Project Description


Effective performance upgrade! Last Friday, this Toyota Sienna installed BONOSS Forged Active Cooling Wheel Spacers, front/rear 25mm (1 inch), PCD 5×114.3, CB 60.1. 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.

The Toyota Sienna is undoubtedly a great minivan. It comes with all-new styling which gives the van a more SUV-like look. Generally, larger calipers with more pistons and larger brake pads will offer greater stopping power and shorter stopping distances than the smaller ones. And bigger rotors also radiate more heat from the larger surface areas. And Larger-size wheels can enhance steering experience and high-speed performance. Increasing wheel diameter generally means wider tire width as well, making the contact patch between tires and road larger, thus boosting grip. The owner of this Sienna chooses to upgrade with 19-inch RAYS wheels as well as AP Racing Brake Kits. (Thanks PERFORMANCE CENTER for providing these pics.)

Black Hard Coat Anodizing for Corrosion Resistance

Hard coat anodizing is a proven very useful electrochemical coating process that provides both predominant corrosion-resistance durability and an excellent exterior. The process provides the surface with better abrasion resistance, flame resistance, and smoother and harder finish protection than regular paint or metal plating. The black dye not only brings a premium appearance but also tends to be more lightfast. To be lightfast means that the colors will not fade as quickly. It is an ideal hard coating process for forged Aluminum wheel spacers which is the same as numerous high-performance industrial components.


Why do you need hub-centric wheel 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. This allows the wheels are truly central to the vehicle hub, meaning no high-speed vibrations through the wheels. Also, they can transform a lug-centric wheel into a hub-centric one. Meanwhile, hub centric wheel spacers also reduce the stress on the wheel studs or bolts, improving service life range.

Additional Information:

  • BONOSS wheel spacer thickness can be customized flexibly, which is compatible with most vehicles. Thus, if you would like different sizes of wheel spacers, feel free to contact us. This Toyota Sienna uses front/rear 25mm (1 inch), PCD 5×114.3, CB 60.1.
  • The matching wheel studs are made of JIS SCM44o high-strength steel, which features many desirable properties such as high strength, wear-resistance, excellent toughness, impact resistance, and high-temperature resistance. All BONOSS wheel adapter kits are matching with all necessary hardware components including wheel lug nuts or wheel bolts to suit your vehicle.
  • Each BONOSS product is printed with the logo of “BONOSS”. This offers an easy method to distinguish other fake and inferior products. At the same time, it also provides a way to find our after-sales service. Our products are 10 Years Limited Warranty (new products with 12 months warranty), which is an excellent and cost-effective choice for your car upgrades.
