Are you having anything else done to them or just the powder coat? I Would love to have the rears made 11” wide but not sure if it’s going to cause me problems.The demo wheels on mine were 19s on 35 profile tyres.
The reason the Navis Holeys have slightly different hole sizes and numbers of, are because they weren't permitted to copy an Amarok due to some copyright laws apparently. Same as the aftermarket headlights don't look exactly the same as the factory.
As for my own Navis steels, I went 20" Schmoov because they were very marmite, and I have banded Amaroks, so wanted a totally different style.
