

3.5: RACES:The standard minimum scheduled race distance shall be 13 minutesplus 1 lap but should any race distance be reduced at the discretionof the Clerk of the Course or Stewards of the Meeting, it shall stillcount as a full points-scoring round.

3.6: STARTS:

Unless modified by the Organising Club’s Standing Regulations, thefollowing regulations shall apply:-1. There will be a minimum elapsed period of 3 minutes from carsbeing released from the Assembly Area to the start of the green flaglap.2. Start Procedure: A ‘two minute’ board will be shown on thestartline; engines should be started at this stage and the grid clearedof any pit crew. A ‘one minute’ board will be shown, followed by a ‘30 second’ board; a green flag will be waved from the start tocommence the green flag lap. The pole position driver should set areasonable pace during this lap and slow down on approaching thestartline to allow the grid to close up. Drivers should resume theircorrect grid positions with the minimum of delay. Any drivers unableto start the green flag lap or start the race are required to indicatetheir situation as per MSA regulation Q12.13.2. Drivers may make

up any lost grid position during this green flag lap, BUT any driversunable to maintain grid position to the extent that ALL other cars areahead of them, may complete the green flag lap but MUST remain atthe rear of the last row of the grid but ahead of any cars to bestarted with a time delay.3. A ‘5 second’ board will be displayed when the grid is stationary. Approximately 5 seconds after this board is withdrawn the red lights

will be switched on; after between 2 seconds and 7 seconds they willbe switched off to start the race. In the event of the failure of theselights a National Flag will be used to start the race. 4 . Any car removed from the grid or driven into the pits after leavingthe Assembly Area shall be held in the pitlane and may start the raceafter the last car to take the start from the grid has passed thestartline or pit exit lane whichever is the later.5 . Excessive weaving to warm-up tyres - using more than 50% of the track width - and falling back in order to accelerate and practicestarts, is prohibited.

3.7: RACE STOPS: As per Q5.4.3 of the current MSA Yearbook.

3.8: RE-SCRUTINY : All vehicles reported involved in contact incidents during races orpractice must be re-presented to the Scrutineers beforecontinuing in the races or practice.

3.9: PITS AND P ITLANE SAFETY :1 . Pits: Entrants must ensure that the MSA, Circuit Management and

Organising Club Safety Regulations are complied with at all times.2 . Pitlane: The outer lane or lanes are to be kept unobstructed toallow safe passage of cars at all times. The onus shall be on alldrivers to take all due care and drive at minimum speeds in pit lanes.3 . Refuelling may only be carried out in accordance with the MSA Regulation Q13, Circuit Management regulations and the SRs orFinal Instructions issued for each Circuit/Meeting.

3.10: RACE FINISHES: After taking the chequered flag drivers are required to: -Progressively and safely slow down, remain behind any competitorsahead of them, return to the pitlane entrance as instructed, complywith any directions given by Marshals or Officials and to keep theirhelmets on and harnesses done up while on the circuit or in thepitlane.

3.11: RESULTS: All Practice timesheets, grid sheets and Race Results are to bedeemed PROVISIONAL until all vehicles are released by Scrutineersafter post-practice/race scrutineering and/or after completion of any judicial or technical procedures.

3.12: TIMI NG MODULES:The 750 Motor Club utilises AMB transponder-based timing andcompetitors must have a compatible transponder fitted and advisethe race organisers of its number prior to the event. The transponderis a TRANX 260 Direct Powered and is available from HS Sports Ltd –01260 275708.

3.13: QUALIFICATION R ACES:If on closing date the number of entries received is at least 12 more

than the maximum number of starters permitted, the race meetingorganisers will endeavour to run two practice sessions and tworaces, divided by classes and/or known performance.

3.14: CANCELLED/A BANDONED RACES:There may be occasions when, due to circumstances on the day, ascheduled race is not run, a race meeting is abandoned or the circuitcurfew is reached. The 750 Motor Club will use its best endeavoursto find space in another race meeting in the same season in order torun a replacement championship round; preference will be given to arace meeting where the affected formula is already scheduled torace. No change of vehicle or class will be permitted without thepermission of the Championship Stewards and then only inexceptional circumstances.

A: The qualifying session for a race/ s does not take place. Entry for the replacement race will be restricted to those who were ‘signed on’ for the race which is being replaced. A separate qualifyingsession will normally be held. If no space can be found for areplacement race, the number of championship scoring rounds willbe adjusted accordingly.

8/3/2019 2010 Regs - F4




B: The qualifying session for a race/s ha s taken place, butthe race did not come under starters orders. Entry for the replacement race will be restricted to those who werequalified for the race which is being replaced; the grid for thecancelled race will be used for the replacement race. If no space canbe found for a replacement race, the number of championshipscoring rounds will be adjusted accordingly.

C: A race is ‘red flagged’ before the leader has completedtwo l aps, but there is no time available to restart the ra ce. Entry for the replacement race will be restricted to those who wouldhave been able to restart the race which is being replaced; the gridfor the cancelled race will be used for the replacement race. If nospace can be found for a replacement race, the number of championship scoring rounds will be adjusted accordingly.

D: A race is ‘red flagged’ after the leader has completed twolaps but less than 75% of its duration, but there is no timeavailable to implement MSA regulation Q5.4.2. If the Clerk of Course decides that a replacement race should be runit will be in accordance with MSA regulation Q5.4.2 . If no space

can be found for a replacement race, a result will be declaredretrospectively based on the order of crossing the finish line at onelap less than at the first time of the showing of the red flag and onlycars which were under their own power at the showing of the redflag will be classified.

