When you change wheel/tyre package try to keep as close as possible to the stock rolling diameter as a big deviation will show up in car speed. Eg: stock GTS = 625.3mm, the size Dan mentioned above = 637.2mm so a greater OD of 12mm which is OK but anything greater than this such as 20mm or more will throw gearing out slightly & you will lose the safe 3kmh buffer in your speedo.
I would also imagine that sticker rubber would achieve faster lap times if simply just replaced with same size.
