ALRC
Supplementary Competition Regulations. |

ALRC Rules & Regulations – Finalised Ratified Copy – 24.08.06 |
Background. |
| The
“ARC ...building for the future” policy document
was presented in September 1996 by the ARC Council. A key part of this
policy was that “The regulations will state any and all
variations permitted for all standard vehicle classes and modified vehicle
classes.” Subsequently, a request was put forward by the
ARC secretary at the EGM on Dec. 7th 1996 that the Scrutineering Committee
should revise the rules in order to show what changes to a vehicle are
permitted, rather than those that aren’t. Furthermore, taking a
lead from the wording of the Policy Document, ‘Special’ vehicles
would be known as ‘Modified’. |
To
set a starting point, we need to define a “Standard Vehicle”
and then list what alterations, additions, subtractions and component substitutions
may be made. It’s not hard to visualise a standard factory vehicle
as one which has a defined range of engine types and sizes, body style variations,
chassis shape and the transmission and suspension systems that go with them
- all using Land Rover components. This obviously includes a clearly defined
set of bought-in items. In other words, catalogued options / choices only.
The ALRC Vehicle Dimensions Chart (printed in the ALRC Handbook) lists engines
sizes and physical dimensions for most models. The vehicle should have the
suspension type as appropriate and ALL bodywork, windows, bumpers etc. as
appropriate for the model. Changes to gain competitive advantage will be
very limited on Standard Class vehicles but quite wide-ranging for Modified
vehicles.
That is our starting point. |
So
having defined a “Standard Vehicle”:-
A) The Standard Class regulations consist of practically no major “competitive
advantage” alterations but may define a wide range of minor ones and
some component substitutions or service replacement items.
B) The Modified Class regulations will list further alterations and component
substitutions that are allowed to a Standard Class vehicle.
|
These
rules have been written to accommodate all existing vehicles as far as possible
(as required by the Policy Document, which says “This policy
does not change in any way the eligibility of current vehicles nor will
it in the future.”) although some currently Standard Class
vehicles may need to be run in the Modified Class either permanently or
until modified to suit the Standard Class requirements.
Any rule clarifications previously established by the Scrutineering &
Off-Road Committee do not apply to this set of regulations.
|
The regulations
are divided into the following layout:-
Part 1 General Vehicle Regulations *
(Structure and equipment of all vehicles.)
Part 2 Event-Specific Vehicle Regulations *
(Structure and equipment of vehicles specific to defined events.)
Part 3 Competition Regulations **
(Describes the manner in which the vehicles compete in events, and the
organisation of those events.)
* (Subject
to the full rule change process) ** (May be changed by vote at an EGM
/ AGM)

Part
1 General Vehicle Regulations. |
| Section
A - General |
| A.1. |
As
a general principle in all vehicle regulations, it is prohibited to carry
out any tuning or modification that is not specifically permitted. The fact
that some modifications are mentioned as prohibited does not imply that
others are allowed. |
| A.2. |
Source
Rover Company to 2001.
Land Rover by whoever owned. |
| A.3. |
Design
The vehicle shall be of a Land Rover design. Many alterations to the original
vehicles are permitted in the following regulations. These shall be in the
spirit of the regulations as well as styles, physical dimension(s) etc.
Any standard Land Rover accessory parts may be fitted.
|
| A.3.1. |
.Those modifications
necessary to comply with safety regulations are authorised. |
| A.4. |
MSA Regulations:-
These rules are to be read in conjunction with the MSA Regulations to be
found in the current 2006 MSA Competitors’ Yearbook (known as the
“Blue Book”). References to the MSA regulations are included
where applicable and / or where more information would be helpful.
|
| A.5. |
Definitions:- |
| A.5.1. |
“Where
factory fitted” - This expression (or something akin to it) appears
in the following rules. Where a change is made by
Land Rover Ltd. during the life-span of a model design, then the applicability
of that change is retrospective. For example, disc
brakes have replaced drum brakes at the rear of Defenders, so disc brakes
are now permitted at the rear of Ninety’s and One
Ten’s regardless of age. The factory mentioned is a Land Rover factory
or a location specified by Land Rover for official accessories to be added.
|
| A.5.2. |
“Equivalent
cross references” - Rover parts may be replaced with parts made by
other manufacturers on condition they are of the same basic design and are
offered for sale as direct like-for-like replacements for those Rover parts. |
| |
|
| Section
B - Standard Class Vehicle Regulations |
This
section lists the permitted changes from the original standard production
/ factory design and dimensions of the whole vehicle and its component parts.
When optimising a road-legal vehicle for off-road use, owners may need to
take advice on the suitability of any alterations to establish that they
are not detrimental to safety for public road use, and that the terms of
the vehicle’s insurance are not contravened.

