I want to put 19X8 in the front and 19X9 in the rear of my 87 GT.

I am doing the lebaron brake conversion on the car so my front will stick out 7mm (thickness of the lebaron rotors) further than stock. The back will have coil overs.

What offsets will I need to use front and rear in order to keep the tires under the lip pf the wheel wells? They can meet flush with the wheel wells but I don't want them to stick out.

Be sure to add 10 mm to compensate for the rotors

I have seen that chart before and while it is a decent guide, it is not accurate.

Close enough.
You can always order an extra 5 mm of positive offset, then use 5 or 10 mm spacers to fine tune it.
If you don't like it, you make us one. One that's precise to the millimeter.
Nobody here can offer anything better than that diagram.
Because of this little but inescapable variable: production tolerances.
Use that brain your momma gave you, go get a wheelmate, and check your own, instead of lazily whining to us about Joe Torma's free gift to you.
