Project Description


Effective performance upgrade! Yesterday, this Subaru Legacy installed BONOSS Forged Active Cooling Wheel Spacers, front 20mm (4/5″), rear 25mm (1″), PCD 5×114.3, CB 56.1. 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.

The Subaru Legacy is undoubtedly an excellent station wagon. It comes with a spacious, well-built, and comfortable cabin which gives the car a more enjoyable drive than other competitors. A 2.5-liter horizontally opposed four-cylinder engine is standard and makes 182 horsepower. Although every data is good enough to use, many car enthusiasts still choose to upgrade the OEM parts for better performance. And, installing wheel spacers is one of the easiest and most cost-effective options to get low and wide as well as to get flush the fender flares. Properly filled wheel arches can really make your car look wonderful. (Thanks CZC-RACING for providing these pics.)

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.

Dismounting Grooves Design for Effective Installation

Dismounting grooves means the small notches which are distributed on the corner of wheel spacers. It is designed to easily dismount the spacers, improving the user experience. Normally, it leaves a limited clearance between the axle plate and spacer, using a screwdriver can easily remove the spacers, simple and efficient. If there is no such groove, the spacer will snug the vehicle hub, by forces effect, it can be difficult to dismount. Even worse, you may destroy the spacers or axle hub. Furthermore, the grooves can act as an air collecting funnel, which is effectively increasing airflow, enhancing the heat dissipation effect.
