Wheel spacers are round discs that are installed between the rotors and wheels. The purpose of installing them is to widen the offset of the wheels, which widens the vehicle’s track. This has handling benefits even when the tire size does not change. A wheel spacer can be as thin as 3mm or as thick as 23mm. The range of sizes to choose from enables you to push your wheels out just as much as you need.
Between Hub Centric Spacers and Lug Centric Spacers
There are two different types of wheel spacers: hub centric and lug centric. The difference between both types of spacers is that:
- Hub centric wheel spacers are centered by the wheel hub. The bore hole in spacer precisely fits the wheel centering flange on the hub.
- Lug centric wheel spacers are centered by the lug nuts. The bore hole in the spacer does not precisely fit the wheel centering flange. Instead, it is usually several mm larger in diameter. Conical lug nuts must be used to attach a lug centric wheel spacer, and they should always be tightened by hand, using a star pattern.
Generally, hub centric wheel spacers are the more preferred option. They can’t be installed off center. It is possible to unintentionally install lug centric, off center, which results in vibration similar to a wheel being unbalanced. So why do companies even make lug centric spacers? Because some hubs have unique sizes and were made in low volumes. It’s not commercially viable to make spacers for low production vehicles with unique hubs. But if a spacer manufacturer can make one lug centric spacer that works for several different vehicle.
