If you replace the springs and shocks you should be OK.
The self levelling springs are softer and the car will sag more when you load the back.
Self levelling is not just for towing, Any load in the rear will cause normal suspension to drop, Estates being worse due to the extra length behind the axle.
Self levelling shocks jack themselves up as you drive so the car stays level.
More stable and safer in theory.
Not checked mine yet but it seems to handle better than my old hatchback.
Understeers less, wheelspins less and that back end must be glued to the road.
