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 18×10 / 18×10-inch GMR SF2 wheels, and the result speaks for itself.
The owner chose GMR 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 GMR SF2 creates a look that balances aggression with elegance.
Fitment Breakdown: GMR SF2 on the Audi S4 Base 2004
I walked around this S4 for twenty minutes just to soak in the specs. Running an 18x10 square setup on a B6 chassis is a bold move that pays off. We rarely see this much meat tucked under those factory fenders.
The 25 offset pushes these GMR SF2 faces right out to the edge. You get that flush look without needing massive spacers to clear the suspension. It sits exactly where it needs to be for a true aggressive stance.
Caliper clearance on the 2004 S4 can be a nightmare with custom multi-piece wheels. These SF2s clear the front brakes with just enough room to breathe. I checked the barrels and saw zero signs of contact against the uprights.
The hub bore fits the Audi 57.1mm center perfectly. We hate running hub-centric rings if we can avoid them, so this fitment is spot on. It eliminates vibration issues before you even head out to the highway.
You have to watch the fender liners with an 18x10 setup. At full air-out, the tire shoulder sits millimeters from the inner metal. I would roll the front arches just to be safe if you plan to drive low daily.
The lip depth on these 10-inch wide barrels creates a deep dish look that feels period-correct. It gives the S4 a wider, more planted aesthetic. It changes the whole vibe of the car compared to the stock Avus wheels.
Running air suspension makes this fitment possible. You can dial in the camber to tuck the tires when parked. When you air up, the geometry shifts just enough to keep you driving straight.
What We Recommend for Audi S4 Base 2004 Owners
If you want this look, start with the right wheel width. 18x9.5 is the safe limit for most guys, but 18x10 is the king of the hill. Do not fear the 10-inch width if you have the right suspension.
Aim for an offset between 25 and 30 for the best results. Anything higher than 30 will force you to run spacers that ruin the scrub radius. We always prefer a native offset that fits the hub correctly.
Staggered setups look great on paper, but a square 18x10 setup is better for this Audi. It lets you rotate tires and keeps the Quattro system happy. You want consistent grip at all four corners.
Don't skimp on your tire choice for this build. You need a slight stretch to clear the fender lip when you drop the air pressure. A 225 or 235 tire width works best to achieve that clean, tucked profile.
Avoid buying wheels without confirming the brake clearance. The S4 brakes are bulky and will catch on the wrong spoke design. Trust me, you do not want to realize your new wheels don't fit during the install.
Style and Build Analysis
Chrome on a German sedan is a risky play that usually fails, but not here. The GMR SF2 design is classic enough to pull off that high-polished shine. It pops against the paint and reflects the pavement perfectly.
The multi-spoke face adds a layer of complexity to the S4’s otherwise simple lines. It feels like a high-end build you would see at a major Euro car show. The proportions are balanced perfectly from the front bumper to the rear valence.
We see a lot of matte black wheels on these Audis, which just kills the detail. This chrome finish forces you to look at the craftsmanship of the GMR hardware. It transforms the car from a sleeper into a head-turner.
Road presence is where this car really wins. The stance is aggressive but elegant, not over-the-top or gaudy. It looks like a factory prototype that Audi forgot to put into production.
I compare this to some of the cleanest B6 builds we have featured over the years. Most guys try too hard, but this owner kept it simple and executed it flawlessly. It proves that wheels can make or break the entire project.
Why We Love This Build
This S4 creates a moment every time the air compressor kicks on and the car settles onto the pavement. The way the chrome GMR barrels catch the sunset makes the whole build feel alive. It fills the arches with absolute precision and commands respect from everyone in the parking lot.
We love this car because it respects the heritage of the B6 while pushing the boundaries of fitment. It is a masterclass in how to pair a timeless wheel design with the right suspension setup. You do not just drive this car; you wear it like a tailored suit.
Go build something that makes people stop in their tracks just like this one does.

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 18×10 / 18×10-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 18×10 / 18×10-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
