Hello! Johnny from sweden here!If you know that you will use your car on both the road and track, you need a coilover set-up with adjustable dampers, because the car will be way to hard for road use with a setting that is for track use. As Bilsteins not are adjustable, it,s not so easy to change setting for track days. Everything depends on how much money you have. you get what you pay for here, and i would recommend a set of Öhlins coilovers if you can afford them. I guess they cost around 2300 £ here in Sweden, but they are world class with separate gas cabisters and both compression and rebound adjustment.
