I like the look of the wheel arch trim that you find on the GT2 RS but it would look wrong if I fitted them on my car which has the spider centre lock wheels. My wheels are 8.5 inches wide and so would not fill out the wheel arch with the trim fitted. My thoughts are to fit the 9 inch GT2 RS centre lock wheels which are wider but are am unsure of the offset, can anyone help ? In other words will the gt2 wheels fitted to my car help fill out the wheel arch plus the trim.
