Many people are delighted with the sporty look that 15mm spacers bring. Aesthetics and performance are the main factors for anyone picking out wheel spacers for their cars. Changing the size of the rims can alter the look. Bigger wheels and tires make the vehicle look bigger and beefier.
Then 15mm spacers clear many issues that you may meet when replacing wheels. Certainly, they are good for your wheel safety. Wheel spacers must fit the vehicle, otherwise, it may worsen the performance. In this blog, we delve into the top 5 factors of selecting good 15mm wheel spacers to help you make a wise decision.
Top 5 Factors of Choosing the Best 15mm Spacers
Bolt Patterns:
When upgrading with wheel spacers, a vehicle-specific set is always the best option. Double-check the vehicle bolt pattern (PCD) in your owner’s manual before buying a set.
Wheel Offset:
It is a good idea to compare the difference from the desired offset to current offset. Giving an example, if you get a +45mm offset rim, then 15mm spacers change the offset to +30mm. The lower the offset is, the further the wheels are outwards from the hub assembly.
Longer Wheel Bolts:
Extended wheel bolts are necessary options if you use slip-on 15mm spacers. However, bolt-on 15mm spacers come with integrated wheel studs, which makes the installation process easier.
Forged Aluminum:
A set of forged 15mm aluminum spacers are lightweight, strong, and good in corrosion resistance. Always choose genuine brand wheel spacers.
Hub-centric Types:
Hub-centric 15mm spacers can create a firm and stable wheel connection. If you often take your car to the track, hub-centric wheel spacers reduce the chance of high-speed vibration.
What is the 15mm Spacers Torque Spec?
The REFERENCE torque spec of the 15mm spacers is 103.5 ft-lb for M14 bolts and 83.3 ft-lb for M12 bolts. This is just a reference value. Some wheels or applications may require more or less tightening torque. It is always a good idea to ask a tire expert to figure out the exact torque spec before operating.
Who Sells the Best 15mm Spacers?
With over 17 years of manufacturing experience and 1800+ drawing updates, BONOSS provides the best 15mm wheel spacers. There are several key advantages that make their spacers a top choice.
1. Extreme Lightweight Benefits
As we all know, the lighter the unsprung weight is, the better the handling capabilities. BONOSS forged lightweight plus 15mm spacers are machined with “Hollow Carved” holes. Compared with the previous production, they are at least 20% lighter. The weight of these BONOSS wheel spacers is quite insignificant, and they won’t damage any suspension parts.
2. Excellent Anti-corrosion Materials
BONOSS forged lightweight plus 15mm spacers are made of high-strength 6061-T6 and 7075-T6 aluminum alloy materials. These rim spacers have better thermal conductivity than steel ones. They are much lighter and much better in corrosion resistance.
To further prevent corrosion in wheel spacers, BONOSS applies a black hard anodizing surface treatment. It is ideally suited for aluminum to improve corrosion resistance. This process makes BONOSS forged lightweight plus aluminum alloy rim spacers more durable and corrosion-resistant.
3. Worry-free 10-year Warranty
Every genuine BONOSS forged lightweight plus wheel spacer is covered by a 10-year warranty. This 10-year warranty protects the customer’s interest and ensures product quality and safety. It is worry-free to use BONOSS forged 15mm wheel spacers.
