What is backspace and offset.Also I want the widest will I can get but I don't have that much room,so would I want a low of higher backspacing.
 
I read that above ^^.I really don't understand it could someone just tell me which backspacing (high-Low) will let me get the widest wheel.
 
Someone can probably get you in the ballpark, but because of differences in assembly from car to car, it would be better for YOU if you learned how and measured it yourself. Because one person's results may well differ from yours. It's always best in this situation to get the exact measured results from your own car to determine exactly how much room is there. Here is another good site that explains it a bit more:

If someone just blurts out an answer for you, 1) it may well end up being wrong for YOUR car and 2) you will not have learned a thing.
 
What are you trying to put wheels on? I can help. Do it everyday. What brand of wheel are you looking at buying. Off the shelf wheels only come in a a couple differant B/S. a custom wheel can be set to your needs.

They go hand in hand

Backspace is distance from wheel lip/bead to wheel mount surface. Offset is the distance from the wheel width centerline to mounting surface.

8" wheel with the mounting area right in the middle has 4" of backspace and 0 offset

Move the backspace to 3.5" then the offset is -.5"
