There are different Subaru wheel spacers: bolt-on types and slip-on types. Simply put, if you need above 1-inch spacers, professional mechanics will recommend bolt-on types. Because the bolt-on Subaru Forester spacers are bolted to the vehicle hubs with provided wheel studs. Then the wheels are secured on the Subaru wheel spacers with stock lug nuts. This ensures a safe thread engagement. You don’t need a set of new extended wheel studs.
On the other hand, slip-on Subaru wheel spacers simply slide over your existing wheel hubs, secured by a set of new longer studs. Due to such structure, they are made thinner. If you need around 3mm to 10mm Subaru Forester wheel spacers, slip-on types will do. They are primarily made for vehicles that use wheel bolts rather than lug nuts. So, the installation process will be a little complex.
Which Aluminum Subaru Wheel Spacers Are the Best for My Forester?
Quality aluminum Subaru wheel spacers are usually made of 6061-T6 and 7075-T6 these two variants. Both 6061-T6 aluminum and 7075-T6 aluminum are high-strength alloys for making high-quality Subaru Forester wheel spacers. These aluminum wheel spacers are one of the most popular Subaru wheel spacers available because of their good strength, toughness, hardness, and corrosion resistance.
Based on traditional rim spacers, BONOSS Subaru wheel spacers come with more useful designs, for example, the active cooling grooves. The active cooling grooves behind the spacers are boosting the heat dissipation efficiency, reducing brake thermal decay, and improving road safety. These aluminum Subaru wheel spacers are strong and durable, enough to deal with daily driving, even racing events, off-roading crawling, and other scenes.
Are Forged Subaru Wheel Spacers or Casting Spacers Better?
Forged and casting refers to the two main ways that Subaru wheel spacers are manufactured during the production phase. Each type is manufactured in a different manner and associated with different mechanical performances. Normally, we consider forged Subaru Forester wheel spacers are safer and better than casting alternatives. Because forged alloy rim spacers require stronger equipment and more time to perform thorough quality testing in-depth.
All BONOSS Subaru wheel spacers are forged with top-quality material. The forging process makes these Subaru Forester wheel spacers more durable and more resistant to corrosion and oxidation. Additionally, the spacer’s structural integrity is not compromised. This gives BONOSS forged Subaru wheel spacers inherent strength and durability against whatever you can throw at them during a lifetime of driving. Therefore, BONOSS forged Subaru Forester wheel spacers tend to have greater overall vehicle performance and enhanced fuel efficiency.
