One of the questions our Modification Experts here at ModBargains are asked most frequently is “Do I need Wheel Spacers? What Size do I need?”

When do I need spacers?

Spacers are used for correcting the offset of a wheel to the hub of a car. As we discussed in our post about Offset, At its simplest, the wheel offset, represented in millimeters (mm), is the distance between the centerline of the wheel and the face of the wheel hub. There are several scenarios that might call for the use of spacers.

For instance, certain wheels may not be available for your car in the proper offset, such as 5-Series or M3s which need a lower offset front wheels, and the only wheels available may be something like a +35 to +40 offset. By running a 10-15mm spacer, this corrects the offset and thus the wheels fit perfect.

Alternately, if your style leaves you inclined to want extra “poke” or aggressive fitment on the wheels, for instance a 335i running a +22 offset like the M3s (rather than the standard +33), spacers are the way to achieve that goal.

Does it matter what brand Spacers I use?
Actually, yes. The quality of spacers you use is important, as low quality spacers may vibrate or even deform under load. We recommend you use quality spacers, which is why we exclusively stock and recommend H&R Spacers.
