Are Subaru Forester wheel spacers safe to use? What does a Subaru spacer do for wheels? Here is an example of this Subaru Forester: for big brake upgrades need. Although upgrading to big brake kits will provide a significant performance increase, they may not always fit stock or aftermarket wheels. In order to accommodate the larger size of performance brake kits, your Subaru Forester stock wheels often require the installation of wheel spacers 5×100. By pushing out the wheel, you can gain the ideal amount of clearance for a bigger brake instead of rubbing against it when mounting back the wheel. This also increases the track, which provides more stability for your off-road events. (Thanks to the owner for supporting.)

Are wheel spacers good or bad for my Subaru Forester? Many Subaru Forester owners often install wheel spacers to achieve more stability especially while turning or cornering the vehicle. Your Forester becomes more stable as the wheel spacer provides additional width for the wheel track. In this way, the weight of the vehicle is distributed on all the wheels equally which in turn improves the comfort of car handling. For better off-roading performance, the owner of this Subaru Forester upgrades to Brembo F50 brakes as well as front/rear 20mm wheel spacers 5×100. As a matter of fact, wheel spacers will be cost-effective when used to improve handling.

How does Active Cooling Design Work on My Subaru Forester?

There is a special design petal shape grooves that exist on the active cooling wheel spacers. The grooves can make use of the wheel spacers rotation to allow the external cold air to enter and continuously flow inside the wheel spacers through these aerodynamic arcs to take away the heat, so as to achieve the purpose of actively dissipating heat for the braking system. Through this way, it can improve braking efficiency, and reduce driving safety risks. BONOSS aims to provide products with more additional functions, safer, higher performance, more professional design, and a friendly experience.
