About This Audi S4 Base 2004 Build
We love featuring real builds from real owners. This Audi S4 Base 2004 sits on a set of 18×8.5 / 18×8.5-inch XXR 571 wheels, and the result speaks for itself.
The owner chose XXR 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 Base builds come through WheelFront every month, but this one stands out. The combination of the exterior with the XXR 571 creates a look that balances aggression with elegance.
Fitment Breakdown: XXR 571 on the Audi S4 Base 2004
I walked up to this B6 S4 and immediately checked the stance. The XXR 571 wheels in an 18x8.5 square setup fit this German chassis surprisingly well. We see a lot of aggressive setups, but this conservative approach keeps the car functional.
The +35 offset sits flush enough to fill the arches without looking like a tuner disaster. It pushes the wheel out just enough to kill that sunken stock look. You get a clean profile that respects the original lines of the Audi body.
We checked the clearance on those big front calipers. The spoke design on the 571 gives us plenty of room to breathe. You will not deal with any annoying interference issues here.
The 57.1mm hub bore matches the B6 platform perfectly. You skip the need for those shaky hub-centric rings. This keeps the steering feel tight and direct on the highway.
Since the car runs stock suspension, you have a bit of fender gap left. It keeps the car drivable on rough streets. We appreciate that the owner kept the geometry simple and predictable.
I looked for signs of rubbing, but the tires clear the liners easily. Even under full lock, the 8.5-inch width avoids the plastic inner guards. It is a true bolt-on experience.
The barrel depth gives the wheel a subtle concave look that catches the light. It adds visual weight to the bottom of the car. It is a smart choice for a daily-driven S4.
What We Recommend for Audi S4 Base 2004 Owners
If you own a B6 S4, stick to the 18-inch diameter. Anything larger ruins the ride quality and bends too easily on our trash city roads. The 18x8.5 size remains the gold standard for this specific platform.
Aim for an offset between +30 and +35 for that perfect flush look. Going lower than +30 puts too much stress on your wheel bearings. Keep it within our tested range to protect your hub health.
Forget about staggered setups on an AWD Audi. We always preach a square setup to keep the Quattro system happy. It prevents drivetrain binding and lets you rotate your tires properly.
Tire choice matters as much as the wheel specs. Run a 235/40/18 tire to get that meaty, performance-oriented look. It protects the wheel lip from curbs and fills the gap nicely.
Avoid cheap spacers if you can help it. They introduce vibration and often require longer bolts that fail over time. Buy the right offset once and sleep better at night.
Style and Build Analysis
The custom finish on these XXR 571s elevates the whole car. It contrasts against the paint in a way that stock silver wheels never could. It feels personal and intentional.
The multi-spoke design brings a modern edge to the B6 body. It bridges the gap between classic German styling and a modern street look. We love how it updates the 2004 aesthetic.
Proportions define a build, and this one hits the mark. The wheels do not overwhelm the car, nor do they disappear into the shadows. Everything feels balanced and purposeful.
This S4 has a presence that demands a second look. It avoids the "too much" trap that ruins many other B6 builds we see. It is sophisticated, clean, and fast-looking.
Compared to the typical replica wheels, this custom touch makes the car stand out. We featured plenty of S4s, but this one feels like a driver’s car. It looks like it belongs on a mountain pass.
Why We Love This Build
This S4 captures everything we love about the B6 platform. The custom finish pops under the streetlights, making the wheels look like they belong on a much more expensive car. It turns a classic sedan into a real head-turner without losing its factory soul.
When the sun hits those wheels, the metallic flake creates a deep, liquid look that pulls your eyes straight to the fenders. It fills the arches exactly how an enthusiast expects. Every time I see this car, I want to grab the keys and hit the canyon roads.
Builds like this remind us that simple mods often work the best. This S4 is a perfect example of clean execution done right. It is a masterclass in daily-driven style.

Before You Buy: Fitment Checklist
We talk to Audi S4 Base owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 18×8.5 / 18×8.5-inch wheels fit my Audi S4 Base? 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 Base owners run 18×8.5 / 18×8.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
