Default how do i figure up what offset wheels i need for a certain body?

Ok i have an hpi sprint 2 drift and a 200mm hpi s15 silvia body. I need to know how to figure out what size the offset of my wheels needs to be for the wheels to sit flush with the body. I was told before to measure from the edge of the left wheel hexes to the right wheel hexes and then measure the body from the top edge of the left wheel opening to the right wheel opening and then split the difference between the 2 measurements in half and thats the offset i need. This isnt makin a whole lot of sense to me tho because i took measurements with a digital caliper and these are what i came up with:

Chassis from edge of left wheel hex to edge of right wheel hex
Front= 172mm
Rear= 169mm

Body from top edge of left wheel opening to top edge of right wheel opening
Front= 197mm
Rear= 204mm

Now by this math, id need 12.5mm offsets for the front and 17.5mm offsets for the rear. I know these meazurement are way off because when i put 6mm offsets on the front of the car, they sit flush. So what am i doin wrong?

Sounds like you found the answer. 6mm offset fit flush. That is what I use. I bought a 190 wide car. I bought a 200 wide body. The 6mm off set looks good. I did have to modify the wheel opening on the front for the wheels to clear while turning. Only one mm off on each side. No big Deal.
