Ok, i really do not understand how rims work, how they fit on the cars, the lug pattern... i dont get it, i want to put new rims on my 91 z28 and i like alot of them but i dont konw if they would fit or not!

I KNOW that they are 5 lug nut pattern, i dont know how far the spacing is, could someone tell me? i have the stock rims on there now .... and i have no idea what they are so when i want to buy a new pair of rims, do i have to look for camaro rims???

for instance right now i want to buy these mustang saleen replica rims which are 5 3/4 lug pattern?

WHEELS are what tires are installed on Not Rims.

5 lugs 4 3/4 bolt pattern. If you draw a circle that went through the center of the lugs, that circle would be 4 3/4 in diameter.
Backspace depends somewhat on the width you want.
If you want to find some new wheels, pick some out with the right bolt pattern and 'we' can tell you the backspace you need.

Rims, Wheels, same thing.
