When and how often do you notice this lightness of the rear in your GTD? On the track? Round town?
Can't for a minute understand why putting a bag of sand in a car would be deemed as beneficial or necessary?
Surely VW's engineers set the spring/dampers for the weight of the car... I am missing a point here?
I have the estate & notice the difference when given the same spec in the hatch as a courtesy car...
my estate is way better/planted...& I have a way lighter engine..
What you are forgetting is nothing to do with springs/dampers...but everything to do with weight balance/distribution...
GTD hatch heavy nose, feck all out back....
the best MK7 golf for weight balance is the "R" estate....I know a few years ago I did some calcs over on MK7 forums about this...
