I am refreshing my E85 Z4 2.5i Sport’s M Sport suspension and was wondering whether to use Lemforder or Meyle front suspension arms, lollipops / bushes and track rod ends. Lemforder are nearly twice the price of Meyle at Autodoc. Also should I use new nuts and bolts and would antiroll bar bushes be needed, the car only having done 52,000 miles ? I have some new (to me) Ebach springs, top mounts, bump stops, front drop links and B4 shock absorbers to go on (purchased from a forum member). Is there anything else I should fit while I’m at it? Any advice would be appreciated.
