If I have 19x10 inch wheels in the rear, with a 40+ offset(hypothetical situation), and I add a 15mm spacer..... what is my offset now?
I think that if you add a spacer, it should be 40+15 = +55. The lower the offset, the less fluched it goes inside the fender...

This is incorrect. Bunta is correct.
It's +40 -15mm = +25 overall offset. (Btw, this will definitely stick out past the fender on a stock bodied car)
The higher the offset the more the wheel goes into the fender (hence why the stock wheel offsets are in the +55 range and they are really far in past the fender)
The lower the offset the more the wheel sticks out away from the body of the car.
This is because offset is the distance from the centerline of the wheel to the back of the hub in millimeters. If you add a spacer, you are essentially attaching the spacer to the hub therefore making the distance to the centerline LESS.
Thats phat...I run 18X10 with a 43 offset and it is at the edge of the fender. I cant imagine what it looks like with a 15mm spacer. Pics?
