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 Avant-Garde M540 wheels, and the result speaks for itself.
The owner chose Avant-Garde 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 Avant-Garde M540 creates a look that balances aggression with elegance.
Fitment Breakdown: Avant-Garde M540 on the Audi S4 Base 2013
I walked around this B8.5 S4 for a solid twenty minutes at the last show. Seeing the Avant-Garde M540s in a 20x10 square setup on this platform really hits different. That ET35 offset pushes the face out right to the edge of the fender line.
We see a lot of guys struggle with the B8 chassis, but this 20x10 fitment is spot on. You get a nice concave profile on the M540 spokes that standard 19-inch wheels just can’t replicate. It creates a bold, aggressive stance that demands attention.
The hub bore on these AG wheels matches the Audi 66.6 center bore perfectly. We didn’t need any sketchy hub rings to get these seated flush. That precision keeps the steering vibration-free even when you push it hard.
Clearance around those factory S4 calipers is surprisingly generous with the M540 design. Those spokes arc out enough to clear the massive rotors without needing spacers. I hate spacers, so seeing this direct bolt-on fitment made my day.
The air suspension setup is the real game-changer here. When the bags are fully aired out, the wheels tuck neatly inside the fenders without crushing the liners. It is the perfect marriage of form and function.
If you run this setup at a high ride height, watch out for the inner fender plastic. The wide 20x10 barrel can rub slightly on the front arch liners during full lock turns. Keep an eye on your hardware if you plan to drive low all the time.
The machined finish catches the light in a way that makes the barrel depth look infinite. It creates a sharp contrast against the curves of the Audi bodywork. This isn't just a wheel choice; it is a calculated visual upgrade.
What We Recommend for Audi S4 Base 2013 Owners
If you want to mirror this look, stick to the 20-inch diameter. Anything smaller gets swallowed up by the S4’s heavy body lines. A 10-inch width is the absolute maximum I would recommend for a clean daily setup.
Stay within the ET32 to ET35 range for your offsets. Anything lower than ET30 will have you poking way too far past the fender. We want that flush look, not a tractor-tire aesthetic that destroys your paint.
I always push for a square setup on these Quattro cars. Running the same 20x10 size on all four corners keeps your differential happy and your handling predictable. It also makes tire rotations much easier in the long run.
Don't get lazy with your tire choice on a 20x10 wheel. We recommend a slight stretch with a 255/30 or 265/30 tire to clear the fender lips. If you try to run a meaty 275, you will be trimming your liners every single weekend.
Most guys mess up by ignoring the alignment specs after installing air. Make sure you dial in a bit of negative camber to tuck those tops under the fender. Without that adjustment, you are just waiting for a sharp bump to shatter your fenders.
Style and Build Analysis
The Machined finish on these M540s provides a clean, premium aesthetic. It avoids the cheap look of polished chrome while offering more pop than basic silver paint. It perfectly complements the silver trim accents found on the B8.5 S4 mirrors and grille.
The M540 spoke design is a modern take on the classic mesh wheel. It feels purposeful and stiff, which mirrors the S4’s reputation for understated performance. It is a sophisticated choice that avoids the loud, tacky trends we see elsewhere.
When you look at the car in motion, the spokes create a hypnotic blur. The proportions are near perfect, filling the wheel wells with just the right amount of metal. It turns a standard executive sedan into something that looks like it belongs on a track.
Comparing this to other builds, the restraint shown here is what wins me over. Many owners go for wild colors or massive lips that ruin the Audi DNA. By sticking to the machined finish and a sensible offset, this owner let the S4’s natural design shine.
Road presence is everything with these cars. This build carries a certain weight and authority that makes people stop and stare in the parking lot. You can tell the owner understands that fitment is 90 percent of the battle.
Why We Love This Build
There is something magical about seeing this S4 aired out at the curb. The machined faces of the M540s catch the late afternoon sun, glowing against the dark paint of the Audi. The wheels fill the arches with military precision, leaving just enough room to show off the craftsmanship of the spokes. It looks like it was engineered by the factory for this exact stance.
We see hundreds of builds, but this one stops us dead in our tracks. It proves that you do not need over-the-top mods to build a show-stopper. It is the perfect balance of luxury, aggression, and clean, smart fitment. This is the gold standard for the B8.5 platform. Go get yours done.

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.
