Please make sure I am right by going here... http://www.bigcustomwheels.com/info_specs.jsp

Then you put in the specs for my current wheel which is 17 X 7.5 with 35 mm offset. You would have to imagine the spacer in there that makes the mounting position more towards the car. Then if you change the offset to 20mm and get rid of the imaginary spacer...same place right?
The spacer moves the wheel out therefore reducing the ET figure. A 35mm ET + a 15mm spacer yields a 20mm ET. If you get a wheel with a 20mm ET then the wheel will be in the same place as with the other combination.

Remember a +35mm ET will move the wheel in 35mm from the center line. This is very common with FWD wheels whereas RWD wheels are in the +10mm ET area. If you are using a possitive lock style spacer then it is a safe option to have. If you are using a spacer with longer wheel studs then by all means get rid of it.
