About This Audi S4 B8 Build
We love featuring real builds from real owners. This Silver Audi S4 B8 sits on a set of 20-inch Forgeline CF1 wheels, and the result speaks for itself.
The owner chose Forgeline for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of Audi S4 builds come through WheelFront every month, but this one stands out. The combination of the Silver exterior with the Forgeline CF1 creates a look that balances aggression with elegance.
Fitment Breakdown: Forgeline CF1 on the Audi S4 B8
I walked around this B8 S4 for twenty minutes just to soak in how these 20-inch Forgeline CF1s sit. The 20-inch diameter is aggressive for a B8, but it fills the wheel wells perfectly without looking like a cartoon. We see a lot of guys go smaller, but this setup commands attention immediately.
The width and offset here sit flush with the fender line, giving the car a track-ready stance. Because the B8 platform has decent room, you can push the offset to maximize that concave look. These Forgelines provide massive clearance for the stock S4 brake calipers, which usually stick out like a sore thumb on thinner spokes.
The hub bore on these is machined specifically for the Audi platform, so we get a perfect vibration-free fit. You do not want hub rings if you can avoid them, and Forgeline nailed the tolerances here. The wheel sits tight against the hub, ensuring every bolt stays torqued exactly where it should be.
The spoke design on the CF1 is open and airy, which draws the eye directly to the rotors. It creates a lightweight aesthetic that hides the heft of the B8 chassis. You see the deep barrel depth through the spokes, adding a layer of industrial grit to a classy German sedan.
The Eibach Pro spring kit drops the ride height just enough to tuck the top of the tire. This tightens the gap without ruining the geometry of the suspension. We measured the clearance, and you get a clean look without the constant headache of scraping your subframe on every speed bump.
Watch out for the inner fender liner if you decide to go wider on the tires. We noticed that under full compression, a massive tire could catch the plastic tab at the top of the front arch. A quick heat gun session or a slight trim solves that issue for good.
Forgeline builds these to take a beating, which is vital for the heavy S4. You can drive hard into corners and trust that these wheels will hold their shape. This is the definition of form meeting function on a B8.
What We Recommend for Audi S4 B8 Owners
If you own a B8, stick to an 18 or 19-inch setup if you want pure performance. However, if you want the visual punch of these 20s, make sure your tire sidewall is thin enough to avoid rubbing. We always suggest a 255 or 265 width to keep the steering feeling sharp and responsive.
Never run a staggered setup on an Audi S4 unless you want to cook your center differential. Keep the wheels square so you can rotate your tires and keep the Quattro system happy. Staggered looks cool on RWD cars, but it is a nightmare for an AWD drivetrain.
Get your offset right from the factory. Using spacers is a quick fix, but a custom-offset wheel from a brand like Forgeline is always better for the wheel bearings. We see too many guys ruin their hub bearings with massive spacers that push the wheel center point outward.
Tire choice changes everything regarding the final fitment. A square-shouldered tire will look wider than a rounded one, even if the numbers on the sidewall match. Match your tire brand to your driving style, and do not be afraid to roll the fenders if you want that extra bit of poke.
The biggest mistake we see is people ignoring the load rating of the wheel. The B8 S4 is a heavy piece of machinery, so buy wheels that can handle the weight. Cheap cast wheels will bend on our pothole-ridden city streets within a month of daily driving.
Style and Build Analysis
The Transparent Smoke finish against the Silver paint is a masterclass in contrast. It is not as harsh as a gloss black wheel, which can look like a black hole in the wheel well. Instead, the smoke finish shows off the detail of the CNC machining as the light hits the spokes.
This color combination feels sophisticated but dangerous. The silver body is clean and understated, while the dark wheels provide a brooding, purposeful edge. It turns a standard daily driver into something that looks like it belongs in the paddock at a GT3 race.
The proportions here work because the CF1 design is so clean. There are no unnecessary angles or fake bolts cluttering the face of the wheel. It lets the car’s natural body lines do the talking while the wheels provide a solid foundation for the stance.
We have featured plenty of S4 builds with bright silver or polished wheels, but they often look too soft. This Transparent Smoke finish adds depth that you just cannot get with standard powder coats. It changes shade depending on the time of day, moving from a deep charcoal to a light titanium.
Every time I look at this car, I see more character. It balances the executive luxury of the B8 with the aggressive nature of a tuner build. It is not trying too hard, yet it stands out in any crowd of modified cars.
Why We Love This Build
This Silver S4 stops us in our tracks because it refuses to be ignored. The Transparent Smoke finish catches the sun and creates a depth that makes the wheels look liquid. It is the perfect balance of street-car utility and show-car polish.
When you see the Eibach drop pulling the fenders down over those Forgeline barrels, you understand the vision immediately. It is not just a collection of parts, but a complete transformation of the S4 identity. Everything flows together without a single forced element.
This build proves that you do not need wild body kits to make an Audi look incredible. You just need the right set of wheels and the guts to do it right. Put these on your car and never look back.

Before You Buy: Fitment Checklist
We talk to Audi S4 owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 20-inch wheels fit my Audi S4? 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 S4 owners run 20-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
