Proper Wheel Offset



I plan on purchasing a set of staggered wheels (18x8.5F and 18x9.5R) but need to know which offset(s) will work.
The wheels are Mandrus Regenmeisters and are available with offsets (mm) of 25, 32, & 43 for the front and 25, 35, and 53 for the rear. I would like to maximize my front track width and minimize the rear if possible.
I am fairly certain the 32F and 35R would work, would it be possible to go with 25F and 53R? If so does anyone know if the wheels will stick out from the fenders?
Thanks.
How would I know what kind of offset to get for a car with 18 x 8 wheels and 18 x 10 wheels?
I plan on running this set up but I want to make sure I get the right offset for the back so I dont run too wide out back and beyond my fenders. Also, what exactly is offset, I have an idea but if someone could explain it to me that would be great.
Thanks
you can always add a spacer to reduce a positive offset, but there is no cheap fix for an offset to small
