About This Audi RS5 B9 Build
We love featuring real builds from real owners. This Green Audi RS5 B9 sits on a set of 20×10.5-inch Ferrada CM2 wheels, and the result speaks for itself.
The owner chose Ferrada for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of Audi RS5 builds come through WheelFront every month, but this one stands out. The combination of the Green exterior with the Ferrada CM2 creates a look that balances aggression with elegance.
Fitment Breakdown: Ferrada CM2 on the Audi RS5 B9
I stood right next to this B9 RS5 when it rolled into the show, and the stance is perfect. We are looking at a massive 20x10.5 setup that fills these arches with zero effort. The ET25 offset pushes the face out to the edge of the fenders without looking like a track-day disaster.
The Ferrada CM2 is a beast of a wheel for the Audi platform. These 10.5-inch widths demand respect when you install them on a B9 chassis. You get that deep, aggressive concave profile that turns every head on the street.
Clearance is always the big question with these massive RS5 calipers. These CM2 wheels clear the front brakes with room to spare. We checked the barrel clearance, and it sits perfectly flush with the hub assembly.
You need to watch your hub bore measurements on these cars. This specific build uses the correct center bore for the Audi hub, so you get zero vibration at speed. Don't cheap out on hub rings if you go this route.
The fender gap on this build is non-existent because the owner dropped it on coilovers. If you stay at stock ride height, this aggressive offset might poke a little too much for your taste. Lowering the car gives you that perfect camber tuck that makes the fitment look intentional.
Watch out for the inner fender liners on hard cornering. With a 10.5-inch width, you run a real risk of rubbing if your tire choice is too meaty. We recommend a slightly stretched sidewall to keep the rubber away from the plastic liners.
The spoke design on the CM2 creates a visual illusion of even more depth. It makes the RS5 look wider and more planted than it ever did on factory rollers. This is exactly how you dial in a B9 platform for a high-end look.
What We Recommend for Audi RS5 B9 Owners
If you want to replicate this, stick to the 20-inch diameter. Anything smaller looks lost in the massive B9 wheel wells. A 10.5-inch width is our gold standard for achieving that aggressive, flush look.
Offset is your best friend when tuning an Audi. We find that ET25 to ET30 is the sweet spot for the front and rear. Anything lower than ET25 and you start dealing with annoying fender rub issues.
Forget about staggered setups on an Quattro car. You need to keep your rolling diameters within a tight percentage to save your differential. Stick to a square 20x10.5 setup so you can rotate your tires and keep the drivetrain happy.
Tire choice makes or breaks this fitment. Do not run a blocky, square-shouldered tire on a 10.5-inch wheel. Go with a performance tire that features a rounded sidewall to give you that necessary clearance at the fender edge.
Most guys mess up by buying wheels that are too narrow. If you go 9.5 wide, you lose that signature Ferrada concave look that makes the CM2 so famous. Trust us, go for the 10.5 width and get the stance you actually want.
Style and Build Analysis
The color combo on this RS5 is nothing short of legendary. That deep, rich Green paint against the Brushed Bronze Ferrada CM2 wheels creates a high-contrast aesthetic that feels expensive. Bronze isn't just a trend; it elevates the darker, moodier tone of the green bodywork.
The CM2 design features those long, elegant spokes that reach all the way to the outer lip. This draws the eye directly to the center of the wheel where the aggressive concave profile lives. It balances the modern, sharp lines of the B9 front bumper perfectly.
We see a lot of RS5 builds, but most people play it safe with silver or black wheels. This Bronze finish adds a layer of sophistication that makes the car look like a bespoke project. It catches the sun in a way that highlights the machined texture of the spokes.
The proportions here feel dialed in. You can tell the owner spent time measuring the drop to ensure the wheel face aligns with the fender flare. It looks like a factory performance model from a high-end catalog, not a backyard experiment.
Road presence is about details, and this build hits every mark. The open-spoke design puts those massive RS brakes on full display. Every time the car rolls forward, the light dances across the bronze finish and brings the whole package to life.
Why We Love This Build
This RS5 is the reason we obsess over wheel fitment. When that Green paint catches the afternoon light, the Brushed Bronze wheels pop with an intensity that you just cannot ignore. Every arch is filled, every line is clean, and the stance is aggressive without being tacky.
We see hundreds of cars every month, but this one sticks in our minds because it feels complete. It captures that perfect balance of luxury and raw street presence. It makes us want to clear out our own garages and start a B9 project right now.
Stop overthinking your next set of wheels and just look at this machine. This is exactly what a high-performance Audi should look like when you push the envelope. Get the right offset, get the right color, and go drive the wheels off it.

Before You Buy: Fitment Checklist
We talk to Audi RS5 owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 20×10.5-inch wheels fit my Audi RS5? 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 Audi RS5 owners run 20×10.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
