| UPDATE |
| BRCA 1/8th Scale Rules 2002 |
| Technical Specifications |
| A car must be a 1/8th scale character representation of a racing car within the given dimensions. The Race Director may disqualify any car that, in his opinion, would be a hazard to spectators or other cars. |
| Engines/Fuel |
| The engine displacement must be 3.5cc. |
| The maximum percentage of Nitro allowed in fuels is 25% by volume. Random samples will be taken. A testing unit will be available in Race Control for use by competitors, which will be the same one as used by the scrutineers. |
| All cars must have a de-clutching device and operating brakes capable of stopping the car and holding the car motionless with the engine running. |
| The fuel system capacity including fuel pipe and filter (if fitted in line) from the tank to the carburettor shall not exceed 125cc. |
| Weight |
| The minimum dry weight (dry car no fuel) of a car complete with tyres, body and clips is 2.5kg. |
| Wheels/Tyres |
| Maximum wheel rim diameter 54 mm |
| Minimum wheel rim diameter 44 mm |
| Maximum width of FRONT tyre is 36mm |
| Maximum width of REAR tyre is 64mm |
| Minimum diameter of FRONT tyre is 60mm |
| Minimum diameter of REAR tyre is 65mm |
| Tyres must be black in appearance, and may only comprise of a maximum of four rings of rubber for the REAR tyres and three rings maximum for the FRONT tyres. |
| Treatment of the tyres with additives is prohibited. |
| Axles, quick release mechanisms or any items shall not protrude beyond the wheel rim. |
| Bumpers |
| Front bumpers must be fitted to the car to the same design and material as fitted to a "standard" kit car. Front bumper maximum width is 267mm but may extend 7mm beyond the side of the body but not to exceed 267mm total width. The bumper must not extend beyond the body at the front edge of the car. |
| Exhausts |
| The engine must be fitted with an adequate exhaust-silencing device, which is contained in the current BRCA approved listing (This BRCA list is used for reference only and does not imply that any other BRCA rule maybe enforced). A current list is published in the appendix. Any additions or deletions to this list will be published in Circuit Chatter. |
| Exhaust outlets must face horizontally or below. No additional extensions to the exhaust outlets are allowed. Outlets should be of 15mm length and 8mm inside diameter hole. The silencer and manifold may not be modified in any way other than by its variable length created by the joiner between the manifold and pipe. |
| Air Filters |
| All cars must be fitted with a suitable approved noise reduction air filter at all times. In the case of wet weather, the Race Director will announce when the conditions are wet enough to allow the use of wet weather air filters or the drilling of a 3mm (max diameter) drainage hole in the base of the Ins Box type of air filter (which must be resealed totally in dry conditions). |
| Any driver found not to be using the correct air filter would lose their FTD. |
| Windows |
| All cars must have transparent windows if fitted. Side and/or rear windows, if any. Side windows maybe removed to assist cooling. |
| Bodyshells & Wings |
| No portion of chassis, wheels, tyres or any other item (excluding bumper) may extend beyond the body except to the rear. |
| When initially entered in a meeting the body must be neatly finished and complete. The body and chassis must be securely joined at all times when the car is racing. |
| Body shells may only be strengthened/supported with the addition of plastic, Lexan®, carbon fibre or similar non-metallic product. |
| Wing/piano wire must not be used for body support or strengthening. Wings should be mounted using manufacturers mounting points only. |
| Where a separate wing is used (applies to Sports Cars only ) and manufacturers wing mounts are not available, external/internal wing mount "wires" must be positioned along the body within the inside edge of the rear tyre and not further forward than the engine. |
| Group 'C' Cars |
| Only bodyshells from the approved BRCA 1/8th IC circuit list may be used. (See appendix for current list). |
| Any new body shell (i.e. not on the approved list) must be approved by the BRCA 1/8th circuit committee at least 1 month prior to the meeting at which it may be used. All bodyshells must be commercially available to all drivers. |
| Bumper width may extend 7mm beyond the side of the body, but must not exceed 267mm overall width. |
| Cut outs - A 10mm allowance is permissible around protrusions through the body shell (engine, roll over bar etc). Suitable apertures are allowed in the windscreen for engine cooling purposes. Fuel tank access - a 50mm diameter hole is allowed. |
| On Group C any part of the rear wing must not exceed 203mm height above the ground. |
| Side dams (if fitted) have to be part of the wing and must not exceed 80mm x 50mm. |
| No additional front wings may be fitted to a Group C bodyshell. |
| All other regulations covering tyres, body widths bumpers and apertures apply. |
| Sports Cars |

| Maximum size of rear wing side dams to be 80mm x 50mm |
| Maximum wing size 267mm width - 50mm chord - maximum angle to be 45 degrees. |
| Maximum rear wing height including side dams is 191mm. |
| In the case of the VDS Lola bodyshell no extra wings are allowed to be fitted but an external trim tab can be fitted to the rear of the body and it must not exceed 15 mm beyond the rear of the body. |
| 1/8th Open Meeting Procedure |
| 1. Safety And Hygiene |
| For BRCA recognition an Open meeting must meet such minimum safety and hygiene requirements as the Standards Sub-Committee decide appropriate for the venue and occasion, a minimum of which will be flushing toilets and running water. Details of the facilities offered to competitors must accompany details of race procedure and awards in all invitations for entry. |
| In order not to interfere with people's peace and quiet in the on site caravanning/camping facility, generators should not be run between the hours of 10-30pm and 9-00am. |
| Note: that any EFRA GP held in the UK be classified as a BRCA Open Meeting. (Invitation meetings may clash with Open meetings). |
