This is the wheel bolt pattern size (the spacing between all of the lug bolts). Along w/ the fact that it's a 4 bolt pattern, not a 5 bolt pattern.4X114.3 (4X4 1/2)
Wheel offset. Basically, where the wheel hub piece is in relation to the width of the wheel. 0mm offset basically means that the hub is centered in the middle of the wheel. A +40mm offset means that the hub is centered more to the outside of the wheel (facing you, not facing the suspension). +40mm offsets work great for Honduh's, but not for our cars, the wheel/tires won't even mount onto the hub/lug bolts before the tires hit the shocks/struts.with an offset close to +0 (the factory rims are +8mm).
