Seems like youve decided on Conti - cant go wrong and for the price you should get a great result. Ive run them on German and Japanese brands All Seasons with great success .
on my 2017 GTI Ive run Faulken Winters for the first time and love them, although we've had a very light winter so far, but snow predicted the next two weeks.
I would agree with other member on the GTI to run Summers ( I am thinking of going with Toyo since my car came with A/S Pirelli's) since I like the Toyo tread pattern and my mechanics put lots of them on BMW and Audi's with great customer satisfaction on performance and price point.
There are so many great options and if money no opject go with Conti, Michelin, Pirelli since most big race teams and series use them.
Good luck.
