Dunno what shock Bean sells. AVO, Spax, GAZ and others have shocks for Europas. What f you know what spring rate and length you require, great. If you are not sure, I would recommend going to a Europa specialist.
Myself, I got my S1 shocks from Banks/Lotus Supplies. I specified AVO units with as close to stock springs as possible. Mostly worked well. Only trouble was with the poly bushes which perished rather too easily. AVO sent another set free but they didn’t last either so I switched to Merlin Motorsport’s HD bushes for AVO shocks and have been trouble free ever since.
I specified stock springs as I wanted a good ride for my primarily street driven car. Perfect! Best riding car I’ve ever ridden except for 60s and 70s Citroens.
