Thanks for all the advice. While I would prefer to have hub-centric wheels like the OEM's, it appears as though most are running aftermarket wheels that are non hub centric. Every shop in my area claims they've installed non hub centric wheels in almost every application.
The wheels I'm considering I found in this forum. They're Raceline Renegade 6 Black
Raceline Wheels - Renegade 6 Black
Any advice on this choice would be greatly appreciated, as I know of nobody in my area running these wheels.
Their Tech insured me they will run true and that they have installed many on FJ's with no problems. The backspacing is the same as my OEM wheels at 4.5" and the center bore is 4.25" which will clear the FJ hub dia of 106mm (4.17").
As for offset...what is "offset"? I thought offset was the difference between the mounting surface of the wheel to the inner/outer rim. In this case, it's 4.5" from mounting surface to inner rim edge, or backspacing, leaving 3.5" distance from mounting surface to outer rim edge, resulting in a -1.0" offset. If the same wheel measured 4" inner and 4" outer, it would be 0 offset.
Have I been misled?
