Ben, you are going down the exact same route as me with the suspension. The reason why i sold you the V2s was because you cant fit the KW top mounts to them. The spring is a lot fatter on the V2
KW, VWR and pretty much all the other tuners i asked all said you cant even put them on V3's even though they do fit. Lots of reports of problems across Europe i believe.
Thats how i ended up with the clubsports. You can however buy other companies ones like White-line who sell them to fit most set-ups i think.
