i only fit genuine ford arms on mk5's and 6's as all aftermarket ones ive used tend to last no more than a couple of months before the bushes are shagged again whearas genuine ones last 5-6 years also mk 5's and 6's do tend to be really light and wallowy when everything is in good nick on them imho i really dont like the way they drive. still doesnt stop me using one as my daily driver tho lol!
