Advantages and Drawbacks of Lowering Car Suspension

Lowering the suspension of a vehicle is a popular modification among enthusiasts. While it can provide several benefits, there are also significant drawbacks to consider. This article explores both sides of the argument to help you make an informed decision.

Advantages of Lowering Suspension

Better Handling: One of the primary advantages of lowering the suspension is improved vehicle handling. By reducing the center of gravity, the car’s stability and cornering abilities can be enhanced. This is particularly beneficial for sports cars like the Corvette and Ferrari, which are already designed with a low profile and excellent handling.

Enhanced Ground Effect: For racecars, lowering the suspension significantly improves ground effect downforce and lowers drag. This can result in increased speed and better overall performance on flat tracks. However, the benefits of lowering suspension for road cars are more limited.

Reduced Risk of Rollover: Lowering the center of gravity can make the vehicle more stable and reduce the risk of rollovers, particularly in heavy vehicles or those carrying a lot of cargo. This is particularly important in commercial vehicles where the weight distribution is a critical factor.

Drawbacks of Lowering Suspension

Rough Ride: One of the most significant downsides of lowering suspension is the reduced comfort. A lowered car will experience more vibration and harshness over rough terrain, which can lead to a bumpy and uncomfortable ride. This can be a major drawback for everyday driving and might not be suitable for families or those with fragile payloads.

Increased Vulnerability: Lowering the center of gravity can also make the car more susceptible to damage on uneven surfaces. Speed bumps, speed humps, and even driveway entrances can pose hazards. The car's lower profile can result in scraping or damaging the underbody and front bumper, leading to costly repairs.

Impact on Load Handling: For vehicles such as trucks designed to carry heavy loads, lowering the suspension can compromise the vehicle's load-carrying capabilities. The factory suspension is carefully engineered to handle specific loads and weight distributions. Altering this can lead to reduced stability and safety on rough or off-road terrain.

Practical Considerations

Lowering a car or truck by more than 38mm can significantly reduce its usability, especially for road cars. The increased height of speed humps and other obstacles can make driving more challenging and potentially dangerous. Factors such as the intended use of the vehicle and the legal requirements for registration also need to be considered.

Conclusion: While lowering suspension can provide improvements in handling and stability for specific vehicles, it is crucial to weigh the benefits against the drawbacks. For everyday driving, especially in urban or mixed environments, the comfort and safety issues may outweigh the handling improvements. It is often more practical to keep the vehicle within its intended design parameters and consider alternative modifications if needed.
