Hi has anyone got an idea what locking nut this is and how to get it off I have got them on with BBS RA's the person who I brought the car off had lost the locking nut and I need to take the wheel off to check brakes and do some work on the car....I am however finding it hard to get a key or know what key to even get for this locking bolt, I would like to be able to use these nuts again so don't really want to break them in anyway but really need them ASAP.
Thank for anyone who can help with this issue.
