Disc offset is a special parameter in automotive terminology that characterizes the distance from the vertical plane of symmetry of the car wheel to the plane of application of the disc to the hub. It is advisable to familiarize all car owners with this parameter.

documentation of your car
Instructions
Step 1
To determine the disc offset, use a special formula: ET = a - b / 2. ET in this case stands for the distance you are calculating; a is the distance between the plane to which the disc is attached to the hub and the inner plane of the disc itself; b - indicates the total width of the entire disc. You can get absolutely any value - it can be negative, positive, or it can be zero at all. It all depends on the parameters of your car.
Step 2
If you decide to change this parameter in your car, always only decrease it, since an increase will adversely affect the braking system - with an increase, the disc goes deeper into the wheel connector and rests on the braking system. It is also not worthwhile to greatly reduce the disc overhang, since it will bulge outward a little, because of this, the disc may begin to cling to the wing. This is especially true when changing a positive value to a negative one.
Step 3
Be sure to be guided by the features of your car model and do not pay special attention to any standard advice on this topic - it all depends on the specific nuances that vary even in the same models. Also consider the moment with the suspension.
Step 4
Read the warranty conditions for your car - manufacturers often prohibit changing the wheel offset before the expiration of the warranty period. This is a significant change in the vehicle's design and could have unintended consequences if instructions are not followed.
Step 5
Best of all, entrust this to the specialists of service centers, who in the future will be able to guarantee you the quality of the work done. Also check with the manufacturer if this will void your warranty, be sure to mention the name of the service.
