4.2 MUD FLAPS, SILL AND UNDERBODY PROTECTION.
(a) Notwithstanding any Group or Category regulation providing specific requirements on the subject of coachwork and underbody protection, it is permitted to add material to the vehicle solely for protection from stone chip damage.
(b) Mud flaps of stout material shall be fitted behind all driving wheels, and in the case of front wheel drive vehicles, behind all four wheels. They shall be no closer than 50mm to, and no further than 100mm from,the ground, shall mask the full width of the tyre when viewed from behind, and be within 300mm of the tyre. Mud flaps fitted behind wheels shall leave un-masked at least one-third of the width of the car. Those fitted in front of the rear wheels shall leave at least 20cm un-masked. The vehicle shall comply with these requirements when it is presented in “ready to start” condition. Mud flaps may not be required for an Event only on Tarmac in which case the Event Supplementary Regulations shall detail the requirements. Mud flaps are not required in Tarmac Rallies.
(c) Where material is added to the sill and/or side of the vehicle it shall follow the contours of the existing body work.
Material is free with the following restrictions:
(i) pliable material maximum thickness of 6mm; e.g., polyurethane, rubber or similar;
(ii) solid material maximum thickness of 3mm; e.g., aluminium, Kevlar®/carbon/fibreglass.
(d) Where material is added to the underside of the vehicle sill it shall only be to the perimeter of the vehicle between the rear of the front arch and the front of the rear arch and shall be solely for the purpose of deflecting stones that may cause damage to the vehicle. The material must be pliable, e.g., polyurethane, rubber or similar, with a maximum thickness of 6mm and may not protrude further than the plan view of the vehicle or 100mm from the sill, whichever is the lesser.
(e) The fitment of underbody protection is permitted to protect the engine components (i.e. sump), transmission/gearbox components, final drive (differential) components and fuel tank components. The addition of this protection must not influence the aerodynamics of the Automobile. This underbody protection must not protrude beyond the original bodywork of the Automobile. Additional supports/mountings for underbody protection for these components are permitted provided their sole
purpose is to support these underbody protection elements. The material for underbody protection of these
components is free and may include composite materials.
(f) The fitment of underbody protection is permitted to the underside of the floor of an Automobile, provided that it is contained completely underneath the Automobile. This material must follow the general contours of the existing underside of the floor and may include chassis/monocoque rails. The material for underbody protection of these components is free and may include composite materials.
