Any idea how where i'll get a locking wheel nut key for a mx5.
If it is factory fit the dealer should be able to trace the number and order one but cost = arm + 2 legs.
I would replace the nuts --- a guy on ebay sells nothing but chrome and locking nuts.
To get the old ones off if no easy way you need set of these in the end of an impact gun even a cheapo 12v Argos one.

I seem to remember mine cost £40+VAT from a dealer many moons ago when I had an MX5.
I wouldnt have minded so much if the original hadn't turned up a week or so later in the "safe place" that I put it
