I'm someone that likes stiff rides, cough. In sense for as long as the road quality is good, as bumpy roads create more stress on the suspension and the rest of the car. For example, after a certain amount of time, rattling might come to existence, be it from exterior or interior, such as dash, doors, roof, consul, and etc. Nevertheless, I hate taking a turn in a car at low or high speeds and have/feel body roll as the car turns. So there exists the tradeoff. Further, I will also say that for me, the PP springs are soft.
