Installing 15mm spacers is a good idea to improve the wheel style and performance. By pushing the wheels out from the hub assembly, wheel spacers allow you to install wider, more aggressive tires that can better grip loose or uneven terrain. However, many owners still wonder: Are 15mm spacers safe for driving?
Let’s answer first. Yes, as long as you install them properly, high-quality wheel spacers are safe and reliable. Consequently, get proper wheel spacers installed, and you’ll be fine in most driving condition. In this blog, we will delve into the top 5 factors of installing 15mm spacers to help you achieve a safe fitment.
5 Pro Tips to Install 15mm Spacers Safely
Bolt Pattern:
If you use aluminum spacers with stock wheels, make sure the bolt pattern is the same as the OEM one. Specific wheel spacers for specific wheel hub. This provides a stable connection between the axle and the wheel.
Clean Hubs:
During the installation process, some people may leave rust on the rotors, and not rechecking torque initially. This will cause problems. It is highly recommended to make sure the vehicle hubs are clean and smooth
Proper Torque:
The REFERENCE torque specs for 15mm wheel spacers should be 83.3 ft-lbs for M12 bolts and 103.5 ft-lbs for M14 bolts. Set a torque wrench to the proper torque and then tighten each lug nut in a “star” sequence. This ensures your car is safe and reliable.
Check Tire Rubbing:
After installing 15mm wheel spacers, park the car on flat ground, rotate the steering wheel to one extreme position, and inspect the wheel well to check whether there are rubbing signs.
Re-torque Spacers:
It is always a great idea to re-torque the wheel spacers after 50-100 miles of driving. Regularly inspect the tightness of the lug nuts.
Who Sells the Best 15mm 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 15mm spacers comes 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. Forged Aluminum for Improved Durability
All BONOSS forged active cooling 15mm spacers are made of top-quality 6061-T6/ 7075-T6 aluminum alloy. The tensile strength is up to 572 MPa, and the yield strength is up to 503 MPa (AL7075-T6). The forging process eliminates the porosity, ensuring structural integrity. This makes them not easy to break. With an advanced manufacturing process, BONOSS can offer all cars the perfect wheel spacers without any quality compromise.
3. Strong Fasteners for Enhanced Stability
When it comes to safe 15mm 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 over 75 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.
In Summary: Safely Boost Your Car’s Performance with BONOSS
With BONOSS’s innovative active cooling technology, superior forged materials, and certified quality, BONOSS forged active cooling 15mm spacers undoubtedly the best choice for your wheel style upgrading project. Choose BONOSS and experience the difference—engineered for those who demand the best.