| 2. Entry Procedure |
| (a) Details of meeting to be made available not less than four clear weeks before each meeting. Race entry fees to be £8.00 for all classes (£4 Juniors, OAPs, F.T. Students) £1.00 of which is payable to the Section Committee Fund. (Note. Does not apply at British Nationals). |
| (b) Pre-entry closing date to be no later than the Thursday preceding the race meeting. Entries being taken on a first-come basis. Entries received after this and before 8.30 a.m. on race day to be at an additional £5.00 premium with these entries in separate heats. No entries being accepted after 8.30 am on race day. |
| (c) No late entries and no substitute entries to be accepted. All entry fees pre-paid to be non-returnable except in exceptional circumstances by agreement with the BRCA. |
| (d) Any entry is a commitment to pay the set fee. Any unpaid moneys to be notified to the Sectional Committee who will not allow said drivers to compete further until moneys have been received. |
| (e) Where the entry is oversubscribed organisers will return entries after the maximum has been received. |
| (f) For British Nationals only - In order for a driver to qualify for the Open Final (in Group C or Sports Cars) at the National Championships Meeting, that driver must have competed in at least one BRCA 1/8th Open meeting in that class during the relevant season. |
| (g) Every driver entering a BRCA approved meeting should have proof of Association membership and carry their Membership Card, which should be produced upon request. Drivers must indicate their number on their entry form. Inclusion of a S.A.E. will give confirmation of entry. |
| (h) Radios should have at least two frequencies available and should be a legal frequency within the 40 MHZ FM or the 27 MHZ AM/FM band as specified by the Home Office and endorsed by the BRCA. Where frequencies conflict in the finals, the fastest qualifier shall choose, providing it is possible for drivers to change to the available frequencies. |
| (i) A scratch rated driver may have his skill factor altered by discretion of the Race Director. |
| 3. Race Procedure |
| (a) Four rounds of heats will be run if the total number of entries is 40 or less. |
| (b) 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. |
| (c) All interference claims and any protests MUST be referred to the Race Director. Any subsequent action will be agreed by the Race Director in consultation with the Referee. The decision of these officials shall be final. All direct approaches to the Race Director or Time Keeper will be ignored. |
| (d) 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:- |
| [i] To ensure continuity no qualifying heat will be stopped unless the Race Director is satisfied that two or more drivers have detectable interference. |
| [ii] The Race Director will aim to provide each competitor with ONE heat free from extraneous interference. |
| [iii] The Race Director will check interference possibilities with all drivers before the start of semi-finals and 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. |
| [iv] At the discretion of the Race Director any competitor found with equipment causing on site interference will be asked to leave the circuit. |
| (e) The Referee will also monitor driving standards and competitor behaviour. For a first offence the Race Director in consultation with the Referee 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. The Race Director may disqualify without warning where he considers the infringement or misbehaviour to warrant such penalty. Warnings are accumulative for each days racing. 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. |
| (f) Any driver not fulfilling his marshalling obligation will be penalised by loss of fastest time. Drivers MUST arrange a competent substitute if they are unable to marshal for any reason. Unless the Race Director considers special needs apply, marshalling obligations will be as follows: |
| [i] Drivers to marshal the heat following the one in which they race, except last heat drivers who marshal heat 1. |
| [ii] Drivers from the Open Final will marshal the First Final to be run. |
| [iii] All other finalists will marshal the Final following the one for which they have qualified. |
| (g) A Race Director or Referee may request inspection of any entrants car, at any time, to cover any or all applicable specifications. |
| (h) 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. |
| (j) The first day of an open meeting will be for Sports Cars, and the second day for Group C. |
| (k) The appointed Race Director may not participate in the days racing. |
| (l) 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. |
| (m) A Race Director may also act as a referee. |
| (o) 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 pitman per driver to be allowed in the pit lane during the race. |
| (p) Where possible (depending on rostrum facilities) a TRANSMITTER POUND will be in operation. Transmitters will be placed in the TX pound prior to the start of the first heat. The only time that a transmitter may be removed from the pound by someone not taking part in a final or heat is by permission of the Race Director (for servo adjusting, etc..) or if the driver has finished racing for the day and is leaving the track. |
| 4. Penalties |
| Any infringement of the rule regarding the quantity of Nitro percentage in fuel will be loss of his FTD up to that point in time. |
| Any infringement of the rule regarding the construction of tyres (no of rings etc) will result in the loss of his FTD up to that point in time. |
| Failure to marshal after your heat will result in loss of FTD up to that point in time. |
| Open finalists who fail to marshal the first final to be run will not take part in the Open Final. |
| Other finalists who fail to marshal the final following their final will have their result altered to 10th place in their final. |
| Failure to use a legal bodyshell will result in loss of FTD to that point in time. |

| 5. Practice |
| Practice sessions for each class and skill factor will be organised on the day by the Race Director.
