I just bought a new spider Lusso and wanted wheel locks. There are none. That seems incredible to me. Does anyone know the size of the nut so I can possibly find them aftermarket?

Im waiting for the mopar version to come out.. hopefully soon.
I havent looked into others. Id guess that the mazda mx-5 locks would fit.. You could stop by the mazda dealer and find out.

smart, you are!

My dealer said I could get them from Mazda.

I have the mopar locking wheel nuts fitted. But " is there a design fault?"

I was never happy with the appearance - they look too big.

Tonight I have taken one off the car and weighed both locking and standard nut.

Standard nut is 30 gms
Locking wheel nut is 75 gms. A difference of 45 gms.

I understand that this is an extra 45 gms at a radius of 50mm from the hub centre,
but will it make a significant difference to the dynamic balance of the wheel?

Over to the wheel and tyre experts.

Now that's service!

Has anyone here ventured past Mopar/Fiat/Mazda on locking wheel nuts? There has to be some other options out there, even options that don't have key patterns that are common to come by, which can go a long way, just make sure you have more than one key just in case!

You guessed right, I have them fitted to mine.

My dealer threw them in free without asking.

My local dealer (Burlingame Mazda) had no problem getting the Mopar one's for me. Only took overnight to get them.

While installing the lock nuts on the Abarth, I noticed the original nuts and lock nuts size of the socket i not the same. Also noticed that size is in Inches not metric.
Original nut socket is 13/16"
lock nut(fiat mopar part) uses 3/4"

you could use I think 20mm and 21mm, but a bit loose.
