Default wheels, WHEELS! PLEASE HELP!

Help this newbie! On the inside of my ZO6 wheels it says: 17/8.5, ET56, FA162 and F/R.

The 17/8.5 is the wheel size, I think the ET 56 is the offset, I think the FA 162 refers to the manufacturer? (so says my tire guy) and the F/R indicates that it is a right front wheel.
My tire guy also says that it appears to be a GMC wheel. I'm not so sure. I thought they all said either Speed line or Alcoa.

Aftermarket wheel manufacturers, at least some, have a bad reputation. Who made my ZO6 Wheels? This is important, because if I have sub-par wheels I want to know about it. This wheel is on my '04 coupe.

Well, since an OEM factory Z06 wheel never came in a 17x8.5" size, it would appear that you have an aftermarket wheel. It sounds like you're probably correct about the offset marking, but as to the others,

By the way, the '02+ wheels have "Speedline" cast into the backside of the spoke. On the '01 Alcoas, the backside is just stamped "GM".

OE Z06 wheels are 17x9.5" (54mm offset), and 18x10.5" (58mm offset).


You have reproductions.