| B.11.2. |
Fuel tank location
/ design may be changed. If the fuel tank is moved, a separate metal cover
(vented at the bottom) must be fitted even if a truck cab is fitted.
The basic requirement is to prevent fuel leaking onto the driver / navigator
if the vehicle overturns. The design should be such that any fuel that has
leaked into the cover when the vehicle was inverted, will drain onto the
ground when the vehicle is righted. The cover must NOT be sealed at the
bottom or fumes will be trapped
|
| B.11.3. |
Where an alternative
fuel to petrol or diesel is used, the installation must conform to current
Road Vehicle Construction & Use Regulations. If it is LPG, then follow
the LPG Industry Technical Association Code of Practice No. 11 as a minimum
specification. The cylinder(s) and the pipework must be protected to at
least the same standard as the original fuel system equipment. If the tank
is installed inside the passenger compartment, the tank must have a cover
to protect it and its valves and pipework etc. from damage. Relevant test
certificate(s) must be retained for inspection. Any date markings on the
pipework must remain legible. |
| B.11.4. |
Fuel pumps
are free |
| B.12. |
BODYWORK &
CHASSIS. |
| B.12.1. |

Series I, II,
IIA and III vehicles may be fitted with Defender-style bonnets, grilles
and front panels. |
| B.12.2.2. |
Composite material
bonnets are allowed if they have been made from fire retardant materials |
| B.12.2.3. |
If the vehicle
has a permanently fitted windscreen, then the bonnet may have holes, louvers,
air-scoops etc. |
| B.12.3. |
The shortening
of a chassis is permitted providing the resulting wheelbase matches the
body being used. The ends of the chassis may be altered to accommodate the
requisite style of bumpers and / or cross-members.
For example, if a Range Rover chassis is shortened to go under a 90 style
body, the wheelbase must be the same measurement as in a 90 and body dimensions
and appearance must be exactly as in a 90. All welding on the chassis must
be of a high standard.
|
| B.12.4. |
Cross members
and outriggers may be replaced by section of equal or greater strength than
the original whilst retaining original minimum silhouette. |

bumpers, and bumpers associated with winch installations are permitted on
condition they are no smaller or weaker than the originals. See LogBook
article Dimensions Chart for bumper widths. |
| B.13.2. |
. On Land Rovers,
bumpers, mounting and rear cross-members must be straight, have at least
equal strength to the original fitment and shall be mounted in the original
position with the front and rear faces presenting flat vertical faces. |
| B.13.3. |
On Range Rover
/ Discovery / Freelander bumpers must be of original size and shape and
have at least equal strength to the
original fitment. Bumper sizes and shapes may vary with the model concerned.
|
| B.14. |
BATTERIES. |
| B.14.1. |
Non-standard
batteries are permitted but wet batteries must be fitted with anti-spillage
caps. All types of battery must be separated from the driver / passenger
compartment by means of a bulkhead or cover, must be securely fixed and
if moved from the normal place of fitment must be adequately covered to
contain any spillage in the event of a roll over. Covers do not have to
be of metal; plastic and wood are acceptable |
| B.15. |
BRAKES |
| B.15.1. |
The hand-brake
lever may be altered or changed in order to meet the requirement that the
hand brake is operable by the driver whilst wearing a seat belt. |

being started in gear. |
| B.19. |
RECOVERY POINTS. |
| B.19.1. |
Adequate front
and rear recovery attachments must be provided for recovery purposes in
all events. Bumpers, tie-down rings, lifting rings or Range Rover / Discovery
"tow fittings" are not adequate. Factory specification (or better)
trailer hitches are acceptable. If a tow-ball is fitted, welding alone is
insufficient - high tensile nuts and bolts must be used for attachment.
If the recovery point is attached to a bumper, the bumper must be attached
to the chassis with high tensile nuts and bolts. A clevis and pin fitting
or pair of Land Rover chassis-shackles (not spring shackles) are recommended. |
| B.20. |
NON-ROVER PARTS |
| B.20.1. |
