About This Audi S4 B9 Build
We love featuring real builds from real owners. This Blue Audi S4 B9 sits on a set of 20×9-inch Neuspeed RSf72 wheels, and the result speaks for itself.
The owner chose Neuspeed 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 builds come through WheelFront every month, but this one stands out. The combination of the Blue exterior with the Neuspeed RSf72 creates a look that balances aggression with elegance.
Fitment Breakdown: Neuspeed RSf72 on the Audi S4 B9
I walked around this B9 S4 for ten minutes straight at the meet. The Neuspeed RSf72 wheels in a 20x9 ET35 spec fit this chassis like they were engineered in Ingolstadt. That offset pushes the face out perfectly to the fender line without any of that awkward poke.
The B9 platform is notoriously picky about wheel specs. Most guys mess up the hub bore or caliper clearance, but this setup avoids those headaches entirely. These wheels are hub-centric for the Audi, so you get zero vibration at highway speeds.
The 034 lowering springs drop the car just enough to kill the wheel gap. It sits low enough to look aggressive but keeps the geometry tight. You get that clean, slammed look without sacrificing the suspension travel you actually need for daily driving.
We checked the inner clearance near the upper control arm bolt. Even with the 265/30/20 tires, there is just enough room to breathe. You won't find any rubbing here, even under hard cornering or heavy compression.
The spoke design on the RSf72 flows really well with the sharp lines of the B9 body. Those spokes clear the massive S4 front calipers with room to spare. You don't need a spacer, which keeps the scrub radius exactly where the engineers intended.
The barrel depth is surprisingly generous for a flow-formed wheel. It gives the rim a concave profile that makes the car look wider than stock. It is a subtle detail that separates a good build from a great one.
I recommend keeping an eye on the front fender liners if you plan to go any lower than this. The 265 tire is meaty for this offset, but it works perfectly with the current ride height. This is the definition of a dialed-in fitment.
What We Recommend for Audi S4 B9 Owners
If you want to replicate this, stick to a 9-inch wide wheel. Anything wider than 9.5 inches will force you into aggressive offsets that ruin your steering feel. Keep your ET between 32 and 35 for that flush look.
Don't bother with staggered setups on this platform. The Quattro system hates different rolling diameters, and you want to be able to rotate your tires. A square 265/30/20 setup is the gold standard for performance and aesthetics.
The 265 tire offers a nice, square sidewall profile. It protects the wheel lip from potholes and curb rash while filling the arch nicely. If you go too skinny, you get that stretched look that just doesn't belong on a sophisticated German sedan.
Many guys make the mistake of buying cheap, heavy cast wheels. The RSf72 uses flow-forming tech to shave weight where it matters most. Reducing unsprung mass makes a massive difference in how the S4 handles bumps.
Avoid cheap spacers if you can help it. If you choose the right offset from the start, you never need to mess with them. Proper hub-centric rings are mandatory if you aren't running a direct-fit wheel like this.
Style and Build Analysis
The blue paint on this S4 is deep, vibrant, and incredibly moody. When you pair that with the Gloss Bronze Neuspeed finish, the car pops instantly. Bronze on blue is a classic rally-inspired color combo that never goes out of style.
The RSf72 spokes are thin enough to show off the braking system but aggressive enough to draw the eye. They look like they are constantly moving, even when the car is parked. The gloss clear coat makes the bronze shift from dark chocolate to bright penny in the sunlight.
The proportions on this car are spot on. It doesn't look like a circus act or a tuner project gone wrong. It looks like a high-performance executive machine that means business on a canyon road.
I have seen dozens of B9s with different wheel brands, but this stands out. Most people choose black wheels, which just disappear into the tire. This bronze finish gives the car a custom, high-end identity that demands attention.
The stance is low, tight, and purposeful. It hits that sweet spot between a track-ready weapon and a comfortable street cruiser. Everything about this build feels intentional and refined.
Why We Love This Build
I cannot stop looking at how this blue paint catches the light against those bronze wheels. The RSf72s fill the wheel arches so perfectly that the car looks like it was molded as one single piece. It is the kind of build that makes you look back every single time you walk away.
This car proves that you do not need over-the-top aero or wild modifications to win the show. You just need the right drop, the right offset, and a finish that complements the body. It is clean, fast, and undeniably cool.
When this Audi rolls down the street, the wheels catch the sun and the car looks like a predator. This is exactly how an S4 should sit. Stop dreaming and get your fitment sorted.

Before You Buy: Fitment Checklist
We talk to Audi S4 owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 20×9-inch wheels fit my Audi S4? 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 owners run 20×9-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
