The car spacers are wheel accessories for style and performance upgrades. Whether you’re planning to use them for daily driving or off-roading needs, if you use high-quality wheel spacers and install them correctly, car spacers are safe to use. By enlarging the track width, these car spacers enable the tires to better grip the road surface, you will feel more stable while cornering.
Besides, wheel spacers allow you to install bigger tires and larger brakes with no rubbing issues. This also gives your car an aggressive and rugged look. In this blog, we will delve into the top 5 factors of selecting good car spacers to help you make a wise decision.
Top 5 Factors of the Best Car Spacers
Proper Thickness:
Think about your goal. If you just need a little bit of wheel clearance to fit a big brake kit, a thin thickness like 3mm to 5mm is a good idea. If you plan to achieve a more aggressive wheel style, thicker spacers like 15mm to 25mm might be a better option.
Bolt Pattern:
Car wheel spacers are installed on the hub assembly and in return attach the wheels to them. In this case, the bolt pattern is an important factor. If you use car spacers with stock wheels, make sure the bolt pattern is the same as the OEM one.
Quality Material:
Not all car spacers are created equal. Always choose genuine brand wheel spacers that are made of forged 6061-T6 or 7075-T6 aluminum alloy. Besides, high-strength wheel lugs are necessary to safely secure the wheel spacers.
Hub-centric Design:
Hub-centric wheel spacers come with precise hub-centric rings to ensure that your wheels are properly centered and fastened. Precise hub-centric wheel spacers provide high surface integrity and stability, reducing vibrations and preventing potential safety issues.
SGS TÜV Test Reports:
Good wheel spacers should come with proper SGS TÜV performance test reports. SGS TÜV test reports = guaranteed quality and performance. Besides, most genuine brand car spacers usually come with a warranty. The longer the warranty, the better.
Who Sells the Best Car Spacers?
Safety, precision, strength, and experience are what makes BONOSS the best spacer manufacturer. For anyone seriously considering the performance potential of their cars, heat dissipation is something that should not be overlooked. BONOSS offers several key advantages that make their spacers a top choice.
1. Active Cooling for Better Experience
BONOSS forged active cooling car spacers come with heat dissipation grooves. When rotating, these grooves allow the air to flow between the spacers and brake rotors. The air takes away the heat to actively dissipate heat for the braking system. These BONOSS forged active cooling car spacers boost the cooling efficiency, reduce brake thermal decay, and improve road safety.
2. Strong Fasteners for Enhanced Stability
When it comes to safe car spacers, wheel lugs are important. The provided BONOSS wheel studs are made of high-strength forged SCM440 alloy steel. These wheel studs are approved by SGS TÜV authoritative certification reports:
- Tensile strength≥1,220 MPa;
- Limited life range test≥2,000,000 stress cycles without damage;
- Ultimate tensile load≥152,000 N;
- Hardness (HV)≥395;
- Neutral Salt Spray≥500H.
3. SGS TUV Tested for Guaranteed Safety
Made of advanced machinery and undergone a series of safety tests, BONOSS forged active cooling car spacers are approved by over 75 SGS TÜV test reports. These SGS TÜV-certified wheel spacers are completely safe to use.
