Wheel spacers are a kind of aftermarket components of one purpose: relocating your wheels outwards from the vehicle hub. They’re a simple and inexpensive upgrade that provides many advantages to both street cars and off-road vehicles. By sandwiching between the assembly hub and wheel, they create a gap that sets the wheel away to an ideal distance. This increases the distance between the left and right wheels. A wider wheel track offers better traction, leading to more stability and better handling performance, that is why they are often used on many racing cars.

For many car enthusiasts who pursue personality and extreme performance, changing wheels and upgrading the braking system is an instantly effective beginning modification. Wheel spacers allow for putting wider wheels and tires on for additional traction and better handling. These wheels are usually taller than the OEM ones. Without spacers, they might rub against the wheel wells or fender flares. Higher-performance brake kits are often bigger than the stock parts. A wheel spacer makes required room for a larger caliper that wouldn’t fit in the factory wheel space. They can also bring your wheels flush with the fender flares, creating a more attractive look that will stand out from OEM vehicles. Whether you’re a fan or not, it can’t be denied that appropriately fill the wheel arches can really make a car look excellent.

Hub-centric Wheel Spacers

There are a lot of options you’ll find with wheel spacers, but they are mainly classified as hub-centric spacers and lug-centric spacers. We recommend hub-centric spacers rather than lug-centric spacers. Hub-centric spacers offer a better system of support and stability. They are designed to make a snug connection between the wheel and vehicle hub, ensuring the hub carries the weight of the car instead of the studs or bolts. For some special vehicle hub styles, BONOSS has further optimized the design of the hub-centric spacers for fitting perfectly.

Most cars come with a ring-type hub structure design. But some new Porsche models are equipped with the three-fingered style hub structure. BONOSS wheel spacers are designed with Porsche style hub-centric locking fingers and notches on the back for perfect suitable mounting. These wheel spacers are truly attached to the vehicle hub, ensuring the hub carries the weight of the car instead of the bolts, meaning no additional force, no vibration, no annoying noise, less energy loss, less fatigue damage, longer service life. Considering this special construction, the traditional hub-centric wheel spacers may not suit properly the three-fingered style hub, leaving a certain clearance.

Some car models’ vehicle hub height may not fit the common hub-centric spacers (for example Mercedes-Benz W221 S550). For a perfect suitable installing as well as the elimination of vibration, BONOSS forged lightweight plus wheel spacers are made with a thin hub-centric design. They are undergone CNC 0.02mm tolerance machining to ensure the snug connection between the axle hub and the wheel. It is always simple to put spacers on, but you should be aware that nobody can make it perfect the first time. When you meet the problem that it is hard to slide the spacer into the axle hub, you can turn the spacer to another side, then align the axle, slide in, spin the spacer to polish the center ring of the spacer to make it smooth. Then, install again, you will find it become easier.

There are many universal wheel spacers manufacturers advertise that their spacers can perfectly fit all kind of wheel hub, in fact, that means those spacers do not come with hub centric ring. In most cases, spacers above 8mm need hub-centric, or the wheel cannot be firmly attached. In a high-speed ride, loose wheels are dangerous, and the steering wheel may shake as you drive. Your vehicle can become shaky and the wheels not secure. In addition, if the hub assembly is not forced properly, the steel can fracture and cause the wheel to come off.
