About This Audi S4 2018 Build
We love featuring real builds from real owners. This Audi S4 2018 sits on a set of 17″, 18″, 19″, 20″, 21″ / 17″, 18″, 19″, 20″, 21″-inch TSW BATHURST wheels, and the result speaks for itself.
The owner chose TSW 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 exterior with the TSW BATHURST creates a look that balances aggression with elegance.
Fitment Breakdown: TSW BATHURST on the Audi S4 2018
I walked around this B9 S4 at the show yesterday and the TSW Bathurst setup stopped me cold. These wheels nail the aggressive look this platform craves without ruining the daily drive. The rotary forged construction keeps the unsprung weight low, which helps the S4 dance through corners.
We saw this specific build running an 18x9.5 setup that fills the wheel wells perfectly. The offset sits right at the edge of the fender line to give it a flush, muscular stance. You get that wide-track look without needing to pull the fenders or hack up your wheel arches.
The Bathurst features a dual-spoke design that creates tons of space for the massive factory calipers. I checked the clearance and you have plenty of room to spare, so you won't need sketchy spacers. The hub bore matches up perfectly, meaning no vibration issues at high speed.
The barrel lip depth on these wheels adds a nice level of visual intensity. It gives the car a deep, weighted look that makes the Audi feel more planted. Those spokes extend all the way to the rim edge, which makes the whole package look larger than it is.
If you drop the car on coilovers, you need to watch your alignment settings. You will rub the fender liners if you go too low without enough negative camber. A sensible drop keeps the geometry tight and prevents the tires from eating your plastic liners.
I suggest keeping an eye on the front inner clearance when you run this width. The stock suspension arms leave just enough room, but aftermarket components might change the math. Always test fit these before you commit to your final tire size.
Overall, this fitment choice shows the owner did their homework. It balances form and function in a way that makes the B9 look like it should have left the factory this way. It is a masterclass in clean, effective wheel selection.
What We Recommend for Audi S4 2018 Owners
If you want this look, stick to an 18-inch or 19-inch diameter. The 19s fill the arches better if you keep the factory ride height. The 18s offer a better ride and more tire sidewall if you live in a city with rough roads.
Aim for an offset between ET35 and ET42 for the best results. Anything lower than ET35 will poke too far and cause rubbing under hard compression. We love the ET40 mark for a truly flush, factory-plus aesthetic on this chassis.
Run a square setup to keep the handling predictable and neutral. Staggered setups on the S4 cause headaches with the Quattro system and uneven tire wear. Keep your tires the same size at all four corners to save your center differential.
Avoid excessive tire stretch if you actually drive your car hard. We prefer a meatier tire profile that protects the rim and offers better grip. A 255/35/19 tire works perfectly with the Bathurst wheel width on this specific Audi.
Don't fall for the trap of buying cheap spacers to fix poor wheel choices. Get the right offset from the start and avoid the extra failure point. Do it once, do it right, and keep your hub bolts happy.
Style and Build Analysis
The Bathurst design brings a sophisticated, racing-inspired edge to the Audi's clean lines. Its thin, tapered spokes draw the eye toward the center of the wheel. It looks purposeful and fast even when the car sits completely still.
The finish on this build contrasts perfectly against the factory paint. It adds a layer of metallic depth that really pops under the streetlights. We love how the darker shade hides brake dust while still highlighting the intricate spoke geometry.
Proportionally, this build is spot on for the B9 generation. It avoids the oversized, cartoonish look that ruins so many modern builds. The car looks like a serious sports sedan rather than a mall cruiser.
When you compare this to other builds, it stands out because of its restraint. It doesn't scream for attention with neon colors or massive lips. It relies on high-quality design to make a statement that lasts.
The stance gives the car a sense of gravity, pulling it closer to the tarmac. Every angle reveals a new detail in how the light hits the recessed center sections. This is how you modify an S4 with class and intent.
Why We Love This Build
This S4 captures the heart of what we love about the car scene. The way the sun hits the metallic finish on those TSW Bathurst wheels creates a gorgeous glow that makes the fenders look wider. You can tell the owner treats this car like a prized athlete, not just a grocery getter.
When this Audi rolls down the street, the wheels look like they belong in a motion blur. Everything flows together, from the sharp body lines to the precise fitment inside the arches. It stops us in our tracks because it looks like pure, unfiltered performance.
We want this look for our own daily drivers because it never gets old. It inspires us to keep pushing the boundaries of what a clean, tasteful build can achieve. Go get your set and transform your drive today.

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 17″, 18″, 19″, 20″, 21″ / 17″, 18″, 19″, 20″, 21″-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 17″, 18″, 19″, 20″, 21″ / 17″, 18″, 19″, 20″, 21″-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