If a race is ‘red flagged’ twice and the second red flag is beforethe leader has completed two laps, the Clerk of Course may decideto rerun the race on the same day subject to circuit curfew but is notobliged to do so. If the decision is taken that it should not be rerunon the day or it cannot because of circuit curfew, it will beconsidered an abandoned race and the number of championshipscoring rounds will be adjusted accordingly.

4: CHAMPI ONSHIP RACE PENALTIES:

4.1: INFR INGEMENT OF TECHNICAL REGULATIONS:1. Arising from post-practice scrutineering or judicial action: Should avehicle be found ineligible, the Clerk of Course will impose thepenalty set out in MSA Regulation C3.3. 2. Arising from post-race scrutineering or judicial action: Should avehicle be found ineligible, the Clerk of Course will impose thepenalties set out in MSA Regulation C3.5.1 a & b and may imposethe penalty set out in MSA Regulation C3.5.1 c. 3. Additional specific Championship penalties: See 4.2.2.

4.2: INFR INGEMENT OF NON-TECHNICAL MSA REGULATIONSand the Sporting Regulations issued for the Championship:1. In the case of a driver being excluded from a race, the Clerk of Course will impose the penalties set out in MSA Regulation C3.5.1 a& b and may impose the penalty set out in MSA Regulation C3.5.1 c.

2. In order to maintain standards of conduct, the ChampionshipOrganisers will monitor all Officials/Observers reports of adversebehaviour at race meetings. If any individual is included on two suchreports during one racing season the Championship Organisers willrequest the Clerk of Course at future race meetings to considerspecific observation of that driver’s conduct.3. The Clerk of Course may impose a ‘Stop-Go’ or ‘Drive through’ penalty during a race, in accordance with MSA Regulation Q12.6. 4. Any Competitor who is penalised under the ChampionshipSporting Regulations at any stage of a Championship event andreceives an allocation of penalty points on their race licence inaccordance with MSA regulations, will receive a grid slot penalty atthe next round in which they compete following the allocation of penalty points, equal to the number of penalty points which wereallocated. Double headers will be considered as two separate rounds;

however if the decision to allocate penalty points is delayed such thatfurther round/s of the Championship have taken place since theoffence, the grid slot penalty will be implemented at the next roundin which they compete after the allocation of the penalty points.The penalty will mean that a Competitor will be moved back grid slotplaces from their grid position (e.g. if a Competitor with a three gridslot penalty had a qualifying time that was good enough for pole

position then the Competitor will start fourth on the grid). If for anyreason the imposition of this grid penalty is impractical (such as thecompetitor’s qualifying time, starting from the pitlane etc) or theoffence occurs at the final meeting of the season, a time penalty of 5seconds will be added to the elapsed race time of the competitor.

providing the surface finish, which must remain standard, is notaffected. Forced induction is prohibited. Ram Air generated by theforward motion of the car is not considered as forced induction. Theexpression "Standard", "Standard production" or similar expression isdeemed to imply that the part has been manufactured by Ford, or aFord Motor Company Ltd. authorised sub contractor, for specific use ona specific model of the vehicle or engine. Consequently for these rulesonly parts manufactured specifically for the Ford 1800cc, 16 Valve

8/3/2019 2010 Regs - F4




engine (Zetec) in its 130PS form, may be used. Any machining markson cast components resulting from manufacturing procedures will notcause disqualification. Only machining and component preparationcarried out by Ford Motor Company Ltd., or by a Ford Motor CompanyLtd. authorised sub-contractor is allowed unless otherwise specified. Any production deburring or imperfection removal during initialmanufacture may not be modified or extended. The scrutineer’sdecision will be final (based on advice from Ford Manufacturing) if adispute arises regarding the amount of tool, or other marks that areevident in any particular component.The exterior surfaces only (of the complete engine assembly) of ferrousparts and the exterior surface of the aluminium cam cover may beprotected by paint or similar means. No internal component or surfacemay be coated by any protective finish. Other Ford produced aluminiumcomponents may be protected only on their external surfaces by atransparent clear varnish, or similar. No rework may be carried out onany component unless specifically authorised by the regulations. Theengine and associated parts must remain exactly as produced by theFord Motor Company unless expressly detailed in these regulations. If the regulation allows a change, then that authorisation would allow thechange to be carried out. However any statement defining minimum

weight or dimensions does not grant permission for rework to obtainthese minimum values, unless carried out in accordance with theseregulations. Only Ford standard parts (parts manufactured by Ford or aFord Motor Company authorised sub contractor) specifically for the1800cc, 130PS version of the Zetec engine can be used in this series.No treatment that alters in any way the surface finish, hardness, orother property of the original production component is allowed. Theonly exception to this is any deposit derived from the lubrication andcombustion processes naturally occurring during the running of theengine. Ford reserve the right to prohibit the use of specificcomponents introduced as Production changes, if in the opinion of theFord Motor Company Limited, they are deemed to have a performanceadvantage. If in doubt contact Ford Motorsport or the series scrutineer.PERMITTED ENGINE: The only permitted engine is the Ford 1800cc,16 Valve (Zetec) engine in its 130PS form (code RQC or RQB) with
