I've seen some five lug Zs around the gallery.

Is there a 5-lug conversion I don't know about? Or are they custom jobs.

I used the search function and found nothing.

Modern Motorsports has a conversion kit using 280 stubs. Here's the link to the rear ones.. couldn't seem to find the front ones but if they do the rears they ought to do the fronts as well......Or you could convert it over to the 280Zx front hub by using the lower section of the strut housing and spindle, either way will work....
