I found this forum while Googling / researching about future modifications.
My wife and I just bought a used 2018 MK8 ST3 with performance package. (It seems the original worked for Ford Sweden and checked every possible box when he made his order).
The car came with winter wheels & tires so excuses the 15inch wheels for now .
Just wanted to pop in and say hello!
Here is a photo during a rest stop on our 350mile trip home after buying the car (while getting around 43mpg - with luggage and 4x wheels/tires in the back)
