With the intricacies of performance tuning, dampers play a crucial role in enhancing a vehicle’s handling. As emphasized in several expert articles, “The right set of dampers allows drivers to maintain control while navigating corners and improves overall vehicle response.” This week, we delve into dampers, an essential component in creating a good-handling Mustang. If you missed the earlier topics, you can find them in our Frequently Asked Questions and Technical Tips section on our website.
It's important to clarify that we'll be discussing dampers, not dampeners. Often mistaken as "dampeners," the correct term in this context refers to high-performance struts and shocks designed for your Mustang. A dampener moistens, while a damper controls the inevitable vibrations resulting from suspension movements. If your dampers have become dampeners, it’s time to replace them.
Why is it called a damper?
The term “damper” describes the primary function of a shock or strut, which is to control the oscillation of springs by damping, or reducing vibrational energy. When springs experience compression or extension, they will naturally oscillate unless a damper mitigates that movement. A properly functioning damper suppresses these oscillations quickly, typically within one complete oscillation cycle. Without dampers, your Mustang would bounce uncontrollably over uneven surfaces, creating instability that is both unappealing and unsafe.
Understanding the difference between shocks and struts
While a shock serves mainly as a damper, it can secondary functions such as limiting suspension travel. Conversely, a strut is a vital structural component that supports suspension geometry. Removing a strut affects wheel alignment, while removing a shock does not alter suspension geometry. Most Mustangs are equipped with struts at the front and shocks at the rear.
How do dampers work?
The vehicle's suspension springs and mass create a resonant system, similar to the strings of a guitar. When a vehicle hits a bump, the springs oscillate until energy is dissipated by the dampers. On a guitar, a player can stop this oscillation by touching the strings, similar to how dampers suppress spring movement in your Mustang.
Diving deeper into spring oscillation
Dampers work by converting kinetic energy into heat. In vehicles with hydraulic dampers, a piston moves within an oil-filled tube, forcing oil through tiny orifices. Friction heats the oil as it flows, dissipating kinetic energy. The design of dampers can vary greatly, influencing their efficiency and performance.
Dampers maintain tire contact with the road, which is crucial for driving enthusiasts. Effective dampers control weight transfer during braking, cornering, and acceleration. Aerodynamics, suspension stiffness, and tire characteristics all relate closely to how dampers function.
Determining the correct level of damping can be complex. Too much damping negatively impacts tire grip and ride comfort, while too little creates instability. Suspensions generally require more damping force at lower speeds (during turns and braking) but less when traveling over bumps or when the suspension is under high speed.
Monotube vs. Twin-Tube Dampers
Monotube dampers consist of a single tube primarily filled with oil, while twin-tube dampers have two nested tubes, offering a separate low-pressure gas chamber. Monotube designs excel in heat dissipation, which is essential in performance applications, as they provide superior responsiveness during high intensity driving.
Pro Tip: Dampers impact not just ride quality, but also transient handling. They often have a more significant effect on ride comfort than springs.
Adjustable dampers permit users to modify damping settings. Single adjustable (SA) dampers change either rebound or compression settings, while double adjustable (DA) dampers allow independent adjustments for both. Using adjustable dampers can enhance a car's handling, especially in competitive settings, but tuning requires knowledge and experience.
Considering the vast array of dampers available, we focus on performance-enhancing options. While stock replacement dampers may suit basic needs, they lack the performance characteristics needed for spirited driving. We prioritize high-quality dampers such as Koni and Bilstein, known for their street and performance capabilities. Additionally, our in-house developed MM Dampers utilize superior internal components, providing tailored options for different driving scenarios.
Crafting effective dampers demands extensive engineering. Subpar dampers can adversely affect even the most refined suspension designs. For street applications, finding equilibrium between ride quality and handling precision is critical. Testing new damper prototypes on a shock dynamometer and on-road evaluations ensure optimal performance markers.
Our fixed valving dampers cater to the majority of our clients, ensuring they can enjoy their driving experience without excessive adjustments. While advanced users can appreciate custom tunings, fixed setups enable easier handling and allow drivers to focus on skill improvement.
Both dampers and springs work symbiotically in a car’s suspension system. The first step in performance tuning is selecting springs before determining appropriate dampers. For personalized assistance regarding spring rates, our technical team is readily available to guide you through the selection process.
