20mm wheel spacers are used to fix the wrong clearance issues. They are widely and successfully applied for decades. As long as you use genuine quality sets and install them correctly, they are essentially safe and reliable. Since wheel connection is an important element for a car, these 20mm wheel spacers will improve safety by correcting the wrong offset, clearing big brake caliper rubbing issues, adding more stability, and boosting the roller resistance.
Many people claim that wheel spacers are dangerous because they will be broken when facing fierce impacts. However, as the spacer industry develops, the strength of spacer has been greatly improved. For example, a forged 7075-T6 20mm spacer can withstand about 572 MPa stress without breaking. And some of the spacer wheel studs can bear a massive load of up to 1,220 MPa. With such strength and toughness, modern 20mm wheel spacers are just as safe as many aftermarket alloy wheels.
Are Forged 20mm Wheel Spacers Better Than Casting Ones?
In short, forged 20mm wheel spacers are better and safer than casting alternatives. In contrast to casting, a forged wheel spacer begins as a solid piece of metal referred to as a “billet.” This ensures the spacer’s structural integrity, meaning no porosity, shrinkage, and other micro-processes presented in the raw material. The forging process gives these 20mm wheel spacers inherent strength and durability against whatever you can throw at them during a lifetime of driving.
Unfortunately, most wheel spacer failure issues are blamed on cheap casting wheel spacers. This manufacturing process is cheap and fast. However, the gravity casting leaves the material full of irregular areas of density. Because of cavities, porosity, and shrinkage, casting 20mm wheel spacers lack the tensile, torsional, or compressive strength to stay within the safety factor of their properly manufactured equivalents.
What Are Safest 20mm Wheel Spacers?
When it comes to the safest 20mm wheel spacers, always choose the genuine brand set. Certainly, reputable manufacturers make nice wheel spacers. A genuine brand typically becomes a genuine brand because it has developed a reputation for high quality. The manufacturing process is strictly regulated, and factories only use processes that have been proven to be safe. The safest 20mm wheel spacers go through many safety tests before leaving factories, such as impact resistance, tensile strength, and hardness.
Impact resistance is the ability to absorb the shock from an accident without causing any damage. Tensile strength refers to the amount of load or stress that a spacer can handle before it stretches and breaks. These two main tests are intended to make your 20mm wheel spacers safer. High-end wheel spacers company express performance via data. Check the specifications before ordering. In addition, brand 20mm wheel spacers come with a warranty, which gives drivers peace of mind.
