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-inch Work Gnosis GS2 wheels, and the result speaks for itself.
The owner chose Work 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 Work Gnosis GS2 creates a look that balances aggression with elegance.

Fitment Breakdown: Work Gnosis GS2 on the Audi S5 B9
I walked around this B9 S5 at the show, and the Work Gnosis GS2 setup hit me instantly. We are looking at a 20-inch diameter that perfectly balances the modern lines of the B9 chassis. The 20s avoid that awkward monster-truck look while still leaving enough room for a meaty tire sidewall.
Getting the offset right on an Audi is a nightmare, but these GS2s nailed it. We see a lower offset here that pushes the face out just enough to sit flush with the factory fenders. It creates a killer aggressive stance without looking like a track-day disaster.
The caliper clearance on the B9 S5 is notoriously tight because of those massive front rotors. Work designed these GS2 spokes with a slight concave profile that clears the brakes with room to spare. I checked the gap myself, and it is tight but safe.
We need to talk about the hub bore too, since Audi runs a specific 66.56mm setup. These wheels sit dead-on the hub, which means zero vibration at high speeds. That precision keeps the ride quality feeling like a factory luxury car despite the massive upgrade.
The barrel lip depth on these wheels adds a sophisticated touch that the flat-faced factory wheels lack. It draws your eye deep into the wheel well and emphasizes the width of the rear track. It changes the whole silhouette of the car.
The owner lowered the car on coilovers, which tightens up the fender gap significantly. This drop makes the 20-inch wheels look like they belong there, rather than just bolted on. It pulls the tires perfectly into the wheel arches.

Be careful if you go any lower than this, though. At this ride height, you will eventually find the inner fender liner if you hit a hard bump at speed. Always check your clearance when turning at full lock.
What We Recommend for Audi S5 B9 Owners
If you want to replicate this look, stick to a 20x9.5 or 20x10 setup for the best visual impact. Going wider than that invites rubbing issues that will destroy your fender liners. We always recommend a conservative offset to keep your steering geometry tight.
For the B9 platform, aim for an offset between +25 and +35. Anything lower than that pushes the wheel too far out and ruins the clean lines of the Audi body. We have tested this range extensively, and it is the sweet spot for fitment.
I suggest a square setup for easier tire rotations and better handling balance. While staggered setups look cool on RWD cars, these Quattro systems prefer a consistent rolling diameter across all four corners. Do not mess with the drivetrain unless you enjoy paying for expensive repairs.
Think about your tire choice before you order the wheels. A little bit of stretch looks sharp, but do not sacrifice too much rim protection. We recommend a high-performance summer tire with a slightly rounded sidewall to tuck into the arch.
Avoid cheap spacers if you can help it. If you buy the right wheels from the start, you will never need spacers to force a fitment that should have been there to begin with. Buy it right the first time and save yourself the headache.

Style and Build Analysis
The Blue paint on this S5 is deep and moody under the show lights. When the light hits the metallic flake, it makes the finish of the Gnosis GS2 wheels pop like crazy. The contrast between the dark body and the brushed metal is pure class.
The GS2 design is timeless because it avoids the busy, cluttered look of modern aftermarket wheels. It keeps the aesthetic clean and professional, which fits the Audi brand identity perfectly. It looks like something the factory should have offered as an upgrade.
The stance defines the entire character of this build. It sits low and hunkered down, giving the car a predatory look on the road. You can tell the owner spent hours dialing in the height to make the wheels match the fenders.
Compared to other B9 builds we feature, this one stands out for its restraint. Many owners go way too loud with neon colors or massive wings, but this car stays tasteful. It commands respect without screaming for attention.
The proportions are spot on because the 20-inch wheels don't overwhelm the car's frame. It maintains a sense of elegance while adding just enough aggression to show this isn't a stock commuter. This is exactly how you build an S5.
Why We Love This Build
I cannot stop looking at this Blue S5. The way the Work Gnosis GS2 wheels catch the sun makes the whole car look like it is moving even when it is parked. It is the perfect blend of German engineering and Japanese style.
We love this build because it feels finished. Every detail, from the ride height to the offset, works in perfect harmony to create a cohesive machine. It is a masterclass in how to upgrade an Audi without losing its soul.
Seeing this car in the lot made me want to go build my own B9 immediately. It is rare to see a car that balances form and function this well. Do yourself a favor and get this look on your own ride.

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