I'm sure as far as coilovers go, they're solid. They are a reputable company. But from my limited research, even a good coilover will not last as long as a quality basic shock/strut, especially on the salty winter roads I deal with. It depends what you're looking for out of your setup. I need simple and durable and am willing to sacrifice the obvious advantages of coilovers to keep it that way. If someone is going to be tracking the car, likes being able to adjust ride height, and other things regularly, the coilover is the way to go. I need to install and be done with it for probably the rest of my time with the car.
