Zac88 Posted December 19, 2010 Share Posted December 19, 2010 was wondering what exactly wheel offset is? Link to comment Share on other sites More sharing options...
BAC5.2 Posted December 19, 2010 Share Posted December 19, 2010 The distance between the centerline of the rim, and the mounting surface at the hub. A positive offset means the centerline of the wheel is offset towards the centerline of the car. Negative offset (which Subaru's don't use) is the exact opposite. So a 48mm offset means that the centerline of the wheel is 48mm inboard of the hub mounting surface. That's why lower offset wheels stick out more than higher offset wheels.

Zac88 Posted December 19, 2010 Author Share Posted December 19, 2010 so when upgrading to a wider rim I need a higher offset? Link to comment Share on other sites More sharing options...
Drift Motion Posted December 19, 2010 Share Posted December 19, 2010 not necessarily... most likely you'll need a lower offset one otherwise the wheel will hit your suspension Link to comment Share on other sites More sharing options...
Zac88 Posted December 19, 2010 Author Share Posted December 19, 2010 ok well I am confused then, is the offset measured from the front of the wheel or the back to where it bolts on? Link to comment Share on other sites More sharing options...
