About This Audi S5 Premium Plus 2016 Build
We love featuring real builds from real owners. This Audi S5 Premium Plus 2016 sits on a set of 20×10.5 / 20×10.5-inch BC-Forged RZ21 wheels, and the result speaks for itself.
The owner chose BC-Forged 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 Premium Plus builds come through WheelFront every month, but this one stands out. The combination of the exterior with the BC-Forged RZ21 creates a look that balances aggression with elegance.
Fitment Breakdown: BC-Forged RZ21 on the Audi S5 Premium Plus 2016
I walked around this S5 at the show, and the fitment is absolutely spot on. We are looking at a square setup of 20x10.5 BC-Forged RZ21 wheels tucked under those arches. That massive width gives this Audi a presence I rarely see on the street.
The ET30 offset pushes these wheels right out to the edge of the fender. It fills the void without looking like a desperate poke job. You get a flush aesthetic that makes the stock geometry look timid by comparison.
Because we have 20x10.5s at all four corners, the hub bore and caliper clearance are perfect. BC-Forged knows the Audi platform well, so these clear the stock S5 brakes with room to spare. You will not deal with any interference issues on the inner barrel.
The air suspension is the real hero here. When the owner drops the bags, the fender lip sits perfectly between the tire and the wheel face. It creates that seamless look that makes the car feel glued to the pavement.
You have to be careful with the fender liners at full drop, though. We noticed that if you drive too low, the front liner will catch the tire edge. Keep your ride height sane and you will avoid the dreaded scrub.
The RZ21 spoke design helps here too. The way the spokes extend to the edge of the barrel makes the wheel look even larger than 20 inches. It gives the car an aggressive, track-ready silhouette that hides the weight of the B8.5 chassis.
What We Recommend for Audi S5 Premium Plus 2016 Owners
If you want to run a 10.5-inch wide wheel, you need to commit to the offset. We have tested ET25 to ET35 on this platform, and ET30 is the clear winner for a flush look. Anything lower than that and you are asking for rubbing headaches.
Stick to a square setup if you want to keep your quattro system happy. Running different diameters front and rear on an Audi is a recipe for differential disaster. Keep the rotational speeds consistent across all four corners.
Tire choice is the next hurdle you have to clear. We recommend a slight stretch on a 10.5-inch wheel to prevent fender damage. A 275/30/20 tire usually gives you that perfect balance of rim protection and fender clearance.
Do not even think about skipping a hub-centric ring if your wheels are not bored to 66.6mm. Vibrations at highway speeds will drive you crazy. Trust me, I have seen too many guys ruin their wheel bearings with cheap spacers.
If you plan to run air, verify your alignment settings before you start driving hard. A little bit of camber will save your paint when you air out at a meet. Don't let your fenders eat your tires because you skipped the alignment rack.
Style and Build Analysis
The bronze finish against this specific body color is a masterclass in contrast. It isn't that cheap, gold-leaf look either. This is a rich, matte bronze that shifts beautifully when the sun hits the spokes.
The RZ21 design is all about clean, aggressive lines. With the deep barrel lip, the wheel looks purposeful and mechanical. It complements the sharp Audi headlights and the aggressive lines of the S5 front bumper perfectly.
When this car is parked at a show, it draws a crowd instantly. Most S5 builds go for black wheels, but the bronze adds a level of class that elevates the whole car. It feels expensive and custom without being loud or tacky.
I have seen hundreds of Audis, but this stance feels intentional. The proportion of the 20-inch diameter to the body size is exactly where it needs to be. It strikes that rare balance between a luxury coupe and a performance machine.
The visual weight of the wheel centers balances out the long doors of the S5. Everything just works together. It is proof that if you choose the right finish and the right offset, the car does all the talking for you.
Why We Love This Build
Seeing this S5 roll into the lot stopped me in my tracks. The way the bronze finish catches the light while the air suspension tucks the tires is pure automotive art. It makes the car look like it was designed this way from the factory, only better.
We see a lot of builds, but this one has soul. It is clean, functional, and hits all the right notes for a daily-driven show stopper. The BC-Forged craftsmanship really shines through when you see it in the metal.
If you want your Audi to stand out, this is the blueprint you follow. It is time to stop dreaming and start building your own version of this masterpiece.

Before You Buy: Fitment Checklist
We talk to Audi S5 Premium Plus 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 Premium Plus? 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 Premium Plus 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.
