There were 4 of them,2 in each side.Does anyone know what these are?The car is NbFl
Thanks in advance

Good that you put in that strut bar for your car with shocks.

Yes, it works fine with PSS9 but I am trying to find out what those things are.

Hustler is trying to tell you that you are doing it wrong. The Miata MX5 does not need a strut tower brace because the car does not have struts. Since the car has upper and lower control arms and not only lower control arms and struts, there is no sideways force on the top of the shock and no need for a brace.

And I do not know what those pieces are you have in your picture. My '96 NA does not have them.

Ok,thanks for the answers.Especially for hustler's.Just wondering what those things are.
