To narrow or not to narrow...

[Flash68]

Okay, I am a little confused after some research.

It seems many 1st gen Camaros which are minitubbed with 12" wide wheels and 335s are running a slightly narrowed rear end, but then some others are not. But it also seems the backspacing I am seeing on these 12" wide wheels are almost always the same (consensus after contacting several people is either 6" or 6.125"). How is this so?

FYI, I have a stock length Currie 9" and plan to run a modified "dog-legged" Air Bar 4 link with home-fabbed minitubs.

Can someone enlighten me here?

thank you
