Gibbo GTI, I'd say there are three options I can think of that will avoid the rubbing issue because you have a 'Sport' model.
1) Replace entire 'Sport' suspension with affordable second hand LR factory spec non 'Sport' dampers and LR factory spec springs then you can do what the other hippos can. Now add a lift kit. (E.g. DAP).
2) Fit more expensive Monroe shocks, that might be a little stiffer than stock LR items, lob on some second hand or new LR factory springs (again non Sport). The ride might now be less squishy than a standard Freelander, marginally. Now add a lift kit. (E.g. DAP).
3) Don't fit a lift kit using spacers and just get LR/Monroe shocks (replace your factory sport shocks) and add some stiffer 'Ironman' springs which is still about 1.5'' lift.
If you don't intend to take your vehicle off road and want a higher ride height but still want some stiffer ride quality (like a sport, but not as good because the dampers aren't 40mm lower remember), then I'd consider
a final compromise of: Monroe Shocks and Ironman Springs (to enable a future lift kit being fitted).
However, I'm not aware if you can then add the DAP spacer kit on top because this theoretically might give a lift of 3.5'' (89mm) which is too high. I think the highest ever lift sold, is 70mm and most say 50mm is maximum.
Maybe some other people can kindly let us know their thoughts.
