Project Description

Perfect fit! Last Tuesday, this Mercedes-Benz C260 installed BONOSS Forged Lightweight Plus Wheel Spacers, front 12mm(0.5 inches), rear 15mm(0.6 inches), PCD 5×112, CB 66.5 together with BONOSS Forged Grade 12.9 Extended Wheel Bolts. What do wheel spacers do? By pushing out the wheel, you can gain a small amount of clearance for mounting larger brake calipers without wheel scratching. Larger brake calipers bring better braking performance. Wheel spacers offer a cost-effective and efficient solution for your brake system modifications. These spacers and bolts are specifically made to give your car better cornering, aerodynamics, and look. (Thanks HFYI for providing these pics)


This Mercedes-Benz C260 W205 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.

Are wheel spacers safe for Mercedes-Benz C260 W205?

Exactly safe. Wheel spacers would only create the necessary distance on the inner portion of the wheel for clearance to solve the clearance problem of brakes, tie rods and other suspension components. If you plan to keep your current wheels and increase the offset of your car for enhancing the handling performance or exterior looks, then wheel spacers will be your ideal choice. Besides, hub-centric wheel spacers can transform a lug-centric wheel into a hub-centric wheel. They are sandwiched by the wheel and vehicle hub. To be considered safe, they will need extended wheel bolts to achieve proper thread engagement.

Why do extended wheel bolts do?

Extended wheel bolts (also called longer wheel bolts, extended lug bolts) are designed with longer thread lengths to allow full thread penetration with wheel spacers or wider aftermarket rims of a different offset. Any time you run wheel spacers, extended wheel bolts are a must option to properly secure the wheel to the vehicle hub. Without the proper thread length, the stock lug bolts will not allow penetrating the vehicle hub threads completely which can cause car shaking or safety risk. BONOSS Forged Grade 12.9 Extended Wheel Bolts are all thoroughly tested and certified by SGS, TUV authoritative institutions, truly guarantee safety.
