The STI wheel spacers increases the track width. Assuming that the tires, brakes, or any other things remain the same, a wider track will lower the roll center of the car, thus providing a better rollover resistance. It tends to reduce the load transfer to the outside when cornering, which in general will increase traction.
Using STI wheel spacers to increase the track width boost cornering performance. Even you don’t change the tires, the more track width, the better the handling of curves and swerving. Generally, vehicles prefer to have wider track width to reduce the rolling tendency and to enhance stability. In this post, we list the STI wheel spacers torque spec for safe installation.
What Are STI Wheel Spacers Torque Specs?
Installing wheel spacers on WRX STI is not a difficult task, but it requires some tools and skills. You need to follow the instructions from the manufacturer and use a torque wrench to tighten the lug bolts to the specified torque values.
The REFERENCE torque spec for the STI wheel spacers is 113 Nm (83.3 ft-lbs). For some wheels or applications, you may need more or less tightening torque. So, it’s best to consult a tire specialist to ensure the exact torque spec before operating.
Pro Tips to Torque STI Wheel Spacers Safely
Use a Torque Wrench:
It is recommended to use a good torque wrench to tighten the STI wheel spacers to proper torque specs. Set the torque wrench to the manufacturer’s recommended value. Then simply turn the wrench handle until it reaches the torque mark.
Start threading the hardware by hand, then use the torque wrench to tighten spacer wheel bolts in a crisscross sequence. When the wheel nuts are properly torqued down, you will feel a click around the head of the wrench. Don’t trust an impact gun can settle everything down.
Re-torque Wheel Spacers:
It is crucial to re-torque your new STI wheel spacers after the first 50 to 100 driving miles. Then, just re-torque them every routine tire maintenance. By torquing each wheel nut to the proper torque specification, your new wheel spacers will safely function.
What Makes BONOSS STI Wheel Spacers the Best Choice?
High-end wheel spacers are produced with top-quality materials to provide optimum performance to the vehicle. For example, BONOSS forged active cooling STI wheel spacers are made by advanced machinery and undergo a series of safety tests before leaving the factory. BONOSS offers several key advantages that make their spacers a top choice.
1. Active Cooling for Safe Upgrades
A key advantage of BONOSS forged active cooling STI wheel spacers is the active cooling feature. These wheel spacers are designed with petal-shaped grooves. The grooves allow the external cold air to flow continuously inside the spacer when it rotates. The air takes away the heat, actively dissipating heat for the braking system.
2. Side Knurling for Enhanced Stability
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 forged active cooling STI wheel spacers boost the whole user experience.
3. Hard Anodizing for Maximized Durability
BONOSS forged active cooling STI wheel spacers are hard-anodizing to resist corrosion so that they can work well for a long time without any problems. The oxide layer that follows the anodizing process offers excellent protection. The black dye will not fade easily. BONOSS forged active cooling STI wheel spacers will serve you in the long run.
Final Verdict: Elevate Your Car with BONOSS
With these outstanding advantages, it’s clear that BONOSS forged active cooling STI wheel spacers offer exceptional safety, durability, and professionalism. Whether you’re upgrading the aesthetics or improving the ride quality, choosing BONOSS ensures that you get products that meet the highest standards of performance and quality. Your vehicle deserves the best.
