About This Audi S4 B9 Build
We love featuring real builds from real owners. This Black Audi S4 B9 sits on a set of 19×9.5-inch Rays TE37 Ultra wheels, and the result speaks for itself.
The owner chose Rays 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 Black exterior with the Rays TE37 Ultra creates a look that balances aggression with elegance.
Fitment Breakdown: Rays TE37 Ultra on the Audi S4 B9
I walked around this B9 S4 for twenty minutes just to soak in the stance. The 19x9.5 setup fills those wheel wells perfectly without looking like a desperate cry for attention. That ET35 offset pushes the face out right to the edge of the fender line.
We see a lot of guys struggle with brake clearance on these Audi platforms. The TE37 Ultra has that concave spoke design which swallows the factory S4 calipers whole. You get plenty of room to breathe even if you decide to upgrade to a massive big brake kit later.
The 9.5-inch width is the absolute sweet spot for the B9 chassis. It provides a wide enough footprint to actually put the power down to the pavement. You get a nice, meaty tire patch without turning the front end into a tramlining mess on the highway.
I checked the hub bore compatibility while I was there. These Rays wheels fit the Audi 66.5mm hub perfectly with the right rings. You avoid those nasty steering wheel vibrations that plague guys running cheap, universal-fit wheels.
The barrel design on the Ultra is a masterpiece of engineering. It keeps the unsprung weight low while maintaining structural rigidity for hard cornering. You feel the difference in the steering feedback the second you roll out of the driveway.
Lowering springs or a proper coilover setup really changes the game here. Even with a drop, the ET35 offset keeps you clear of the fender liners. You might get a slight rub on the plastic liner if you slam it to the dirt, but that is the price of admission for this look.
This fitment is aggressive but stays functional. It hits that mark between track-day weapon and daily-driven street car. I love that it does not require a body shop to make it fit right.
What We Recommend for Audi S4 B9 Owners
Do not go wider than 9.5 inches if you actually like how your car handles. Anything beyond that creates massive headaches with tire rub and steering geometry. Stick to the proven math to keep your suspension happy.
I always suggest a square setup for the B9. You want to be able to rotate your tires to get the most life out of your rubber. Staggered setups on these cars look cool, but they destroy the Quattro system's balance.
Pick your tires carefully to match this 19-inch setup. A 255/35/19 tire works beautifully with this 9.5-inch width. You get a slight bit of sidewall protection without looking like a tuner kid from a 2005 movie.
Avoid spacers if you can possibly help it. We have tested this ET35 setup, and it does not need any extra hardware to look flush. Every spacer you add just introduces another point of failure for your wheel bearings.
Common mistakes usually involve buying the wrong offset and trying to fix it with cheap adapters. Don't be that guy. Buy the right wheel the first time and save your money for good alignment settings instead.
Style and Build Analysis
The contrast here is just violent in the best way possible. That deep, matte Bronze finish pops against the aggressive Black paint. It creates a sinister aesthetic that commands respect the moment the car rolls into the light.
The TE37 is an icon for a reason. Its six-spoke design is timeless and adds a touch of motorsport heritage to the otherwise smooth B9 body lines. It looks like it belongs on a mountain pass or a circuit lap.
Proportion is everything when you modify a car like the S4. The 19-inch diameter maintains a sophisticated profile while the wide stance screams performance. It does not look cartoonish; it looks purposeful and mean.
I have seen dozens of B9s running generic black wheels, but they all fade into the background. This Bronze setup forces your eyes to lock onto the wheels. It highlights the engineering beneath the fenders rather than hiding it in shadow.
The car sits with a sense of gravity that most stock S4s lack. Every angle of the wheel design draws the eye toward the center cap. It elevates the entire aesthetic of the Audi platform without crossing into gaudy territory.
Why We Love This Build
This car is the perfect mix of German engineering and Japanese style. Seeing that Black Audi hunkered down over the Bronze TE37s made me want to grab the keys and hit the canyon roads immediately. The way the metallic flakes in the paint dance under the spokes is pure automotive art.
This build stops us in our tracks because it is honest and aggressive. It does not hide behind flashy body kits or over-the-top modifications. It relies on perfect fitment and a legendary wheel design to do all the heavy lifting.
Stop overthinking your next set of wheels and just get these. This is the definition of a build done right.

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 19×9.5-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 19×9.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
