hello Lowflyer,
we have both ,the 5 link system on the AR and the normal suspension on our +4 , 2008. We have the +4 since 2 monds and afther 2000 km I(and 550km weekend Ardennen /Luxemburg )have changed the frontsuspension to the Suplex of which I am very ,very satisfied(thanks to rid967 TM member how sold it to me). The rear on the +4 is ok . The car has done 6500 miles now. But,.... the 5 link of the AR is total different , much better in evriting ,BIG different, my opinion, worth to change
