The rear hubs are different on the '16. Only one pivot hole and it looks like it has been moved a little.
Malin uses the aluminum hubs, which are more like the '15 hubs. This maybe why they are using the +1.50mm offset on the rear. Am I right Bent? Or do the two wheels actually have different off sets?
I have not had time either to do measuring but i recon if you use the '16 plastic hubs with 0.00mm off set (#365353) you may have the same rear track width as the '15 car. I have some of the hubs, just not the 1.50mm ones.
