We had the opportunity to trial a set of Mefro wheels on a customers T4 recently.
Using Spigot ring adaptors to go from the 66mm of the Mefro wheels down to the 57.1mm of the T4.
We like em if we're honest! And the low offset comared to the T4 stock wheels gives a nice "chunky" look.
15" Were very close to the caliper, but plenty of room on the 16"
