Ok that's a different matter all together. I suggest you contact the factory in Germany (the UK importer is not much more than a sales operation) and speak with a guy by the name of Michael Grassl. I found him to be extremely helpful and he really knows his stuff. I should point out that my Clubsports are fitted to an Evo V1 RS, but given Michael's knowledge of the product, I'm sure he will be able to give you some sound advice.
on S2000 i used compression 2-3 and rebound 7-8.
if the track is smooth and curbs are low - it was possible to stiffen the rebound even more.
as usual fine tune difference to achieve right front/rear balance.
