What do Subaru Forester wheel spacers do? Are Subaru spacers safe for 4×4 off-roading? How thick Subaru wheel spacers are best for Forester? Here we take this 2015 Subaru Forester SJ as an example. When it comes to big brake kits, wheel spacers are very useful. By moving the wheels and tires further from the suspension, the Forester 5×100 spacers create more inner wheel clearance which is good to prevent stock wheels from rubbing against bigger brake calipers, or other parts.

As long as you install the proper size spacer, running quality Subaru Forester wheel spacers on all four wheels is very safe. For OEM wheels and tires, it is recommended to use Subaru Forester wheel spacers that are between 15-25mm.

Aside from the base functions of the wheel spacers, BONOSS forged active cooling Subaru Forester wheel spacers are finished with active cooling grooves. When the wheels rotate, these grooves allow the external cold air to flow efficiently and continuously inside the wheel spacers to take away the heat. Therefore, it achieves the purpose of actively dissipating heat for the braking system. In this way, these BONOSS forged active colling Subaru Forester wheel spacers can improve heat dissipation efficiency, and reduce safety risks during driving.

Do Subaru Forester Wheel Spacers Hurt the Suspension?

Quality brand Subaru Forester wheel spacers won’t hurt the suspension. In fact, they are no different from a wheel with low offsets. BONOSS forged active cooling Subaru Forester wheel spacers are CNC machined, precision at 0.02mm tolerance. This improves the fit and functionality of spacers. They are designed with better multi-stage hub-centric lips. The hub-centric metal ring is machined to be multi-layers, and the bevels fit the corresponding hub flange, which eliminates any possible gaps. Thus, precise hub-centric Subaru wheel spacers will not cause any kind of vibrations.

What Types of Subaru Forester Wheel Spacers Are Best?

BONOSS wheel spacers are made of forged 6061-T6 or 7075-T6 billet aluminum alloy. The tensile strength is up to 572 MPa and the yield strength is up to 503 MPa (as strong as aviation aircraft). The higher the strength, the better the performance of wheel spacers. What’s better, BONOSS forged active cooling Subaru Forester wheel spacers provide ISO grade 12.9 wheel studs (most stock vehicle studs are grade 10.9) and ISO grade 10 lug nuts. They are strong and durable, enough to deal with daily driving, even off-roading events, and other scenes.
