Are Coilovers Worth It?

If the car is purposely built for circuit laps, then a set of advanced shock adjustable coilovers is recommended; it may cost premium, but the increase in stability over tight turns and high rates of speed is worth it. However, if the car is a daily driver, lowering springs should be used at most.

Are coilovers good for daily driving?

For a brief answer – no, coilovers are not really suitable for daily driving because they make your ride extremely stiff and uncomfortable. Although it's possible to adjust coilovers to make it acceptable for daily driving.

Do coilovers improve ride quality?

Absolutely not. Since most coilovers are also going to allow you to lower the ride height, the spring and shock rate should be increased to avoid the suspension crashing and bottoming out. Doing so will offer a performance bump to most any vehicle.
