WARNING: The wheel locks being sold by Nissan for the 370Z are NOT the correct wheel locks. I had these very same locks on my 370Z Rays and after one month of driving with them the locks began to show signs of stress fractures around the locking pattern. One wheel lock completely sheared of from the pattern to a 1/4 inch down the lock shaft itself.
I took it over to the Nissan dealer and they indicated the locks that are required are shank-style and the ones being sold by Nissan as the wheel locks for a 370Z are not shanks and they need to be......and they
should NOT have the beveled tips but rather instead be straight shaft shanks.
In fact they showed me that these "Nissan 370Z wheel locks" don't even screw on far enough to make contact with the wheel to create locking pressure on the wheel. These wheel locks are they said in plain words the wrong wheel locks to use on the 19" Sport Rays application.
They told me that I have been driving around for a month in essence with just 4 lug nut on and that any cornering in the past month I was doing was putting severe stress on the "Nissan 370Z wheel locks" which was what was causing the wheel locks to fracture.
They indicated
the correct wheel lock for the 370Z Rays is the McGard
#21153 wheel locks as these are the correct shank length and shape in that they are straight shafts.
Fortunately no damage was done to the Rays while driving for the past month with the wrong wheel locks being sold by Nissan .
