I plan to avoid the whole issue of lubricating the leaf springs by fitting the Suplex 5 Link rear suspension. Choice of Bilstein non adjustable or Quantum adjustables. At the moment I am leaning towards the Bilsteins as it seems the Quantums are more suited to those who give preference to on track use or really hard driving on good roads. According to PJB the Bilsteins are a more suited to sporty driving combined with comfortable touring (sounds like me).
The other issue influencing me a bit is that the adjustment of the Quantums is at the top so it means removing the tool tray if you want to change it. Not a big job but in the end I would probably try to find a "set it and forget it" setting.
