ET vs Backspacing!

Hi Staffan,

backspacing is pretty easy, the measurement from the inner lip of the wheel to the mounting flange. If you compare a wheel with 4" Bsp and 2" Bsp, the track width is increased with 2" Bsp.

ET (Einpresstiefe in german) is always measured from the center of the wheel, positive ET means the track width is more narrow than if you use negative ET. The amount of ET is always measured from the center!

Hope this helps. So i think if these Volvo Wheels use ET -25 and you have to use the adapter.....the track width will increase too much.

What kind of wheel are you searching? Wheel vintiques has got the oem steelies with 4" Bolt Pattern.
