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 HRE RS309 wheels, and the result speaks for itself.
The owner chose HRE 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 HRE RS309 creates a look that balances aggression with elegance.
Fitment Breakdown: HRE RS309 on the Mercedes-Benz CLS W218
I walked around this CLS for twenty minutes, and the HRE RS309 fitment is perfect. We are looking at a 20-inch setup that nails the W218’s aggressive, sloping body lines. The 20-inch diameter fills the massive arches without turning the car into a bouncy castle.
We specifically measured the offsets to push these wheels right to the edge of the fender. You get that flush look that makes the car look hunkered down. The width is aggressive, but it keeps the handling sharp and predictable.
Caliper clearance is usually a nightmare on these big Benzes, but the RS309 barrel design clears the brakes with ease. You do not need massive spacers to hide ugly gaps here. The spokes provide plenty of room for those front calipers to breathe.
Hub bore sizing is spot on for the Mercedes platform. We hate vibrating steering wheels, so running the correct hub-centric setup is vital. This car feels planted at triple-digit speeds because the fitment is precise.
That barrel lip depth really changes the profile of the car. It gives the CLS a deep, muscular stance that the stock wheels just cannot touch. You notice the craftsmanship the second you look at the mounting point.
The suspension is lowered on a module, which tightens up the fender gap significantly. Because the wheels sit so flush, we had to be careful with the tire shoulder profile. There is zero rubbing, even when the air ride drops the car low.
You need to watch out for the inner fender liner if you go any wider. The W218 does not have infinite room to play with inside the wheel well. This build finds the absolute limit without crossing the line into stupid territory.
What We Recommend for Mercedes-Benz CLS W218 Owners
If you want this look, stick to a 20-inch wheel. Anything larger ruins the ride quality on our terrible roads. 19s can look a bit small on the W218's long, sleek chassis.
We always suggest a staggered setup for these cars. You want wider rubber in the back to handle the torque. It keeps the car looking proportional and maintains the factory driving dynamics.
Do not cheap out on offsets. We have seen guys guess their offsets and end up with wheels that poke out like a circus truck. Find a shop that knows how to measure a W218 properly before you pull the trigger.
Tire stretch is a common mistake we see every day. Use a tire that actually fits the rim width to protect your expensive HREs from curb rash. A little extra meat on the sidewall also saves your wheels from potholes.
Skip the cheap spacers if you can. If you order custom forged wheels like these HREs, have them built to your exact specs. It saves you the headache of alignment issues and vibration later on.
Style and Build Analysis
The Polished Dark Clear finish is a stroke of genius on a black car. It catches the sunlight with a deep, smoky luster that highlights the intricate spoke design. It is not just another boring silver or flat black wheel.
The RS309 is a classic design that feels right at home on a luxury cruiser like the CLS. It manages to look both sophisticated and menacing at the same time. You can take this car to a black-tie event or a local car meet and it fits in perfectly.
This car has a presence that screams high-end performance. The black-on-black-on-dark-clear color palette creates a seamless, mean look. Everything is cohesive, from the window trim down to the lug nuts.
We have featured a lot of W218 builds, but this one is special. Most people overdo it with carbon fiber and flashy parts. This owner kept it classy, letting the wheels do all the heavy lifting.
The proportions are exactly what the factory designers intended, just dialed up to eleven. It makes the CLS look like a predator waiting to pounce. This is how you modify a Mercedes without ruining its soul.
Why We Love This Build
This blacked-out CLS looks like a shark patrolling the tarmac. Every time the light hits the Polished Dark Clear finish, the wheels reveal a depth that makes the car look incredibly expensive. It is a masterclass in restraint and good taste.
We love this build because it feels finished. Nothing is out of place, and the stance is aggressive without being tacky. It is the kind of car that makes you look back twice every single time you walk away.
Seeing this car in person confirms that the right set of wheels changes everything. If you want to transform your own ride, start exactly where this owner did. This is the ultimate blueprint for the W218.

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.
