Will the vehicle be more stable after adjusting the coilover suspension?
2 Answers
Some car owners, in pursuit of comfort, set the damping of the coilover suspension to a very low level. The hidden danger of this is that during high-speed driving, the vehicle may experience unstable center of gravity, and there is a significant risk of rollover during emergency avoidance maneuvers. If owners blindly pursue a lower body stance by adjusting the suspension height too low, the chassis is highly likely to scrape the ground during driving, causing damage. A major advantage of coilover suspension is the ability to freely adjust the height and stiffness of the suspension. For professional racing teams, the height of each of the four suspensions is repeatedly tested and calculated, and adjusted according to the characteristics of the track. However, for ordinary modification enthusiasts, arbitrarily changing the consistency of the four suspensions may backfire, not only affecting the vehicle's chassis but also posing safety hazards to driving.
When I first installed the coilover suspension, the driving experience was truly different. For my daily city commute, the car felt much more stable at high speeds, especially when taking turns with significantly reduced body roll—no more scary swaying like before. The improvement in handling was noticeable, and emergency lane changes didn’t feel as nerve-wracking. However, the downside is that going over speed bumps or rough roads feels much harsher, and cabin noise has increased. My family in the back seat often complains about discomfort. If you frequently drive on mountain roads or highways, upgrading to coilovers does enhance stability, but for daily commuting, comfort is a trade-off. It’s also crucial to have a professional shop adjust the height and damping properly to avoid damaging the chassis. Overall, the modification improves driving stability, but you need to weigh it against everyday usability.
