7711160128 - it is the wishbone used in first Clio Cup cars - basicly it is the same to the one fitted to road going versions (probably just with RenaultSport logo, seriously doubt they've changed bushes in it but don't know for sure)
7711162592 - is the so called 2009 Evo - which is similar to road version but designed to accomodate ball joints (wchich alone cost serious money)
Cheers. An excellent response. I was wondering whether ours could use ball joints or not. If the ball joint sits in a pressed in sleeve, or if the actual casting is different. Can you tell from the information you have?
