TeraFlex high steer setup... wheel offset?

Possibly aquiring a Jeep with this high steer kit on it... I need to know what wheels will fit and what won't. Obviously with the high steer knuckle stock wheels won't fit... How about 16" steelies with 4.25" backspacing? Anyone running this setup wanna chime in with what you're running and what you know will or won't fit?

are you sure stock wheels wont fit? they aren't the same as wj knuckles.

No, the tera knuckle has a much longer upper arm, but it is bent away from the tire.

Op: any reason you want to stay with a stock offset wheel?

Not sticking with a stock offset... the wheels I have are 4.25" backspaced 16" steel pro-comp wheels, stock wheels are 5.25" offset.

I just want to make sure my wheels will fit on this rig cause the guy is keeping his when I go to pick the Jeep up, so I have to put some wheels on it. His are 3.75" offset, so I'm not sure if that is the max offset or if I can run 4.25.
