Project Description

Higher-level body control! Last Monday, this Mazda 6 Atenza installed BONOSS Forged Active Cooling Wheel Spacers, front 15mm (0.6 inches), rear 20mm (0.8 inches), PCD 5×114.3, CB 67.1. Wheel spacers are a kind of wheel accessories sandwiched between the vehicle hub and the wheel. It is designed to relocate the wheel outward from the wheel hub to solve the clearance problem of suspension components. They come in various thicknesses and dimensions, commonly used when the offset of the wheel is not ideal for your wheels. They are also a perfect solution for fixing bigger brake calipers clearance issues. Moreover, a better stance and a more visually aggressive look.  (Thanks KPZ for providing these pics)


The Mazda 6 is a delightful and dynamic midsize four-doors family sedan. The premium interior, comfortable seats, energetic power offers more enjoyable to drive than most of its peers. It is equipped with a 2.5-liter turbocharged four-cylinder engine, delivering 187 horsepower and 186 pound-feet of torque, a six-speed automatic transmission, providing fluent and sharp switch, front-wheel-drive.


Making no mistakes, the nimble handling, stable braking, and responsive steering make it still be one of the most fun-to-drive sedans in this segment marketplace. By increasing the track, they provide more stability and better handling performance. BONOSS insists on independent measuring and mapping for the most real, most effective, and most suitable First-Hand data. We have achieved precision control at 0.02mm. Producing wheel spacers with such precision can not only ensure high quality and safety but also provide a smooth installing experience.


What are 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. Most of the disadvantages that people associate with wheel spacers are actually blamed to lug centric spacers. Due to non-hub centric design, there is a certain gap between the axle and the hub, which means that the wheel is centered by the lug studs rather than by the vehicle hub. For some fierce impacts are strong enough to deform the studs, making the wheel no longer concentric with the hub, resulting in vibrations.

BONOSS Side Knurled Design Wheel Spacers

Knurling is a finishing procedure used to create any combination of horizontal, vertical, or crossing lines on the surface of components. BONOSS applied such process for enhancing both the exterior and function of wheel spacers. For decorative reasons, knurling can enhance the aesthetics of the wheel spacers by introducing an attractive pattern to the side surface. In addition to aesthetics, there are practical features. Knurling patterns can enlarge the side area so that it can contact more air, boost the heat dissipation effect, and also reduce internal stress.
