Questions


What is Eligibility and what is a Buff Form?

One of the aims of the VSCC is to promote amateur competition for its members using cars constructed either before 1931, or (in some certain cases) before 1961, or, with permission of the Committee, using a conglomeration of components from specified cars built before 1941.

Excluding tours, social events and entrants into the 'champagne class' on rallies, a VSCC member wishing to compete on a Club event will required to do so in an eligible car; additionally cars running in the Invited class at VSCC events do not normally need a VSCC Eligibility Document, although some other recognised form of identification may be required.

It should be stressed that eligibility for competitions is quite a different subject to whether a car is Vintage or Post Vintage Thoroughbred (PVT); this has nothing to do with the class of membership.

YOU ONLY NEED TO APPPLY FOR AN ELIGIBILITY DOCUMENT IF YOU WANT TO ENTER YOUR CAR INTO COMPETITIONS RUN BY THE CLUB

These VSCC eligibility rules are supplementary to the General and Technical Regulations of the Motor Sports Association.  In drafting the Eligibility Rules three principles have been borne in mind:-
  1. simplicity
  2. ease of comprehension and application
  3. encouragement of more original cars, for which purpose the systems of class prizes and points scoring for the annual awards will be altered as and when the Committee decides

There are three categories of classification for competing cars:-

  1. Standard (cars to the original specification)
  2. Modified (cars with minor modifications such as might have been made by a private owner in the appropriate period)
  3. Special (cars with major modifications or comprising components from a variety of eligible cars)

It is clear that unless the rules are implausibly legalistic there will be grey areas. A standing Sub¬-Committee meets to examine such areas. A car's category may be changed at this Sub-committee's discretion but appeal may always be made to the Club’s main Committee.

The following items are specifically banned unless of a type or material originally fitted to, or used in the car concerned:-
disc brakes; turbochargers; electronic ignition or other engine management systems; alternators; telescopic shock absorbers; toothed belts; modern, tuned length, exhaust systems; fuel injection and the use of modern materials such as titanium, carbon fibre or glass-reinforced plastic

The following items are permitted in all categories:-
thin wall bearings, modern oil filters and electromechanical fuel pumps. Modified cars and specials may, in addition, use oil coolers

Cloning, i.e. breaking up one car to make two or more cars is not approved and cars manufactured in this way are not acceptable. It is also not acceptable to turn a sports car into a fake Historic Racing Car or a saloon car into a sports or touring car.

VSCC eligible cars should also look correct for their respective period. Owners may be required to remove or conceal modern materials, fixings or accessories even where a competitive advantage is not obtained.

In applying the rules, cars constructed from a mixture of original and copy parts, providing that such cars fall within the groups described by the Club, are accepted by the Club subject to the Committee's approval. It should be borne in mind that the Club does not accept newly built cars unless they contain a reasonable proportion of original parts. Therefore, once a car has been constructed in this manner, any replacement of any major component by a newly made version must first have the Committee's approval. If the replacement is approved, then the change must be recorded in the VSCC's Eligibility Document.

Any person contemplating assembling a car from parts must notify the Committee of the VSCC before starting its construction and should provide a detailed description of its specification. Should the car vary from this specification, the Committee reserves the right to insist on a new application as if the car had not been constructed. It also reserves the right to exclude a car if the final product no longer conforms to the spirit or letter of these regulations. Both while the assembly is in progress and upon completion, the car must be readily available for inspection by any person(s) nominated by the Committee.

The issue of a VSCC Eligibility Passport ('Buff Form') for a car is for the VSCC's own regulatory purposes and does not confer on or constitute authenticity to any car, nor does it imply any historical provenance to a car. The VSCC's Eligibility Documents and Passports are not to be used for any trade or commercial purpose. All VSCC Eligibility Documents, past and present, lose all validity on the transfer of the ownership of the vehicle in question. All new owners must make their own applications for eligibility for the car, though earlier applications may be taken into consideration.

BUFF FORM APPLICATIONS
For anyone new to the VSCC Eligibility process, a Buff Form is a document issued by the Club’s Eligibility Sub-Committee classifying a member’s car as Standard, Modified or Special for the Club’s competitive events with regards to the originality/accuracy of its main components (engine, gearbox, wheels, chassis etc) ensuring the cars that can be seen in action at a VSCC event are as they were in their ‘heyday’.

To clarify matters for all parties, no car will be accepted for any VSCC event (excluding tours, social events and the ‘champagne class’ on rallies) unless it holds an up-to-date current Buff Form issued in the name of the current owner. Therefore, if you intend to enter a car that is new to the Club or that has previously held a Buff Form in another name and you have taken ownership, you will have to complete a new application. With regards to the latter scenario, we remind members that just because a car is sold stating that it has a Buff Form, there is no guarantee that another will be issued. All applications must be made with a full set photographs now required so that complete detail of the car can be considered in order to better judge the classification that will apply.

