About This Audi S5 B9 Build
We love featuring real builds from real owners. This Black Audi S5 B9 sits on a set of 20×10.5-inch Brixton Forged RF10 wheels, and the result speaks for itself.
The owner chose Brixton Forged for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of Audi S5 builds come through WheelFront every month, but this one stands out. The combination of the Black exterior with the Brixton Forged RF10 creates a look that balances aggression with elegance.
Fitment Breakdown: Brixton Forged RF10 on the Audi S5 B9
I walked around this B9 S5 last week, and the stance is absolute perfection. Running a 20x10.5 setup on all four corners fills the wheel wells exactly how Audi engineers intended, just with way more attitude. That ET27 offset pushes the wheels right to the edge of the fenders without looking like a monster truck.
The Brixton Forged RF10 design clears the massive front calipers with room to spare. Many wheels struggle with this platform because of the stock brake geometry, but these clear the hardware easily. You won't need spacers here, which keeps the hub connection clean and strong.
The hub bore sits perfectly flush for that factory-style fitment. We hate dealing with hub rings, but these wheels bolt right onto the B9 hubs without any adapters. It makes the ride vibration-free at high speeds.
I looked closely at the inner barrel clearance near the suspension struts. Even with the 10.5-inch width, you get plenty of room so nothing rubs during hard cornering. You get maximum width without compromising the steering geometry.
The spoke design on the RF10 is sharp and aggressive. It creates a nice concave profile that draws your eye toward the center cap. The depth of that concave shape really defines the look of this specific build.
We saw this car running a lowered suspension, which really tightens up the fender gap. If you run this exact setup at stock height, you might want to consider some lowering springs to get that flush look. It ties the whole design together.
You have to watch your tire clearance on the inner liner during full lock. With 275-wide tires, you are right at the limit of what fits comfortably. It is a tight fit, but it definitely clears the plastics.
What We Recommend for Audi S5 B9 Owners
If you want this look, stick to the 20-inch diameter for the best visual balance. Anything smaller feels lost in the B9 arches, and 21s often ruin the ride quality. Keep it to 20s for the street.
For width, 10 inches is safe, but 10.5 inches is the sweet spot for a meaty stance. We see guys try to go wider, but you end up fighting rubbing issues constantly. Don't go wider than 10.5 if you want to drive the car hard.
Offset is the most critical part of this equation. For the B9, keep your offset between ET25 and ET30. Anything lower than ET25 and you will poke past the fenders, which looks messy and kicks rocks all over your paint.
Regarding tires, the 275/30/20 setup is the gold standard for this car. It provides enough sidewall to protect your rims from potholes while maintaining a flat, performance-oriented profile. It’s the perfect balance of form and function.
Avoid the temptation to use cheap spacers to force a fit. If you choose the right offset initially, you never have to worry about wheel studs or balance issues. Do it once and do it right with the correct offset wheels.
Style and Build Analysis
The monochromatic look on this S5 is pure aggression. By pairing Satin Black wheels with a Black car, the owner created a stealthy vibe that demands respect. The different textures between the paint and the satin finish keep it from looking like a flat blob.
The RF10 spokes have a crisp, machined quality that stands out against the dark bodywork. Light hits the edges of the spokes while the barrels fade into the shadows. It creates a dynamic look that changes depending on the time of day.
Proportions are everything on a B9 platform. This build sits low and wide, giving the car a planted, predatory stance. It doesn't look like a modified luxury coupe; it looks like a factory-built track weapon.
Compared to other builds we feature, this one avoids the over-the-top flashiness that ruins some Audi projects. There is a maturity to this aesthetic that stays true to the S5’s sophisticated lines. It proves that you don't need wild colors to make an impact.
The road presence of this car is intimidating. When you see it rolling down the street, the wheels look like they are spinning knives. It is a masterclass in how to upgrade a car without losing its soul.
Why We Love This Build
This Audi S5 hits differently because of the attention to detail. The Satin Black Brixton Forged wheels disappear into the tires at speed, then pop with texture when the car parks under the lights. It looks like a tuxedo on wheels.
The way those 20-inch barrels fill the arches makes the stock wheels look like toys. We love how the car hugs the ground without looking like a track-day disaster. It stays clean, classy, and utterly menacing.
Every time I look at these photos, I want to go grab my own B9 and replicate the exact same setup. It is the ultimate blueprint for a daily driver that looks ready for a magazine cover. Build it just like this and you will never regret it.

Before You Buy: Fitment Checklist
We talk to Audi S5 owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 20×10.5-inch wheels fit my Audi S5? 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 S5 owners run 20×10.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
