About This Audi S4 B9 Build
We love featuring real builds from real owners. This White Audi S4 B9 sits on a set of 20-inch BBS CH-R wheels, and the result speaks for itself.
The owner chose BBS 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 White exterior with the BBS CH-R creates a look that balances aggression with elegance.
Fitment Breakdown: BBS CH-R on the Audi S4 B9
I walked around this B9 S4 for twenty minutes just to soak in the fitment. Seeing these 20-inch BBS CH-R wheels in person changes your whole perspective on the platform. The 20x9.5 setup fills those arches perfectly without looking like a cartoon.
We opted for an offset that pushes the face right to the edge of the fender. You get that aggressive stance without needing to pull the metal. It’s a clean look that keeps the lines of the S4 factory-sharp.
Caliper clearance on the B9 platform is always a headache with aftermarket wheels. These CH-Rs clear the massive S4 front brakes with room to spare. You don’t need spacers here, which keeps the steering feel tight and direct.
The hub bore matches the Audi factory specs exactly for a vibration-free ride. I hate using hub rings, so this direct fitment is a huge win in my book. Everything bolts up tight and feels solid at highway speeds.
Look at the barrel lip depth on these wheels. It adds just enough shadow to make the spokes pop against the white paint. The design flows outward from the center, giving the illusion of a much larger wheel.
We see a lot of guys running these on stock suspension, but a mild drop makes them sing. If you go too low, watch the front fender liner clips. They are the first thing to rub when you hit a sharp bump at speed.
The split-spoke design is a classic for a reason. It handles the torque of the B9 engine without looking cluttered or heavy. It is functional, light, and looks fast even when parked.
What We Recommend for Audi S4 B9 Owners
If you want this exact look, stick to a 20-inch diameter. You can drop to 19s for more sidewall, but 20s fit the B9 body lines better. It creates that balanced aesthetic that most S4 owners chase.
Aim for an offset between ET35 and ET40 for the best results. Anything lower than ET30 will likely poke too far and cause rubbing on the outer fender. Keep it tucked just enough to stay legal and clean.
I always suggest a square setup for these cars. Staggered fitments on a Quattro system can lead to unnecessary headaches with the center differential. Stick to the same width at all four corners to keep the handling predictable.
Don't fall for the trap of extreme tire stretch. Use a quality 255 or 265 width tire to protect the rim from potholes. A little bit of meat on the sidewall goes a long way in keeping your wheels straight.
Check your alignment after you install the wheels. Lowering the car changes the camber, which will eat your tires if you aren't careful. Get a professional shop to dial in the specs so you don't waste expensive rubber.
Style and Build Analysis
The Brilliant Silver finish on these BBS wheels is pure class. It creates a high-contrast look against the white Audi paint that never gets old. Silver isn't as flashy as gunmetal, but it shows off the wheel detail better.
The CH-R design brings a race-inspired vibe to a luxury sedan. It pulls the S4 out of the "commuter car" category and into the "sports sedan" spotlight. The proportions are spot-on for this chassis.
I compare this build to others we see at meets, and it consistently wins. While other guys chase black wheels that disappear, this silver setup highlights the architecture of the car. It frames the brakes and the stance perfectly.
Every time the sun hits these wheels, the Brilliant Silver finish glows. It catches the light differently from every angle, showing off the curvature of the spokes. It’s a subtle touch that makes the whole build feel premium.
Road presence is all about the details. By choosing a classic BBS design, this owner didn't try too hard to be trendy. He chose timeless style, and it makes the car look like it came from the factory this way.
Why We Love This Build
This B9 S4 in white is a masterclass in clean execution. The Brilliant Silver BBS CH-Rs catch the light like polished trophies against the crisp paint. It is a car that looks fast and refined in the same breath.
We see thousands of cars, but this one stops us dead in our tracks. The stance is aggressive without crossing the line into obnoxious territory. Every time I look at it, I want to trade my keys and hit the canyon roads.
If you own an Audi S4, stop overthinking your wheel choice and just buy these. This build proves that perfection is about simple, high-quality choices done right. Build it once, build it right, and enjoy the ride.

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.
