what backspacing and offsets?

I was just wondering what backspacing and offsets would fit our cars without any mods?

-Thanks in advance

You can go with 15x10s on the rears if you use a 5.5" backspacing. This will keep the tires tucked under the fenders... any less you get the getto look where they stick out... any more you have fitment issues unless you have a 4th gen rear since they have different width than 3rd gen.

Might be helpful if you included the rim sizes you want to add and the rear you have under the car.

you can go 15x10 with 6" or even 6.5" of backspacing if you are willing to compromise a few things.

I was thinking maybe 17" x 8" with 5.5" backspacing and disk brakes...would this work? anyone know about the offsets?

...I'm confused

so our cars have to have 0mm offset infront and positive 16mm offset in the back?
