In the high-adrenaline world of motorsports, every component of a vehicle not only needs to meet strict safety standards, but also contribute to overall performance. Door cards, often overlooked in everyday vehicles, are a critical aspect in racing cars for various reasons. This blog delves into why replacing standard door cards with specialised alternatives is a common and beneficial practice in the realm of motorsport.
Door cards, also known as door panels, are the interior sections of a vehicle’s doors. In standard cars, these panels are typically designed for aesthetics, comfort and functionality. They’re the part which has elements like armrests, window controls and storage compartments. However, in a racing car, these traditional door panels are less about luxury and more about performance and safety.
One of the primary reasons for replacing door cards in a racing vehicle is to reduce weight. Standard door panels can be quite heavy due to the materials used, such as plastics, fabrics and padding. In motorsports, every kilogram saved can contribute to a faster lap time. Racing door cards are often made from lightweight materials like carbon fibre and are stripped down to the bare essentials, eliminating unnecessary weight and thus enhancing the vehicle’s performance.
Safety is paramount in motorsports, and every element of a race car is designed with this in mind. Replacing standard door cards can also be a safety measure. In the event of an accident, traditional door panels can break into sharp, hazardous pieces, or their components (like speaker covers and pockets) can become projectiles. Racing door cards are typically simpler, with fewer components that could detach, reducing the risk of injury during a crash.
Motorsport governing bodies often have specific regulations regarding the construction and modification of race cars, including what is allowed inside the vehicle. Replacing door cards can be a compliance measure to meet these stringent standards, particularly in terms of fire resistance and emergency egress requirements.
Racing cars endure harsh conditions and require frequent maintenance and checks. Standard door cards have complex assemblies and materials that are not designed for quick repairs or replacements. Any damage to them can be costly and time consuming to repair. Racing door panels are designed to be robust and provide easy access to the inner workings of the door mechanisms for quick repairs, adjustments and inspections.
While performance and safety are the priorities, the aesthetic aspect of racing door panels can’t be ignored. They provide a clean, professional look consistent with the rest of the vehicle’s racing-specific modifications. Additionally, door cards in motorsports vehicles are often used as prime real estate for sponsorship logos and decals, contributing to the team’s branding and sponsorship strategies.
For rally cars and other motorsports vehicles where races might require additional navigation tools or communication equipment, custom door cards can be designed to accommodate these needs. This could include bespoke mounts for items like intercom systems, extra lighting switches, or map pockets, tailored specifically to the needs of the driver and co-driver.
Replacing door cards in a racing car or motorsport vehicle is more than just a cosmetic upgrade. It’s a strategic decision aimed at enhancing performance, safety and compliance. Whether by reducing weight, increasing safety, or complying with racing regulations, the customisation of door panels is a critical step in the meticulous preparation of a vehicle for the rigours of competitive racing.
