About This Audi S4 Base 2013 Build
We love featuring real builds from real owners. This Audi S4 Base 2013 sits on a set of 20×10 / 20×10-inch Rosso Legacy wheels, and the result speaks for itself.
The owner chose Rosso for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of Audi S4 Base builds come through WheelFront every month, but this one stands out. The combination of the exterior with the Rosso Legacy creates a look that balances aggression with elegance.
Fitment Breakdown: Rosso Legacy on the Audi S4 Base 2013
I walked around this 2013 Audi S4 at the show and the Rosso Legacy wheels caught my eye immediately. Running a 20x10 square setup on a B8.5 chassis is a bold move. Most guys play it safe with 19s, but these 20s really fill out the wheel wells.
The +40 offset sits pretty flush with the factory fenders. You get a nice, aggressive stance without looking like a drift car. The 10-inch width pushes the wheel out just enough to kill that sunken stock look.
Clearing those big front calipers is always the biggest headache on an Audi. The spoke design on the Legacy offers plenty of concave clearance for the S4 brakes. I didn't see any sign of rubbing against the calipers during my inspection.
Since the car runs stock suspension, you have a bit of a gap, but the 20-inch diameter hides it well. You aren't tucked, but you aren't fighting wheel gap as much as you would with smaller rollers. It keeps the car looking purposeful.
The hub bore on these fits the Audi platform perfectly without needing messy hub rings. Everything centers up tight and runs smooth at highway speeds. A clean install makes all the difference in long-term reliability.
The barrel depth on these 10-inch wide wheels adds a ton of visual weight. It gives the car a grounded, planted aesthetic from every angle. You get that deep, industrial look that suits the sharp lines of the B8.5 perfectly.
Watch out for tight cornering and full-lock turns, though. With a 20x10 setup, you are pushing the limits of the factory fender liner. Just be mindful of steep driveways until you decide to drop the car on coilovers.
What We Recommend for Audi S4 Base 2013 Owners
If you want this look, stick to the 20x10 square setup like this build. It keeps tire rotations simple and maintains the neutral handling balance Audi designed into the car. Avoid going staggered unless you want to mess with your center diff.
Offsets between +35 and +40 are your sweet spot for this chassis. Anything lower than +35 will poke too much and spray rocks all over your paint. Stick to the +40 range to keep things flush and clean.
Don't be afraid to run a slightly stretched tire to clear the fender liners. A 255 or 265 width tire provides a nice look without sacrificing too much grip. It keeps the sidewall tidy and prevents rubbing during hard cornering.
We see a lot of guys make the mistake of using cheap spacers to force a fitment. If you pick the right offset, like these Rosso Legacy wheels, you don't need spacers at all. Keep your hubs clean and avoid the vibration issues that cheap spacers cause.
Check your fender liner screws if you plan on going lower later. A quick "fender screw mod" gives you a few extra millimeters of clearance. It is a cheap insurance policy for your tires.
Style and Build Analysis
The Black finish on these Rosso Legacy wheels creates a killer contrast against the factory paint. It adds a sinister, dark vibe that transforms the S4 from a executive cruiser into a street bruiser. The depth of the black paint hides brake dust well, too.
The spoke pattern is aggressive but stays true to the Audi design language. It doesn't look out of place or too "aftermarket" for the German engineering. It looks like a factory performance package that Audi forgot to offer.
Proportions matter more than anything else when you build a car. These 20s make the car look longer and lower even without touching the suspension. It creates a weighted, solid look that screams performance.
Compared to other builds I have seen, this one keeps the spirit of the B8.5 alive. It is refined, dark, and menacing without being over the top. You don't need a massive wing to stand out in a crowd.
This car holds its own next to much more expensive builds. It proves that a great set of wheels is the single best upgrade you can make. It changes the entire character of the vehicle instantly.
Why We Love This Build
I love this S4 because it looks like a daily driver that means business. The black wheels catch the sunlight and hide the hardware, letting the shape of the spokes do the talking. It sits with a level of confidence that makes you stop and stare every single time you walk past it.
This is how you modify an Audi without losing the class that makes it great. It is clean, functional, and undeniably aggressive. You feel the presence of the car before you even see it rolling down the street.
If you want to turn your boring commute into an event, this is the blueprint. Put some black Rosso Legacy wheels on your S4 and drive it like you mean it. It is the ultimate way to level up your game.

Before You Buy: Fitment Checklist
We talk to Audi S4 Base owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 20×10 / 20×10-inch wheels fit my Audi S4 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 S4 Base owners run 20×10 / 20×10-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
