Alternative dampers and springs anyone?

Im close to deciding on getting off the Bilsteins on my SV for an aftermarket setup.

Whenever I look around 7's at meets, its very rare to see alternatives fitted and I just wondered why.

Someone told me that generally Caterham owners are pretty conservative and dislike non factory stuff, IDK.

I know what Im planning, but just wondered who has played this game, thought about making the change or had anything to add ?

Simon’s advice was to mirror what a friend has, as his car and use are very similar to mine

Core one with digressive fronts and pregreasive rear springs ….
