11kg isn't particularly light. Probs not much difference in weight between them and yours tbh.
Most reps are around 12 or 13 kg, OZ's are a better wheel but do not suit a mk4.
Slightly off topic, but, what is the difference between split rim, 1 cast etc, the rotiforms seem to come in a variety of different ways to be made. But how do the different types affect the weight?
I am kinda swayed by em...I'm trying to imagine them in black
