Short story is I have a set of aftermarket s31 4 lug wheels [6.5 x 15 +38 offset] i wish to mount on my early s30. I have a set of 280z hubs and a non-turbo 4 lug 300zx. Both hubs have an offset different from my 240Z hubs.
I understand that the non-turbo 300zx has a .75 inch offset over the stock 240z. However, the aftermarket wheels [Fittipaldi] I pulled of a non-turbo 300zx have "ET 38" cast into the hub. I understand ET38 is a +38mm [1.5 inches] offset.
Is there any advantage to using the 300zx hubs or can I simply purchase wheel adaptors that are 1.5 inches thick? The plan would be to mount 205/215 x 65 x15 tires on these wheels.
This is not a race car; but, it does have a mild 6 L GenIII truck engine. Are wheel adaptors that thick safe to drive?
