About This Audi S5 Base 2013 Build
We love featuring real builds from real owners. This Audi S5 Base 2013 sits on a set of 20×10.5 / 20×10.5-inch XO Phoenix wheels, and the result speaks for itself.
The owner chose XO 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 Base builds come through WheelFront every month, but this one stands out. The combination of the exterior with the XO Phoenix creates a look that balances aggression with elegance.
Fitment Breakdown: XO Phoenix on the Audi S5 Base 2013
I walked around this S5 at the show last week and the stance is absolutely spot on. We are looking at a square setup running 20x10.5 wheels at all four corners. That massive width gives this Audi a presence that the factory setup just lacks.
The 30 offset pushes the face of the wheel right out to the edge of the fender. It creates a flush look that most B8.5 owners only dream about achieving. We love how that extra width fills out the wheel wells perfectly.
The XO Phoenix design features a multi-spoke layout that clears the factory Audi calipers with room to spare. You do not need to worry about the barrel hitting the housing on these base brakes. It is a clean fit that looks custom without being reckless.
Because the car sits on air suspension, the fitment changes the second you hit the controller. When it airs out, the fenders tuck right over the top of the tire beads. It is a precise dance between the inner barrel and the control arms.
We checked the hub bore to ensure it matches the Audi 66.6mm requirement. Getting this right prevents any annoying vibrations at highway speeds. Trust me, you do not want to skimp on hub rings if you want a smooth ride.
The 10.5 width does mean you need to watch your inner clearance during turns. If you run too wide a tire, you might catch the plastic liner under full lock. We always recommend a slight stretch to keep the sidewall tucked inside the fender lip.
This car pulls off a aggressive poke when aired up, but it lays flat when parked. That transition is exactly why people build these cars on air. It turns a daily driver into a show-stopping piece of art.
What We Recommend for Audi S5 Base 2013 Owners
If you want this look, stick to the 20-inch diameter. Anything smaller gets lost in the massive arches of the B8.5 chassis. The 10.5 width is the absolute limit for a clean, flush fitment.
For offsets, keep that number between 25 and 30. If you go lower, you will definitely poke out past the fender and look like a drift car. If you go higher, you will need spacers just to get the wheels looking decent.
We always suggest a square setup for these Audis. It allows you to rotate your tires and keeps the Quattro system happy. Staggered setups on these cars can sometimes confuse the differential sensors.
Do not be afraid of a little tire stretch to make things fit. A 275/30/20 tire works wonders on a 10.5-inch rim. It gives you just enough protection for the rim edge while keeping the profile low.
Avoid buying cheap knock-off wheels that do not support the weight of the S5. This car is heavy, and you need a wheel that can handle the torque. The XO Phoenix is built well enough to take the abuse of daily driving.
Style and Build Analysis
The all-black finish on these XO Phoenix wheels completely changes the vibe of the S5. It makes the car look darker, meaner, and significantly more aggressive. Against the metallic paint, the wheels disappear into the shadow of the wheel well.
The spoke pattern on the Phoenix is intricate and sharp. It breaks up the smooth, rounded lines of the Audi bodywork perfectly. We think the geometric design offers a great contrast to the soft curves of the car.
Proportions are everything when you are building a B8.5. By running the same wheel size front and rear, the car looks balanced from every angle. It creates a sense of weight that makes the car look planted to the tarmac.
Compared to other S5s we have featured, this one is much more refined. It does not rely on crazy colors or massive wings to grab your attention. It uses high-quality parts to enhance the factory lines rather than hiding them.
You can see how the light hits the spokes when the car is in motion. The black finish hides brake dust better than silver, which is a huge plus for daily driving. This is a functional style choice that keeps the car looking clean after a long drive.
Why We Love This Build
This Audi S5 is the reason we fell in love with the modified car scene. Seeing the black XO Phoenix wheels tucked perfectly into those arches when the air suspension dumps is pure magic. The way the black finish absorbs the light makes the whole car look like it is carved from a solid block of granite.
It captures that perfect balance between luxury and aggression that every enthusiast chases. You know the owner put in the time to dial in the offset until it was absolutely perfect. It is the kind of build that makes you stop dead in your tracks at a crowded meet.
Grab your own set and bring that vision to life. This is the gold standard for a B8.5 stance.

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