Conversion from Air Struts to Coil Springs: Impact on Ride Smoothness and Handling
When considering a suspension conversion from air struts to coil springs, many car owners are curious about the impact on ride quality and overall car handling. This article explores the differences between the two, based on personal experiences and insights from experienced mechanics, and highlights the potential outcomes for different vehicle models.
Smoothness and Ride Quality Comparison
Many people report notable differences when converting their cars from air struts to coil springs. In a 2008 Lincoln Town car, the change in ride quality was significant, but not completely noticeable. The car's suspension system, which utilized air struts, provided a very smooth ride, especially over bumps or railroad tracks. After the conversion, the ride remained comfortable, but a slight decrease in smoothness was observed. For a 10 on a smoothness scale, the suspension was rated at 9 after the conversion. This indicates that the upgrade is positive but the difference is subtle.
Unexpected Issues Post-Conversion
A noteworthy issue that some drivers may encounter post-conversion is the potential for hardware to come loose. For instance, the nut, washer, and bushing on one of the shocks in a recently converted Lincoln Town car had detached. While this might not be a common occurrence, it serves as a reminder to be vigilant and inspect the car periodically after making such a conversion.
Impact on Specific Vehicle Models
The impact of a suspension conversion from air struts to coil springs can vary widely depending on the car model. In the case of the Range Rover P38, a completely different result might be observed. The ’P38’s suspension, despite its apparent crudeness, is actually quite sophisticated. The live axle design comes with some benefits, such as improved center of gravity and better handling at higher speeds. However, converting to coil springs dramatically changes the car's ride and handling characteristics. The car may experience a worse ride, poorer high-speed handling, and reduced off-road capability.
General Observations and Considerations
For many Ford models, a suspension conversion often goes smoothly and can enhance the ride quality without significant impact. The Fords have a suspension system that can be compared to a comfortable, yet slightly bouncy, living sofa. This type of suspension can be remarkably smooth, especially on long highways. While the ride might not feel entirely the same after a conversion, the car will still perform as expected.
One should be cautious, however, as not all conversion kits are equally effective or tailored for the specific needs of different vehicles. Some off-road enthusiasts who think additional ground clearance alone can compensate for poor driving abilities may end up disappointed. Major manufacturers spend years developing suspensions that work well under various conditions. Kits from conversion companies often lack the expertise and thorough testing required to manage these conditions effectively.
Conclusion
While converting from air struts to coil springs can slightly alter your car's ride quality and handling, it offers many benefits. It is crucial to be aware of the potential issues and to monitor your car regularly. For specific vehicle models, the effects of the conversion can vary significantly. Engaging with experienced mechanics and thoroughly researching the conversion process can help in making informed decisions.
