Project Description


Better handling for a classic car! Last Monday, this Mercedes-Benz E-class E220 W211 installed BONOSS Forged Lightweight Plus Wheel Spacers, front 10mm (2/5 inch), rear 15mm (3/5 inch), PCD 5×112, CB 66.6 together with BONOSS Forged Grade 12.9 Extended Wheel Bolts. What do wheel spacers do? If you have upgraded your brake system with bigger brake calipers and still want to keep the current wheels attached to your vehicle without scratching, you can use a set of wheel spacers. The wheel spacer is sandwiched between the car’s wheel and hub. By spacing the wheels out, it will provide more stability and better corner control to the vehicle. Properly filled the wheel arches can really make a car look excellent. (Thanks to the owner for providing these pics)

This Mercedes-Benz E220 W211 is a versatile small luxury car. The potent power, grand interior, and good fuel economy make it stand in the top third of luxury small car rankings. The W211 is powered by a 134-horsepower turbocharged 3.2-liter 6-cylinder V6 engine, delivering 251 lb-ft of torque, a six-speed manual transmission, offering smooth, sharp shifts, and it is rear-wheel drive. It provides an enjoyable and stable drive experience, effortless to deal with different road situations.


What is the function of knurling design on wheel spacers?

Knurling is a finishing procedure used to create any combination of horizontal, vertical, or crossing lines on the surface of components. BONOSS applied such a process for enhancing both the exterior and function of wheel spacers. For decorative reasons, knurling 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 also reduce internal stress. That means improving the performance, strength and durability of the spacers.

What are two-piece wheel bolts?

Two-piece wheel bolts consist of a standard bolt with an extended smooth shank and a ball/conical gasket above the threads. It is the same design as the new Mercedes and Porsche vehicles factory lug bolts. The gasket structure effectively eliminates the bolts loosening and abnormal sound caused by the PCD hole coaxially deviation between the vehicle hub and wheels while driving. Besides, the two-piece design has a strong matching characteristic, suitable for most factory or aftermarket wheels, ensure your vehicle wheels are secure and properly fastened every time they are removed and installed.
