BONOSS Forged Lightweight Plus Mercedes Wheel Spacers W221 S550 12mm Spacers Before and After (1)

The Mercedes wheel spacers are a kind of efficient and advantageous component when talking about suspension clearance problems. You can get more fun trying to get just the right look for your W221 S-Class. Wheel upgrades may be your first step. You find the right wheels, but they come with the wrong offset. They sit too far in or too far out. Or maybe you would like to add big brake kits, but the wheel rubs the big caliper. That doesn’t look right and absolutely not safe. Then, 12mm Mercedes wheel spacers will be your most cost-effective option. They will position your Mercedes wheels further away from your car to eliminate rubbing of the tires against the wheel wells. This is also very effective in process of adding bigger brake calipers.

Installing 12mm Mercedes wheel spacers is safe. The vehicle’s wheels are actually fastened to the corresponding wheel hub by a clamping force achieved by tightening the wheel bolts of each wheel. All forces will be transmitted through each vehicle’s hub and its corresponding axle. Therefore, the weight of the vehicle will not be placed on any 12mm Mercedes wheel spacers that are installed. To improve the safety of 12mm wheel spacers, it is recommended to use quality hubcentric 5×112 spacers and install them correctly. Quality Mercedes wheel spacers are made of aircraft-grade 6061-T6 or 7075-T6 billet Aluminum that is strong enough to avoid being the weak link in your setup.

Are These BONOSS Mercedes Wheel Spacers Fit My W221?

An important factor of Mercedes wheel spacers safety is the compatibility of the spacers. To ensure a proper spacer fitment, you should care about these two contact faces: one is the interface between the W221 spacer and the wheel hub of the car, and the other is the interface between the spacer and the wheel. The wheel hub on a vehicle means the central rotating part that holds the wheel in place. Generally, there is a protrusion from the center area of the wheel hub, which is used to center the wheel. The diameter of this protrusion is called “wheel center bore”. The length of the extended part is called “wheel hub height”.

Hubcnetric Mercedes wheel spacers come with a hub-centric lip as a transition point. The inside face of the lip matches the hub protrusion perfectly and the outside face of the lip fits the mounting face of the wheel snugly. So that the spacer will fit over the hub protrusion as well as the wheel. BONOSS Mercedes wheel spacers are machined with a chamfer on the interface of the hub-centric lip. The angle and width of this chamfer are made to contact the hub protrusion perfectly so that there is no gap or any deviation. Besides, the accuracy of the chamfer/bevel is 0.02mm, with a more precise surface, there is a more snug hub-spacer-wheel connection.

What Kind of Extended Wheel Bolts Fits Mercedes Wheel Spacers?

Running extended wheel bolts with 12mm Mercedes wheel spacers have no problems. The seat type is an important feature many people would overlook. It means the actual contact area between the bolt’s head and the wheel lug hole. Using a W221 wheel bolt with the wrong seat type would make the wheel simply not be fastened to the hub correctly. The most commonly found styles include radius, conical, and flat (“mag”). If you plan on running stock Mercedes wheels, you need extended wheel bolts with the same seat type as the stock ones. If you intend to run aftermarket wheels, then both radius and conical seats are possible.
