So if follow the JDM Stock Location of the Sports Rear Tow Location:

Then the crash bar tow hook location for the Nismo is approximately here as shown (A little below the license plate):

But if you look at the Nismo Challege one shown it's lower (Under the skirt); perhaps it's not the same location?

Yeah I just noticed that... no idea!!
They could have drilled or welded the tow hook on the lower end of the crash bar, moving it a few inches lower?

Maybe that nismo challenge one has something similar to this welded at the bottom....

So, to revive a dead thread... How did this turn out? :p

Im needing to do a rear mount as well.. Any fresh ideas or anyone with custom rear mounts that can help?

Bump.. Who's done a rear mounted tow hook?
