What should I remove?

Weight reduction is a precise art that involves removing unnecessary parts to make cars lighter and more efficient. Even small reductions can result in noticeable improvements in performance. Items without significant performance benefits or that duplicate functionality should be among the first to consider removing in a weight reduction strategy.

Sprung vs unsprung weight reduction

Sprung

The sprung weight includes all components of a vehicle supported by the suspension, like the chassis and body. Reducing sprung weight benefits overall vehicle performance, including acceleration, braking, and fuel efficiency. Targeting areas like the interior and non-essential components can bring down the sprung weight.

Unsprung

Unsprung weight affects parts not supported by the suspension, such as wheels, tires, and brakes. Lowering unsprung weight improves handling and ride quality, as the suspension system can adjust more dynamically to surface changes. It’s often more beneficial, albeit harder and costlier, to reduce unsprung weight for handling improvements.

Which one has more impact?

While reducing both sprung and unsprung weight offers performance perks, unsprung weight reduction usually has a more pronounced impact on handling. Decreasing these masses allows for quicker tire response to road conditions, thus enhancing traction and ride comfort.

Interior

Seats

Replacing factory seats with lighter, performance-focused alternatives can significantly cut weight. Racing seats and materials like carbon fiber offer strength without the added weight of cushy luxury seats. Appropriate support and restraint should never be compromised in pursuit of weight reduction, even with more minimalist options.

Boot Spares

Spare tires and tools stored in the boot contribute to vehicle weight. Some drivers opt to remove them to lighten the load, relying instead on fix-it-flat solutions or roadside assistance in emergencies. However, this should be weighed against safety considerations and the need for roadside repairs.

Extra interior parts

Interior elements like sound deadening materials, carpets, and console trim can be heavier than they seem. Replacing heavier materials with lightweight alternatives, or eliminating non-essential components, can offer meaningful reductions in weight while customizing the car’s aesthetics to align with performance needs.

Carbon Fibre And Fibreglass panels

Using carbon fiber and fiberglass panels in place of standard metal ones offers a substantial weight reduction, enhancing aerodynamics and overall performance. These materials are light and sturdy, providing a high strength-to-weight ratio, though they often come at a higher cost and may require professional fitting.

Polycarbonate windows

What is polycarbonate?

Polycarbonate is a durable plastic known for its resilience and transparency, making it an excellent alternative to regular glass for window applications. By replacing glass with polycarbonate, cars can see notable weight savings and increased resilience to impacts, further enhancing safety and performance characteristics.

Suspension And Wheels

Coilovers

Coilover suspension systems, which combine springs and dampers into a single unit, offer weight and tuning advantages over traditional suspension components. They allow for a lower center of gravity, improving handling and cornering performance while enabling tailored adjustments to suit driving conditions and preferences.

Arms and bushes

Lightweight control arms and solid bushes are essential for reducing unsprung weight. Upgrades in these areas can contribute positively to wheel alignment and steering responsiveness. Enhancements should aim for durability while reducing inefficient masses that hamper dynamic performance.

Brakes

Brake elements, like calipers and discs, can be optimized using lightweight material replacements, which improve deceleration times and handling by reducing unsprung weight. Performance-grade brake elements are standard in vehicles seeking aggressive performance increases.

Less fuel and body weight

Reducing fuel tank size or regularly maintaining a lower fuel level can offer minor weight savings. However, while this tactic contributes to overall weight reduction, it necessitates more frequent refueling and may not be practical for all driving scenarios.

Lightweight wheels

Switching to lightweight wheels improves acceleration, braking, and steering dynamics due to reduced unsprung weight. Alloys and carbon fiber options present excellent choices, enhancing both performance and visual aspects of a vehicle.

Exhaust system

Materials

Replacing the stock exhaust system with a lighter alternative made from materials like titanium or stainless steel can reduce weight significantly. These materials not only cut weight but also enhance exhaust flow, potentially boosting output power and efficiency.

How much weight can be removed?

The amount of weight removed from a car will vary based on the approach and components targeted. Balanced strategies look to shed significant weight without undermining key aspects like safety and comfort. Incremental steps can lead to substantial improvements over time.

Is it worth removing everything?

Comprehensive removal may compromise vehicle usability. It’s essential to measure weight removal against practical limitations and intended vehicle usage. For some, partial, strategic reduction offers the best performance gains without sacrificing too much convenience or increasing risk.
