i was wondering if you can help me. i searched, and was unable to find what i looking for. i need to find out if the stock lugnuts for an FD are of a tapered style or a acorn style. anyone happen to have a picture of their stock lugnuts, specifically the seating surface? it would be greatly appreciated. thanks for any information you can provide.

 

They have a straight taper, not the rounded style. I'm pretty sure that Mazda uses the same type of lug nuts on many of thier cars, Miata, Mazda 6, MX3, etc... Take a look in the wrecking yard.
