Offset: Offset is displayed as an ET value, which refers to the German phrase “Einpresstiefe.” ET indicates the distance between the mounting surface and the geometric center of the wheel (the symmetry axle), usually expressed in millimeters.
When the ET value decreases, the wheel will protrude further out. An increased ET value, on the other hand, results in moving the wheel location deeper into the wheel arch.
OEM Porsche Offset: Front Wheel = ET 50mm / Rear Wheel = ET 48mm
BST GT TEK Offset: Front Wheel = ET 50.75mm / Rear Wheel = ET 48.75mm
