Congrats bud,
To be honest, I was looking for the single slat and FB marketplace there is a place in pretoria which has a set. However when I spoke to
@FiRi@Rennzport, he told me that I was looking for something that will take us back to early 2000s ha ha and dual slates are better suited so I got a set from him and when fitted, I didn't regret it. It suits the G01 much better than the single slats and I was head strong on getting the single slats initally. It really does improve it a lot and give it an aggressive feature.
Have a look at mine on my thread:

The only thing that I would also do while the grilles are out and you can consider this too is to wrap the crash bars behind the grill in glass black also. I will be doing this soon...so the grilles look more pronounced.
