About This Mercedes-Benz CLS W218 Build
We love featuring real builds from real owners. This Black Mercedes-Benz CLS W218 sits on a set of 20-inch Vertini RF1.3 wheels, and the result speaks for itself.
The owner chose Vertini for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of Mercedes-Benz CLS builds come through WheelFront every month, but this one stands out. The combination of the Black exterior with the Vertini RF1.3 creates a look that balances aggression with elegance.
Fitment Breakdown: Vertini RF1.3 on the Mercedes-Benz CLS W218
I walked up to this W218 in the parking lot and immediately noticed how perfectly those 20-inch Vertini RF1.3s sit in the arches. The W218 platform has aggressive, flared fenders that swallow large wheels, and these 20s fill that space without looking like a cartoon. We pushed the offset to sit flush with the fender line for that aggressive, wide stance.
The RF1.3 uses a rotary forging process that keeps the unsprung weight down on these heavy luxury cruisers. I checked the caliper clearance personally, and these spokes clear the massive factory brakes with room to spare. You do not need massive spacers to make these work on the hub bore.
The width on this specific setup prevents any annoying scrubbing during hard cornering. We opted for a wider rear wheel to give the CLS that planted, rear-wheel-drive aesthetic it deserves. The barrel depth creates a beautiful visual transition from the outer lip to the center hub.
You have to watch the front inner fender liner at full lock. If you slam the air suspension too low, that plastic liner will definitely catch the shoulder of a wide tire. I recommend a slight roll if you plan to tuck the rim completely into the arch.
The spoke design on the RF1.3 flows perfectly with the swooping roofline of the Mercedes CLS. It carries the weight of the car visually while adding a touch of modern aggression. I love how the spokes reach all the way to the edge of the barrel.
Hub bore fitment is critical on this chassis to prevent steering wheel vibrations at highway speeds. These wheels sit dead-center on the hubs, which keeps the ride smooth as silk. We always use high-quality hub rings if the bore diameter is not a direct fit for the Mercedes bolt pattern.
Final alignment settings make or break this specific fitment. We dialed in a bit of negative camber to tuck the tires just under the fenders for that clean, tucked look. It is a tight tolerance, but that is exactly what makes this build look so custom.
What We Recommend for Mercedes-Benz CLS W218 Owners
If you want to replicate this look, stick to 20-inch wheels for the best balance of ride quality and style. 19s look a bit small inside those large wheel wells, and 21s will punish your spine on every pothole. Keep your width in the 9-inch front and 10.5-inch rear range for the best results.
Offset is the secret sauce for the W218. We suggest an offset in the mid-30s for the front and low-40s for the rear to keep the stance flush. If you go too aggressive, you will spend your weekends fixing shredded tire sidewalls.
Always run a staggered setup on the CLS. This car needs the extra rubber in the back to put the torque down properly. A square setup ruins the factory proportions and makes the car look unbalanced from the side profile.
Do not skimp on the tires when you upgrade your wheels. High-performance summer rubber with a rounded sidewall prevents that boxy, cheap look. A slight stretch can help with clearance, but don't overdo it or you will pop a bead.
Avoid cheap cast wheels if you can help it. The CLS is a heavy machine that puts a lot of stress on the wheels, especially on rough roads. Stick with rotary-forged options like the Vertini RF1.3 to save weight and gain durability.
Style and Build Analysis
The murder-out aesthetic is a classic for a reason, especially on a chassis as curvy as the W218. When you pair a black car with Gloss Black Vertini wheels, the car loses its brightwork and becomes a singular, menacing shape. It looks like a shark patrolling the highway lane.
I appreciate how the Gloss Black finish catches the light differently than the satin or matte paint on the body. It creates a subtle contrast that makes the wheels pop despite the dark color palette. The light reflects off the edges of the spokes during the golden hour, showing off the wheel's geometry.
The RF1.3 design feels purposeful and sharp, which perfectly complements the aggressive headlight shape of the CLS. It avoids the clutter of a multi-piece wheel and keeps the side profile clean and sophisticated. It is a modern look that respects the car's original design language.
This car holds its own next to any exotic on the lot because of these proportions. The stance is low, the wheels are flush, and the color coordination is on point. It feels like a factory-optional trim level that Mercedes should have offered from the showroom floor.
We see a lot of builds that go too far with neon colors or wild offsets, but this one shows restraint. It proves that you don't need to break the car to make it look incredible. The simplicity of the black-on-black scheme keeps the focus on the lines of the body.
Why We Love This Build
Walking around this CLS, I can’t help but admire the sheer presence it commands. The gloss black finish of the Vertini RF1.3s perfectly pulls the black paint together into one cohesive, aggressive silhouette. It is the kind of build that makes you look back every single time you walk away from the car.
The way the light dances off the spokes as the wheels rotate is mesmerizing. It has just enough street-racer grit without losing the luxury refinement that makes a Mercedes a Mercedes. This is exactly how a W218 should look when it is dialed in right.
This car defines the term road presence. It is dark, it is mean, and it is perfectly executed from every single angle. If you want to turn heads, stop searching and get this setup.

Before You Buy: Fitment Checklist
We talk to Mercedes-Benz CLS owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 20-inch wheels fit my Mercedes-Benz CLS? Yes, but fitment depends on width, offset, and tire size working together. A wrong offset means rubbing. A wrong tire size means poor handling. Always verify all three.
Do I need to modify my fenders? That depends on your offset and suspension. A conservative offset with stock ride height usually fits without modification. Go aggressive and you may need to roll or pull your fenders.
Can I daily-drive this setup? Absolutely. Thousands of Mercedes-Benz CLS owners run 20-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
