Can anyone tell me what these are made of (steel, alloy, etc)? These are original 240Z mag wheels if this helps any.

Most likely cast aluminum.....

2Manyz --- Correct - I've welded on them before ( 6061 rod )

texasz,

I agree with 2ManyZs and JEFF, those wheels are not an original Z wheel but they are the right age to match any 240Z you like and they should be cast alluminum probably 14x6 or 14x7. The plus with these wheels is they are super strong and are great for motor sport off road.

My 2c

Cheers

I vote alum. also. Check and see if a magnet will stick to it.

Then if these were not stock were they a dealer option? I have seen these on dozens of Zs which just made me figure that they were stock.

So everyone seems to be voting aluminum which would make then good for racing since they are lighter than steel. Right?

I'm asking because I am looking for a Z to buy and would want two sets of wheels, one with street tires and one with my race tires and would of course want the ones for racing to be light whereas the ones for the street would not matter (except for looks).

The wheel in the picture looks like an old style Cragar brand "Mag" wheel. Those were not original on any car, but were an extremely popular aftermarket weel in the 70's. They were Aluminum, in spite of the name...

Dealer Option is correct. When the Z cars hit the car lots here in the states the dealers could not keep them in stock!! SO.....

Lets make a few extra bucks on these cars...... replace the stock steel wheels with the mags and jack up the price !!! That is the true story. Exelent rims by the way.
