Wheel Offset

Wheel Offset
This question is for those of you who have put aftermarket wheels on you 3rd gens. What offset did you use? The wheels I'm looking at come with a 0mm offset, the wheels are 16x8". According to the wheel dealer, the offset for the stock wheels is 20mm and the new wheels are 0mm which they say puts the mounting right in the middle of the wheel. What does this translate into as to where the tire will be in the wheelwell? Any help would be appreciated before making any commitment to buy them..
Thanks in advance..

Stock 16" wheels are 0mm offset in front and +16mm offset on the rear. That's how the GTA wheels are and it should be the same for the Camaro wheels.
An 8" wide wheel with "0" offset should have approximately 4.5" of backspacing.
Here's how it works:
An 8" wide rim actually measures 9" from outside edge to outside edge. (Advertised rim widths are determined from measuring the distance between the inner beads)
So, an 8" wide rim with "0" offset will have 4.5" of backspacing. Next, there are 25.4mm to an inch, so 6mm is equal to about .2" (let's call it 1/4"), 12mm is equal to about .5" ...and so on.
Based on that, 16mm should be close to 5/8 or .625". Now, a +16mm offset should yield about a 5.125" backspace. I'd call it 5.25" to be safe.
One last thing to remember is that positive offset will increase backspace, while negative offset will decrease backspace.
