I definitely think the 20mm Whiteline ARB is overkill unless you are a serious trackdriver. In Pax's case doing spirited driving on B-roads is not a place where you want the rear to go light. The back roads I know of in Skåne/Southern Sweden all have a lot of ditches and Road side trees, not to mention dirt and gravel left from Farm machines on the surface.
You could be passing over a crest into a steep left hander on tarmac with poor grip etc..
Understeer is safe and predictable, catching the rear when you are not expecting it to go is quite the heartstopper, and not something which you want to experience on the Road.. If you make the rear too light then you also loose the option to catch it on lift off, which is what most instinctively would do..
Just my two cents..
