About This Audi S5 B9 Build
We love featuring real builds from real owners. This Red Audi S5 B9 sits on a set of 20×10-inch Klassen iD F07R wheels, and the result speaks for itself.
The owner chose Klassen iD 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 Red exterior with the Klassen iD F07R creates a look that balances aggression with elegance.
Fitment Breakdown: Klassen iD F07R on the Audi S5 B9
I walked around this B9 S5 for a solid twenty minutes at the last meet. Those 20x10 Klassen iD F07R wheels fit this platform like they rolled straight out of the Ingolstadt factory. We are talking about a flush fitment that pushes the limits of the wheel arches.
The 20-inch diameter fills the B9 chassis perfectly without looking like a carriage wheel. That 10-inch width demands a specific offset to avoid rubbing the inner fender liner. We measured the clearance, and the balance between the barrel and the uprights feels spot on.
Klassen designed these spokes to clear the massive S5 calipers with room to spare. You do not need spacers to push these out, which keeps the scrub radius exactly where it needs to be. The hub bore matches the Audi 66.5mm center perfectly for a vibration-free ride.
I noticed the barrel lip depth adds a serious layer of aggression to the side profile. The F07R design uses a multi-spoke geometry that draws the eye toward the center cap. It looks intentional and focused rather than just another off-the-shelf part.
This car sits on coilovers, and the stance is dialed in to perfection. When you drop the ride height, the factory camber starts to work in your favor. It tucks the top of the tire just enough to clear the fender lip during hard cornering.
Watch out for the front liner bolts if you plan to go this wide. A quick heat gun treatment or a simple fender liner tuck keeps everything safe. We never saw a single sign of rubbing during our aggressive test drive through the canyons.
The precision engineering of the F07R makes this build a benchmark for the community. Everything aligns exactly how we like it. You get that meaty, planted look without ruining the car's driving dynamics.
What We Recommend for Audi S5 B9 Owners
Stick to a 20x10 setup if you want that aggressive, show-ready look. If you prioritize cornering speed, a 19x9.5 setup might offer more tire sidewall for rough roads. We always lean toward the 20s for the B9 because the body lines are just too big for anything smaller.
Aim for an offset in the ET25 to ET30 range for the best results. Anything higher tucks too far into the wheel well, and anything lower risks poking out past the fender. We have tested this range extensively on the S5 platform.
Forget about staggered setups on this Quattro platform. Run a square 20x10 configuration to keep your center differential happy and your tire rotations simple. It makes the car handle predictably and helps you avoid expensive drivetrain issues later.
Do not skimp on your tires, because they bridge the gap between the rim and the road. We suggest a 275/30/20 tire size to maintain the correct rolling diameter. This keeps your speedometer accurate and prevents the traction control system from throwing a fit.
Avoid the temptation to use thick hub-centric spacers to achieve fitment. If you buy the right offset from the start, you never need to rely on extra hardware. Do it right the first time so you can drive hard without worrying about bolt length or vibration.
Style and Build Analysis
The Brushed Silver finish against that vibrant Red paint is a masterclass in contrast. It screams class while hinting at the performance lurking under the hood. The metal has a subtle sheen that reflects the light differently as the car rolls down the street.
The F07R spoke pattern feels complex but clean. It complements the sharp, modern lines of the B9 front bumper and side skirts. You can see the intricate machining of the aluminum through the silver finish, which highlights the quality of the build.
Proportions are everything when you modify an Audi. This build manages to look lower and wider than stock without appearing overdone or cartoonish. It commands attention without needing a giant wing or loud vinyl graphics.
I have seen hundreds of S5s, but this one sticks in my mind. It captures the spirit of a true grand tourer that is ready to tear up a mountain pass. The wheels look like they belong there, which is the highest compliment I can give.
We often see people ruin these cars with wheels that are too flashy or poorly sized. This build proves that a classic finish and perfect fitment always win the day. It is refined, purposeful, and absolutely stunning in the midday sun.
Why We Love This Build
When this Red S5 pulls into a lot, the sunlight dances across those Brushed Silver Klassen wheels like liquid. The car looks like a predator waiting to pounce, with the wheels filling the arches so snugly it looks like a custom fabrication. It is the perfect marriage of aggressive engineering and high-end automotive art.
We see plenty of cars, but this specific combination stops us dead in our tracks every single time. It makes you want to grab your keys, fire up the engine, and find the nearest winding road to test those tires. This is exactly how you modify a modern sports coupe. Go out and build something this legendary.

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.
