I'm fairly sure the 300z has the same wheel fitment as the 350z. My brother (who knows a lot more about cars then me) said the wheels on his 300z, which happen to be racingharts, will work on my 350z. His are 19x8.5/10, not sure about offset.

Calculating the offset of a wheel is a fairly easy mathematical equation. First, measure the overall width of the wheel (remember, just because a wheel is 18x7.5, does not mean that the OVERALL width is 7.5”. It means that the measurement between the outboard flange and the inboard flange is 7.5”). Next, divide that width of the wheel by two; this will give you the centerline of the wheel.
Overall width/2 = Centerline
After determining the centerline, measure from the hub-mounting surface of the hub to the edge of the inboard flange (if the wheel were laying flat on the ground – face up – your measurement would be from the ground to the hub-mounting surface). This is your back spacing.
Back spacing - Centerline = Offset in Inches
Inches x 25.4 = Offset in mm