There is a continuous flow of applications for Buff Forms that have to be dealt with by the volunteers who patiently undertake this work every week. The number varies but typically we are receiving some 7 or 8 a week. Many are straightforward and can be dealt with quickly but in many cases research has to be carried out and if the individual considering the form is uncertain about anything then it is referred to the next Eligibility Sub-Committee meeting usually held once a month, and the decision made then. As a consequence forms can be delayed up to 7 or 8 weeks before getting back to the owner. We apologise for this but it must be appreciated that the whole Eligibility system is entirely dependent on the time given by volunteer members in their spare time so please be patient.

In the past the office have tried to be as accommodating as possible in accepting entries from cars without current buff forms on a “to be accepted “ basis. However this has resulted on occasions with ineligible cars competing at our events with the Eligibility Sub-Committee receiving criticism for allowing this. So in future unless a car has a current buff form issued in the name of the current owner it will not be accepted for competition in events where a Buff Form is required by the Supplementary Regulations.

Buff Forms Summary

  • Any car entering a VSCC competitive event must hold an up-to-date current Buff Form issued in the name of the current owner
  • To apply for a Buff Form, please contact the VSCC Office
  • All Buff Form applications must be submitted with a complete set of the required photos before they will be looked at. The photographs can be hard-copies and can be sent with the form or electronic copies emailed to alexandra.elliot@vscc.co.uk
  • If you wish to enter a car for a VSCC event and have not got a current Buff Form, ensure to submit your application in plenty of time before the event’s closing deadline to give the Eligibility Sub-Committee as much time as possible to process it (up to 8 weeks)
  • When making an application or undertaking a new project, please provide as much information as you can (history, component details, drawings, photos etc). This will only help the Eligibility Sub-Committee in dealing with your query

Whilst this may be seen as unnecessary bureaucracy, the Club’s Eligibility Rules are a vital part of VSCC competition and the Club’s heritage; we hope this clarification of the process will make things easier for everyone and allow us to continue to host the very best Pre-war motorsport events for our competitors and members.

ELIGIBILITY QUERIES (EMAIL ADDRESS)
The Eligibility Sub-Committee are all volunteers and, therefore, do not work at the Club Office during the week. All Eligibility queries regarding new ‘build’ projects, ongoing Buff Form applications etc can be directed to the dedicated Eligibility email address escom@vscc.co.uk.

The various members of the Eligibility Sub-Committee can all access this and can respond directly to any member’s queries by this means.

Please note any correspondence posted to the Club Office will still be forwarded to the Eligibility Sub-Committee as previously.

What Definitions are Used to Describe VSCC Eligible Cars?

·        Vintage - Built on or before 31 Dec 1930                                          
 
·        Post Vintage Thoroughbred (PVT) - Built on or before 31 Dec 1940 and approved by the Committee
 
·        Historic - Built on or before the 31 December 1960 and approved by the Committee
 
The date of a car shall be the date of the youngest original major component, namely Chassis, Engine, Gearbox, Front axle and Rear axle. Items of a later date may be substituted without altering the dating of the car if they are identical to those of the original specification.
 
Types of Car. Notwithstanding any definitions promulgated elsewhere by any body or organisation, the VSCC uses the following car type definitions:
 
·        Racing Car - Cars built for speed events, or sports cars running without the equipment required to qualify as sports cars.
 
·        Historic Racing Car - Cars built for the sole purpose of racing, raced in the specified period and approved by the Committee.
 
·        Sports Car - Open cars with road equipment to UK legal requirements. This to include wings, windscreen, full size battery, efficient silencer and working lights; these must include two headlamps of appropriate minimum dimensions (a single lamp may be accepted if originally fitted).  If originally fitted they must have starter and dynamo. They must have at least two seats and a working reverse gear.
 
·        Touring Car - Open cars accepted by the Committee as being touring cars.
 
·        Saloon Car - Closed cars including such vehicles as coupes, landaulets and cabriolets running with hood up.
 
·        Light Car - Standard small vintage cars of modest performance accepted by the Light Car and Edwardian section.
 
·        Three-Wheeler - Three wheeled cars, which have been approved by the Committee.
 
·        Historic Special - Historic pre-war specials which retain their original identity.  These will be dated according to their latest major modification.
 
·        Aero-car - Eligible cars using Aeroplane or Dirigible engines and approved by the Committee. The actual engine to be used must have been manufactured before 1 January 1931.
 
All cars used in road events must be fitted with wings.
 
