Clarifications for Road-going Series Production Cars

Classes SA, SB & SC
These classes are intended for near-standard cars with very few modifications (as listed), to encourage low-cost entry into the sport. All cars running in the above classes must remain in totally road legal form at all times.
All cars must have current VED & insurance in the name of the main driver, with a current MOT if age requires it.

Note. Trade plates and traders or company group insurance policies will not be accepted.

NO modifications (optional or otherwise) are permitted which are likely to improve the performance and handling of the car with the following exceptions:

Wheels & Tyres; The standard wheel rim width may be increased by a maximum of one inch and fitted with tyres to suit. Tyres must be from MSA list 1A and be Road Legal

Engine, Induction & Exhaust; The air cleaner and exhaust system must remain as production or OEM pattern replacement including catalyst if fitted. Electronic ignition may be fitted.

Suspension & Steering: The steering wheel may be replaced by a non-standard item. Uprated dampers may be fitted.

Brakes; An alternative or OEM pattern replacement brake friction material can be fitted, but modifications to the brake disc, caliper, drum or shoe are not permitted.

Body; In the interests of safety front seats may be replaced by competition versions which must be fully trimmed, not a bare shell. Loose over-mats may be removed but the original carpets, fixed floor mats, and floor trim, etc, must remain and in their original locations. Pyrotechnic safety devices such as airbags and seatbelt pretensioners may be disconnected or removed.

General; The spare wheel and any mounting or cover which is not permanently fixed to the body may be removed.

No other modifications, except the fitting of a roll cage, are allowed in classes SA, SB and SC.

Kit cars, limited production cars, space framed or non-ferrous chassis construction road cars and one-off road-going cars are not permitted in Classes SA, SB and SC.

In the event of an unresolved eligibility issue, the driver of the car concerned may be required to produce within four weeks of the event in question, a manufacturer’s catalogue to substantiate any queried modifications / specifications and allow championship points to stand.

Any modifications not specifically permitted are, by definition, not allowed.

Classes 1A to 1E

Tyres: must be from MSA list 1A and be Road Legal.

Exhaust systems; must include a working catalytic converter on all cars manufactured after 31st December 1999.

Engine & Gearbox; The engine block &/or cylinder head must remain as that fitted to the original model in both type and material. Internal modifications are allowed but the cubic capacity of the engine must remain within the same capacity class as the original car. Gearbox and differential casing must be of the original type and material and remain in the original position. Internal modifications are allowed

Brakes; Brake calipers, discs, master cylinder & pads can be modified. Carbon discs are not permitted. Modification of the brake pedal is permitted. Brake bias adjustment is allowed. The fitting of aftermarket pedal assemblies is not permitted.

Anti-Lock braking systems can be removed but cannot be added to a vehicle that does not have one as a manufacturer specified option.

CMC/LAC Three Sisters Sprint Regulation August 2011

Barbon 18th June 2011 Regulations

From:
(All classes) Towing eyes of adequate strength and size must be fitted to the front and rear of the vehicle. They must be painted a distinctive and contrasting colour. Cars of periods A to F and single seater racing cars are exempt from this requirement subject to a suitable towing point being clearly identified.

To:
(All classes) The vehicle must have a clearly identifiable towing point of adequate strength and size at both front & rear. A suitable point on the roll hoop will generally suffice for open single seat racing cars.

The MSA has suggested that we adopt the amended wording immediately, to make it easier for competitors to comply with the requirement of towing points.

This seems to be a sensible change that still requires the competitor to mark a suitable point on the car to attach a tow rope, in advance, and not to start thinking about it when the recovery crew are on their hands & knees in the grass at the side of the track!
It is likely that this wording, or something very similar, will be incorporated in the Blue Book effective from the 01/01/2013.

Following recent discussion regarding tyres in Roadgoing Categories for Sprint & Hill Climb Events, the Motor Sports Association is pleased to clarify the regulation as follows:

Tyre Requirements in Sprints & Hill Climbs

The Technical Regulations applicable to the Category of “Roadgoing Production Cars and Roadgoing Specialist Production Cars” are set out within (S)11.

(S)11.6.2. states:  Wheels and Tyres.  “Except for Period Defined Vehicles (Non-Rally) A-H inclusive are to (L) List 1A and List 1B.”

Championship/Event Organisers are then free, within these Categories, by means of Class Regulation to specify tyre choice to being either (L) List 1A, (L) List 1B or any specific tyre from either list.  In order to do so appropriate regulation must be incorporated into the specific Championship/Event Regulations.
