Bangkok: On social media, drawbacks of using adjustable coilover struts are being shared, such as a harsh, bumpy ride, and potential noise in the suspension if not properly installed. Conclusion: True. Can be shared. The "Sure Before Sharing" center verified the information with Suramis Charoenngam, an automotive technology tester and expert.
According to Thai News Agency, car enthusiasts often prioritize changing or upgrading the suspension system to enhance the car's appearance and handling. "Adjustable coilover suspension" is a popular choice for many. However, information circulating on social media highlights the "disadvantages" of this type of shock absorber, such as a harsher ride, uncomfortable seating, or premature suspension wear. The "Sure Before Sharing Motor Check" program collaborated with automotive experts to verify these claims, providing crucial information for car enthusiasts to consider before making a purchase.
Adjustable coilover struts are shock absorbers and springs assembled as a single unit, allowing ride height adjustments by tightening threads on the shock absorber body. Higher-priced models also offer adjustable damping, providing a sportier look and sharper handling at high speeds.
Experts confirm that the disadvantages shared on social media are indeed true, and there are even more concerns than those being discussed. The key drawbacks include a bumpy and harsh ride due to stiffer springs and shorter shock absorber travel, resulting in direct impact transfer to the car body and passenger compartment. Passengers may experience motion sickness due to increased and rapid bouncing and pitching.
Other suspension components, like rubber bushings and ball joints, wear out faster as they bear the brunt of impacts not absorbed by the stiffer coilovers. There's also an increased risk of front bumper or side skirt damage due to the lowered vehicle height. Adjustable coilovers are costly, ranging from tens of thousands to almost a hundred thousand baht, depending on material grade and functionality. Improper installation or setup can lead to annoying noises if substandard equipment is used or if the mechanic incorrectly installs and sets up the components.
Experts advise potential buyers to weigh the fun, grippy, stylish, and sporty benefits against the harsher ride, potential higher maintenance costs, and the comfort of passengers or family members. Every accessory has its pros and cons, and thorough research is necessary to avoid future regrets.
