I am looking at trading wheels (KH veradah) with a mate of mine that has a AU series three ute.

Couple of questions we need to answer first.

The rods has the same PCD, but is the offset going to keep the rim inside my guards?
He is worried that the verada rims are not going to have sufficient load rating for his one tonner. What is the load rating on the rada rims?

genuine verada rims wont fit AU as the center bore is too small.

Hmm, guess the whole idea falls apart right there.
I hadent the considered the centre bore diameter.

It generally doesn't come up in discussion as 3rd gen centre bore is smaller than virtually any Falcon/Skyline/aftermarket 5x114.3 rim - just grab a centre bore adapter and off you go. Going the other way will possess issues.
