I finally got around to installing J&M CC plates, koni oranges, and sr springs on my car today (it only took me 6 months...ha).
I had a local shop do the install and kind of had to walk them through what all needed to be done (I probably should have just done the install myself).
Anyways the mechanics claimed I didn't need the fifth bolt on the J&M CC plates... and the instructions weren't all that helpful on the subject.
So does anyone know if the fifth bolt is necessary or what purpose it serves?
Here's a picture from American muscle's website (the fifth bolt is that big hexagon looking one):
