In the market, there are 5mm to 70mm Subaru WRX wheel spacers for the stock 53-57 offset wheels. Wheel spacers are sandwiched by the wheel hub and wheels, therefore they reduce the distance from the wheel center to the hub assembly. Essentially, the Subaru rim spacers subtract the offset. As a rule of thumb, a 1-inch spacer is approximate -25mm offset. The less the offset, the more the wheels will stick out from the wheel hub.
Each time when changing tire width, it is a good idea to consider a set of proper WRX wheel spacers to make the offset correct. As long as you use a quality set and install them correctly, the wheel spacers are no different than low-offset wheels. With Subaru 5×114.3 spacers, you can add more inner wheel clearance. This is effective in preventing bigger rims or wider tires from rubbing against fenders, shock absorbers, and other suspension parts.
Will Subaru WRX Wheel Spacers Hurt My Vehicle?
BONOSS forged active cooling Subaru WRX wheel spacers are CNC machined, precision at 0.02mm tolerance. This improves the fit and functionality of spacers. High-precision Subaru WRX spacers won’t hurt your car. For instance, a wheel spacer with a high-quality surface is easier to sit flush up against the vehicle hub and wheel. So, there’s no obvious gap between them. This is helpful to avoid high-speed wheel vibration. That is to say, precise Subaru WRX wheel spacers are the best option.
Aside from the above functions, BONOSS forged active cooling WRX wheel spacers provide additional advantages. Distributed in petal shape, the cooling grooves of the spacers allow the external cold air to flow continuously when rotating. Besides, the knurling surfaces eliminate internal stress which contributes to more reliable product mechanical properties. The crisscross knurling pattern enlarges the cooling area which is good for the active cooling effect. BONOSS knurling WRX wheel spacers boost the whole user experience.
Do Subaru WRX Wheel Spacers Need to Be Hub-centric?
When installed, Subaru WRX wheel spacers become the connection point of the wheel and hub assembly. Hence, you would need hub-centric spacers. For a perfectly suitable installation, BONOSS forged active cooling wheel spacers come with specific hub-centric rings for specific vehicle styles. This provides a stable connection between the axle and the wheel. Since there is no significant extra force, the effects of Subaru WRX wheel spacers on the bearing are within the safety standards.
Apart from the Subaru WRX wheel spacers themselves, the wheel studs are also important parts that secure the wheels. Generally, the higher the tensile strength, the more impact load the wheel studs can withstand, and the safer they are. To ensure safety, BONOSS forged active cooling Subaru WRX spacers come with ISO grade 12.9 wheel studs (tensile strength ≥1220MPa; ultimate tensile load ≥152,000N; proof load ≥121,000N). These SGS TÜV-certified wheel studs and lug nuts are completely safe to use.
