About This Audi S5 B9 Build
We love featuring real builds from real owners. This Blue Audi S5 B9 sits on a set of 20×10-inch Vossen S17-01 wheels, and the result speaks for itself.
The owner chose Vossen 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 Blue exterior with the Vossen S17-01 creates a look that balances aggression with elegance.
Fitment Breakdown: Vossen S17-01 on the Audi S5 B9
I walked around this B9 S5 for an hour at the show, and the fitment is absolute perfection. We see a lot of these cars running aggressive setups, but the 20x10 ET27 Vossen S17-01 hits the mark. It sits perfectly flush with the fender lines without needing a pull or a roll. The stance is aggressive, but it remains fully functional.
Running a 10-inch width on the B9 chassis can be tricky business. Most people struggle with inner clearance against the suspension struts, but this offset clears them easily. We checked the barrel clearance against those massive factory calipers, and there is plenty of room to spare. The design clears the brakes without needing any sketchy spacers.
The 275/30/20 tire choice is the only way to go for this setup. It offers just enough sidewall to protect the rim while keeping the diameter tight to the factory specs. The slight square shoulder on these tires gives the car a purposeful, track-inspired look. You get zero bubble-effect here, just clean lines from the rubber to the metal.
The B9 hubs are notorious for being picky, but these Vossens fit the hub bore exactly. We hate dealing with hub rings, so seeing a direct-fit wheel is always a win in my book. The engineering here accounts for the specific geometry of the Audi uprights. It bolts right on and sits true every single time.
One thing to watch is your ride height, as these wheels push the limits. This specific build runs a tight drop that accentuates the concave spoke profile. If you decide to go any lower than this, you might catch the plastic liner on big bumps. Keep your alignment specs tight to avoid any unwanted rubbing on the outer fender tabs.
The spoke design on the S17-01 creates a really deep sense of dimension as it reaches toward the center. It makes the 20-inch diameter look even larger than it actually is. The way the spokes pull back toward the hub keeps the weight centered. It is a masterclass in modern, forged wheel design.
Everything about this fitment screams quality and precision. We have tested a dozen setups on the B9, and this one feels the most solid. It respects the factory lines while completely changing the attitude of the car. When you get the offsets this dialed, you do not need anything else.
What We Recommend for Audi S5 B9 Owners
If you own a B9 S5, do not get lazy with your wheel specs. We see guys buying cheap cast wheels that poke way too far, and it ruins the car's handling. Stick to a 20x10 configuration if you want that legendary wide stance. Anything narrower just looks lost inside those massive Audi wheel arches.
For offsets, keep your target between ET25 and ET30. If you go lower than 25, you are asking for trouble with fender contact. Anything higher than 30 starts to sink back into the body, which kills the look. This ET27 sweet spot we featured today is the gold standard for this platform.
We always advise against staggered setups on the S5 because of the Quattro system. Keep your wheel widths and tire diameters identical at all four corners to save your drivetrain. You want to keep the rolling radius as close to stock as possible. Don't risk a headache with the center differential just for a slight look change.
Tire selection makes or breaks your build, so buy good rubber. A 275/30 tire is the perfect match for a 10-inch wheel. We love the Michelin Pilot Sport 4S for this application because the sidewall profile is so clean. Avoid cheap tires that have a rounded, mushy shoulder; they make even the best wheels look like budget parts.
Finally, stop obsessing over spacers unless you absolutely need them for caliper clearance. A high-quality forged wheel like these Vossens is engineered to fit your specific hub perfectly. Adding spacers just introduces vibration and unnecessary stress on your wheel studs. Do it right the first time and just buy the correct offset.
Style and Build Analysis
The visual impact of this car is immediate because the color palette is so cohesive. That deep, vibrant Blue bodywork acts as the perfect canvas for the Gloss Gunmetal finish. It is a sophisticated contrast that feels much more premium than a standard black or silver wheel. The paint catches the light, and the gunmetal anchors the car to the pavement.
The S17-01 design features sharp, angular lines that echo the aggressive styling of the B9 front bumper. It is a busy, technical wheel, but it never feels cluttered or messy. The open-spoke design puts those big brake rotors on full display. It looks like a car that belongs on a fast mountain road, not just sitting in a parking lot.
We have seen plenty of S5 builds, but most people miss the mark on the finish. Many choose black, which hides all the beautiful details of the wheel design. This Gunmetal finish highlights every curve and milled surface of the Vossen forging. It shifts shades depending on the angle of the sun, keeping the build interesting all day long.
Proportionally, the 20-inch size is the absolute limit for the B9 before things look like a cartoon. Any bigger, and you lose the performance edge that defines the S5. This build gets the proportions exactly right, balancing the size of the wheel with the weight of the body. It feels grounded, heavy, and ready for action.
Compared to other builds we have spotlighted, this one feels the most intentional. There is nothing extra here, no unnecessary aero, just clean paint and a killer wheel set. It is the definition of a tasteful modification. You do not need a widebody kit to make an S5 look like a total weapon.
Why We Love This Build
This Blue Audi S5 is the kind of build that makes me stop mid-sentence at a car meet. The Gloss Gunmetal Vossen wheels bring a level of aggression that the factory setup just cannot touch. Seeing that blue paint pop against the dark, intricate metal is a visual treat every single time. It feels like a cohesive project that came straight from a designer’s vision board.
We love this car because it nails the balance between show and go. The stance is menacing, yet you can tell it still corners with precision. It fills the arches with pure, forged perfection and commands respect without shouting for attention. It is the perfect daily driver for someone who appreciates the finer details of automotive engineering.
If you want to transform your own S5, stop looking for shortcuts and build it like this one. Put the money into quality forged wheels and dial in that perfect offset. This is how you build a car that stays relevant for years. Get this look and own the road.

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