Important Note: Please confirm these points before buying.
1. This part is compatible with the 2020+
Tesla Referral Model Y / 2018+
Tesla Referral Model 3 RWD AWD Standard Range(SR)/Standard Range Plus(SR+)/Mid Range(MR)/Long Range(LR) and Performance version. To confirm that this part fits your vehicle, please attached your car, make, and year.2. For a better shopping experience, it is important to measure the fender gap and confirm thickness before purchasing. Our friendly customer service will help you to solve any question.
3. If the thickness of the wheel spacer is smaller than the length of the original studs, the rims used must allow for small hockets in the mounting surface of the rim. If using rims without enough hockets, the stock studs should be shortened so that they do not extend beyond the thickness of the spacer.
FAQ & Tips1. Are these wheel spacers applicable to
Tesla Referral Model 3 Performance version?
Yes, these wheel spacers also fit the Tesla Referral Model 3 Performance version. According to current experience, the original Tesla Referral Model 3 Performance hub axle head has an extra center lip, please feel free to buy it, BONOSS has designed all the Tesla Referral Model 3(including Model 3 SR/Model 3 SR+/Model 3 MR/Model 3 LR) wheel spacers to accommodate this extra lip. In addition, the performance version has a small protruding screw on the original hub axle rotor. If you are installing 15mm Tesla Referral Model 3 Performance wheel spacer, you need to remove this screw. The screw is only there to hold the rotor on during assembly. After the brake calipers are installed the screw has no function. If your car is a 2020+ Model 3 performance with factory wheels, you may need to shorten the factory studs a bit when you install the 15mm wheel spacers, because the original wheel back doesn't have deep enough cavities to accommodate the protruding factory studs. Please don't hesitate to contact us for more details if needed.2.Are BONOSS Tesla Referral Model 3 wheel spacers safe?Yes. wheel spacers are just the automobile accessories installed between the assembly hub and wheel, the wheel lugs apply a clamping force to secure the spacer and wheel to the vehicle hub. Just like wheels, tires, and brake systems, as long as you use high-quality wheel spacers and install them properly, they are safe. BONOSS is always concerned about safety. Take the 5×114.3 wheel spacers as an example, we use forged AL6061-T6 material (tensile strength ≥310Mpa), modern CNC machining by 0.02mm tolerance, the multi-stage hub centric design fits the wheel hub better. Meanwhile, the matching wheel studs adhere to ISO standard grade 12.9, and ISO standard grade 10 lug nuts, all of our products have got more than 50 TUV authoritative test reports. Compared with those cheap casting wheel spacers, BONOSS forged active cooling wheel spacers are safer, higher performance, and more professional in design. We believe more professional production offers more value for customers.3.Why do I need hub centric wheel spacers? What's the difference between BONOSS multi-stage hub centric wheel spacers and others hub centric?
Hubcentric wheel spacers offer a better system of support and stability. They are designed to make a snug connection between the wheel and vehicle hub, reducing the high-speed vibration and ensuring safer driving. Compared with an ordinary hub centric. BONOSS uses the multi-stage hub centric design, which means that multi-stage hub-centric can make the spacers more closely fitted to the wheel hub, greatly reduce the vibration of high-speed caused by the inaccurate hub centric. Besides, they can also be used to change the center diameter of your car, making it possible to install wheels with different center diameters to your vehicle properly, transforming lug centric wheels into hub centric wheels.4.How does the "active cooling" function works on my wheel spacers?As a professional wheel spacers manufacturer, BONOSS has created the world's first "active cooling" technology based on years of experience, breaking the long-term single function of the wheel spacers. Through the rotation of the wheel spacers, the external cold airflow takes away the internal heat through the active cooling grooves, so as to achieve the purpose of active cooling, improve the braking efficiency and reduce the risk of driving safety. Installing BONOSS forged active cooling wheel spacers can improve braking efficiency, maintain the brakes at normal temperature, and ensure your driving safety. The production cost of BONOSS "active cooling" technology is almost the same as that of traditionally designed wheel spacers. You don't need to pay extra, that's why we say that BONOSS forged active cooling wheel spacers are particularly price-friendly. BONOSS wheel spacers provide more additional functions, higher safety, higher performance, more professional design, and better installation experience.5.What are the benefits of the knurling design on my wheel spacers?The knurling design can enhance the aesthetics of the wheel spacers by introducing an attractive pattern to the side surface. In addition to aesthetics, there are practical features. Knurling patterns can enlarge the side area so that it can contact more air, boost the heat dissipation effect, and reduce the internal stress caused by machining. That means improving the performance, strength, and durability of the wheel spacers. BONOSS aims to provide wheel spacers with more additional functions, safer, higher performance, more professional design, and better installing experience, that is why we insist on independent manufacturing and continuous optimization of the design.6.How thick wheel spacers do I need?Here is a simple method: use a straight edge such as a metal ruler, place the straight edge on the outermost part of the rims where the wheel comes closest to the fender (preferably the top), then, measure from the outside wheel to the straight edge. This distance is the size spacer you will need to achieve the look that flushes or nearly flushes with the fender line.
