I was JUST looking at this over the past week.
There are some issues with it. Looking at the GTI layout, the cup holders are placed further back than the R, or the Euro GTIs. This gives space for the lid to roll back, and the handle to sit.
In order to get the R cup holder to fit, it appears that you will need to cut out the cigarette lighter and card holder thing that sits in front of our current GTI cup holders.
This in itself isn't a big deal for me, because I never use them. The issue is that this still doesn't guarantee that the cup holder will fit. However, I'm doing some more investigating and trying to see if it will work.
I've found some online from non-OEM sources. May give it a shot in a month or so.
