About This Audi S4 B8 Build
We love featuring real builds from real owners. This Black Audi S4 B8 sits on a set of 20×10-inch Rohana RFX10 wheels, and the result speaks for itself.
The owner chose Rohana 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 Black exterior with the Rohana RFX10 creates a look that balances aggression with elegance.
Fitment Breakdown: Rohana RFX10 on the Audi S4 B8
I walked around this B8 S4 for twenty minutes just staring at the wheels. The Rohana RFX10 in 20x10 ET33 is an aggressive choice that defines the entire stance. It fills those arches perfectly without looking like a monster truck.
That 20x10 width forces a lot of wheel into the wheel well. At ET33, you sit right on the edge of the fender line. It avoids that sunken look we hate on factory setups.
We checked the caliper clearance and it is tight but safe. The concave spoke design provides just enough room for the stock S4 brakes. You do not need spacers here, which keeps the hub geometry clean.
The 66.6 hub bore fits the B8 platform like a glove. We love a hub-centric fitment because it eliminates vibration at high speeds. These wheels sit flush against the rotor hat.
The Solowerks coilovers pull the car down to eliminate that unsightly wheel gap. By dropping the ride height, we change the suspension geometry slightly. This setup puts the fender lip dangerously close to the tire shoulder.
Watch out for the inner fender liner at the front. With a 255/30/20 tire, you might get a light rub on big dips. Take your time dialing in the dampening to keep the tires off the plastic.
The barrel depth on these RFX10s gives the car serious weight. It looks substantial, not flimsy or cheap. It is the exact kind of presence this heavy sedan demands.
Overall, this fitment balances aesthetics with just enough aggression. It is a bold move that pays off when you see it rolling down the street.
What We Recommend for Audi S4 B8 Owners
Stick to a square setup for the B8. Staggering wheels on this Quattro system causes unnecessary headaches with the differential. A 20x10 square configuration is the gold standard for show and go.
Target an offset between ET30 and ET35 for the best flush look. Anything lower than ET30 risks poking out and throwing rocks at your paint. Anything higher than ET40 will look like a factory winter setup.
The 255/30/20 tire choice on this build is smart but tight. It provides a tiny bit of stretch to clear the fender lip. If you want more cushion, you could drop to a 19-inch wheel, but you lose the visual pop.
Don't fall for the cheap spacer trap. Buy wheels that fit the hub and offset requirements natively. Spacers introduce extra points of failure that you do not want at triple-digit speeds.
We always suggest a high-quality coilover kit like the Solowerks used here. Stock suspension cannot handle the geometry changes of a 10-inch wide wheel. Do not skimp on the suspension, or your fitment will look awkward.
Finally, always roll your fenders if you plan to go this low. Even a few millimeters of clearance prevents shredded tires on harsh pavement. It is cheap insurance for your investment.
Style and Build Analysis
The black-on-black aesthetic on this S4 works because of the texture variance. The glossy paint on the body contrasts perfectly with the metallic sheen of the RFX10s. It looks mean, purposeful, and clean.
I love the split-spoke design of the Rohana. It has enough open space to show off the rotors while maintaining a solid, muscular structure. It looks fast even when the car sits parked.
Proportions matter more than anything else in a build. This 20-inch diameter occupies the right amount of visual weight for the B8 body lines. It doesn't look like a cartoon, it looks like a refined tuner car.
Compared to other S4s we have seen, this one feels more mature. Many owners go for wild, neon-colored wheels that distract from the car. This build enhances the factory design instead of fighting it.
The road presence is undeniable. When this car rolls past, you notice the wheels first, then the low stance. It draws the eye and keeps it locked on the wheel arches.
This is how you modify a German sports sedan properly. You keep the lines sharp and the modifications intentional. The result is a car that looks like it belongs on a magazine cover.
Why We Love This Build
This black Audi S4 looks like it wants to hunt something down. The way the light dances off the deep concave spokes makes the whole car look lower and wider than it actually is. It fills the space with such authority that you cannot help but stop and stare. It is the perfect balance of stealth and performance.
We love this build because it feels complete. Every choice, from the specific Toyo tire to the coilover drop, works in harmony. It elevates the platform without ruining its daily drivability. This is exactly what we want to see at a local meet. Sometimes, you just nail the vision on the first try. This car is a total knockout.

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 20×10-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 20×10-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
