Suspension springing and damping is very much a personal choice based on the use of the vehicle and road conditions it rides on. You only have to look at Formula one cars whose suspension setups cater for the characteristics of the motor racing circuits they run on. They are setup for maximum performance with little regard for driver comfort. At the other end of the spectrum is a car such as a Rolls Royce whose reputation is bolstered by it luxurious comfortable ride. So somewhere in between we with our Caterham cars have to decide what we want. Although we try all sorts of different coffee blends to find what we like, suspension setups and choice of its hardware is cost prohibited to try all the different makes and types. Some people will talk to providers and fellow owners who have suffered the pain of experiment. I am one of those who will do that then pay my money and take my choice.
