About This Audi S4 B8 Build
We love featuring real builds from real owners. This Blue Audi S4 B8 sits on a set of 20-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 Blue exterior with the TSW Bathurst creates a look that balances aggression with elegance.
Fitment Breakdown: TSW Bathurst on the Audi S4 B8
When I first walked around this B8 S4, the stance hit me instantly. We mounted these 20-inch TSW Bathurst wheels, and the proportions look perfect for the chassis. The 20-inch diameter fills the massive Audi arches without turning the car into a total monster truck.
The Bathurst features a rotary-forged construction that keeps the weight down significantly. This helps the B8 steering feel stay sharp even with the larger diameter. You get that lightweight performance while keeping the street-ready aesthetic.
We checked the brake clearance, and the Bathurst design clears those stock S4 calipers easily. You do not need massive spacers to force these wheels to fit over the iron brakes. The spokes curve outward just enough to keep the calipers from making contact.
The offset we chose sits flush with the fender line. You get a wide, aggressive track width that makes the car look planted. It eliminates that sucked-in look that plagues so many factory B8 setups.
Running a 20-inch wheel on this platform requires a solid suspension setup. We recommend a quality coilover kit to dial in the drop and tuck the tires properly. If you go too low, you might need to roll the fenders slightly to avoid rubbing on big bumps.
The hub bore on these TSW wheels is machined specifically for the Audi center bore. You get a vibration-free ride without messing around with flimsy plastic hub rings. Everything bolts up tight and stays centered at high speeds.
The deep barrel design adds a sense of depth that draws your eye toward the center cap. The split-spoke pattern gives the car a modern, technical vibe. It really emphasizes the mechanical nature of the B8 platform.
What We Recommend for Audi S4 B8 Owners
For the B8 platform, stick to a square setup to keep the handling predictable. Staggered setups often mess with the Quattro system's delicate torque split. We have tested both, and square is the only way to go for daily driving.
Target an offset in the ET35 to ET40 range for the cleanest look. This keeps the scrub radius within factory limits so your steering geometry stays intact. You want the wheels to push out, but you do not want to destroy your wheel bearings.
If you choose to run a 20-inch wheel, you must select the right tire profile. A 255/30/20 tire provides enough sidewall to protect your rims from brutal potholes. Do not go too thin, or you will bend a barrel on the first highway expansion joint you hit.
Avoid massive spacers if you can help it. A thin 3mm or 5mm spacer might help with fine-tuning the look, but thick spacers just add unnecessary stress to your hubs. Buy the right offset from the start and avoid the headache.
We see many owners make the mistake of choosing wheels that are too wide. An 8.5 or 9-inch width is the sweet spot for the S4. Anything wider will force you to run aggressive camber just to keep the tires under the sheet metal.
Style and Build Analysis
The Gloss Gunmetal finish on these wheels provides a stunning contrast against the blue paint. Blue and grey are a classic combination that never goes out of style. The dark wheels ground the car and make the paint look even deeper and more vibrant.
I love how the Gloss Gunmetal catches the light throughout the day. In direct sunlight, it shows off the complex spoke geometry of the Bathurst. When the sun goes down, the wheels sink into the shadows, giving the car a mean, stealthy look.
The TSW Bathurst design looks fast even when the car sits parked. The slim, refined spokes mimic the sharp lines of the Audi bodywork perfectly. It feels like an extension of the factory design language, just turned up to eleven.
Compared to other builds we have featured, this one strikes the perfect balance. It avoids the over-the-top, gaudy modifications that ruin the S4's clean lines. It looks like a high-end factory concept car that finally made it to the street.
This car commands attention without screaming for it. You notice the wheel fitment first, then you realize how well the finish complements the blue wrap. It is a masterclass in tasteful, performance-oriented modifications.
Why We Love This Build
This B8 S4 is exactly what a daily-driven street machine should look like. The way that blue paint pops against the dark, gunmetal finish is pure automotive art. We stood back and just stared at how the 20-inch wheels filled those arches perfectly. The car looks like it wants to hunt down every apex on the way to the office.
Every time this car pulls into a meet, it draws a crowd instantly. It has that rare quality of being both aggressive and incredibly sophisticated. We love this build because it does not compromise on performance to achieve its stunning aesthetic. If you want to transform your S4, this is the blueprint you follow. Pure perfection.

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.
