Just curious if any rim that will fit on a 510 will also fit a 240Z.

Only thing I know about it is that stock, the 510 took 13" rims and the Z took 14".

Bolt pattern is the same too. (114.3 X 4)

I have no clue about offset or backspacing on a 510

I found these on EBay and couldn't believe no one had bid on them yet. I was curious if they would fit on a 240.

I suspect that they would, but I'm no expert. Wats usually go for big bucks in the USA. These are located in Tokyo and shipping is going to cost $300 to the USA. Watch the bids fly in the last 12 hours.