Originality Definitions. Notwithstanding any definitions promulgated elsewhere by any body or organisation, the VSCC uses the following component originality definitions:
 
·        Original Specification – As catalogued by the manufacturer for the model in the year of manufacture.
 
·        Original Type - As catalogued by the manufacturer for the model in the period. (See "Period Definitions".)
 
·        Original Kind - e.g. Leaf, coil. Internal expanding, external contracting, etc.
 
·        Original Configuration - e.g. ½ elliptic, ¼ elliptic, transverse, etc. and, updraft, side-draft etc.
 
Exceptions may be made to any of these rules, subject to the Committee's approval, which will usually (but not automatically) be given on the following grounds:
 
·        Originality.
 
·        Legislative requirements.
 
·       Non-availability of spares.
 
·        Safety. This does not cover modifications designed to make a car "safe" when driven at uncharacteristic speeds.
 
·        The fact that such modifications can be shown to have been made on a significant number of that model of car in the period.
 
·        Use of different materials from the original may be accepted in specific instances, but this should not be accepted as carte blanche.  All alterations to materials must be by Committee approval.
 
Such exceptions must be approved by the Committee and given in writing. Such approval does NOT give a precedent for any other car.
 
Specialised guidelines are available from the Club office for some makes of car, e.g. Austin 7, BMW, Fiat Balilla.
 
It should be noted that cars prepared in accordance with the VSCC technical regulations may not necessarily be eligible to have a FIA Historic Technical Passport issued. For the FIA form to be issued, cars must comply with the regulations in appendix "K" of the FIA Yearbook of Automobile Sport.

Which Tyres Can I Use in Race and Speed Events?

APPROVED TYRES LIST FOR RACE AND SPEED EVENTS

Following questions from competitors about the relative hardness of tyres being used in competition, Committee decided that it needed to have an approved tyre list for Race and Speed events. The main reason behind the move was that the VSCC Eligibility Regulations listed a standard that was impossible to assess and therefore to enforce.
 
There was concern that the previous regulation allowed for (unspecified), modern (cross-ply) road tyres with compounds softer than the Dunlop 204 compound to be used in Race and Speed Competition.  At the April 2011 Committee Meeting it was agreed that the word "competition" should be removed from the wording in the rules so that it now states "no tyres to be used of a compound softer than Dunlop 204". This was notified to the membership on line and in the June and July Newsletters. It was to be immediately effective but it was also recognised that there was no way of knowing which tyres complied and which did not. Accordingly it was made clear to competitors that, though the rule had been changed enforcement would be effected by means of an approved tyre list rather than ‘on-the-ground’ testing.
 
All of the following brands are provisionally approved for the 2013 racing season:
 
Avon AM23
Avon GP (Competition)
Avon HM Tourist
Avon SM Mk 11
Avon Super Safety

In addition the Dunlop Sidecar Tyre used on many Austin 7 cars, although softer than all of the above, is given exemption status for Austin 7s and may be used in VSCC competition until such time as a suitable and compliant alternative is available at which time a period of grace be allowed to ‘use–up’ remaining tyre life on those in use.
 
If you are running tyres that are not on this list, you should ask for them to be considered so that they might be added. 

How is eligibility decided?

From its roots in 1934, the Vintage Sports-Car Club quickly found its feet in representing sports cars built to a quality defined by a period. The question of the age of eligible cars is one which proved to be pivotal to the continuing history of the Club. Initially it was intended that the five-year-old rule would be on a rolling date basis and that in, say, 1937 a 1932 car would be allowed to compete. However it did not take long for this to change. At the Annual General Meeting in January 1936 the Captain, Tim Carson proposed that “During 1936, driving membership of the Club should be limited to owners of cars manufactured prior to 31st Dec 1930”. He went on to suggest that unless the membership numbers declined, the limit should be kept at 31st Dec 1930. Press Secretary, Cecil Clutton, said that he favoured 1930 as the limit year because it marked a definite period in motor car manufacture and that from 1930 onwards a new type of [mass produced] sports-car had become popular, a type which was not particularly desired in the Club. One member complained that if the proposed alteration to the rules were carried, the cars in the Club would eventually become so old that they would disintegrate and that if a later date were not subsequently adopted the membership of the Club would decrease. Captain A W Phillips of the Royal Automobile Club, even then the rule makers of motor sport, was not present but was quoted as saying that he considered it absolutely essential for the well-being of the Club that the year of eligibility for driving membership should not be advanced. There was further debate around the subject before a vote was taken which resulted in 23 – 5 votes in favour of keeping the date at 31 December 1930 and thus establishing the identity a Vintage Car and of the Club as it was then and as it still exists today.
