Mine's a lowly GTD. But if I were to go shopping for a GTi, i'd be speccing the Parkers, no question.
Agree with Jim, they are the most recognisable as a GTi wheel. Plus you get a better ride, cheaper tyres and less chance of kerbing them.
Not that I dislike the others, I just don't like them enough to spend £1,400 on 19 inch wheels and DCC when the Parkers look fine (to my eyes anyway).
