About This Audi S5 B8 Build
We love featuring real builds from real owners. This Red Audi S5 B8 sits on a set of 20×10-inch BC Forged RZ05 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 builds come through WheelFront every month, but this one stands out. The combination of the Red exterior with the BC Forged RZ05 creates a look that balances aggression with elegance.
Fitment Breakdown: BC Forged RZ05 on the Audi S5 B8
I walked around this B8 S5 for twenty minutes yesterday, and the stance is perfect. We are looking at 20x10 BC Forged RZ05 wheels with a +25 offset all around. That width pushes the wheels right to the edge of the fender line without looking like a cartoon.
The +25 offset is aggressive for this platform, but it works. It clears the massive factory calipers with plenty of room to breathe. I love how the hub bore sits perfectly flush against the Audi hubs.
Those 275/30/20 tires provide the right amount of sidewall to avoid looking like rubber bands. The fitment is tight, but the H&R coilovers keep everything tucked precisely where it needs to be. You get that clean, slammed look without killing the daily drivability.
Check out the barrel depth on these RZ05s. The design creates a deep, concave profile that makes the car look wider than stock. Every spoke flows naturally into the center, giving the Audi a much more planted aesthetic.
We need to talk about the fender clearance. With this setup, the tires sit dangerously close to the inner liner during full lock. If you drive over a massive pothole, you might hear a faint whisper of contact.
The H&R coilovers dial out the body roll, which helps keep the tires from chewing up the plastic liners. Most guys try to go wider, but this 275 setup is the absolute limit for a B8. I would not change a single thing about these specs.
The brushed black finish hides brake dust better than any gloss option. It keeps the wheel design sharp even when the car is dirty. This is a functional, track-ready fitment that happens to look like a million bucks.
What We Recommend for Audi S5 B8 Owners
If you own a B8, do not go wider than 10 inches unless you want to pull your fenders. A 10-inch width is the sweet spot for these wide arches. You get the concave look without the body shop nightmares.
Aim for an offset between +25 and +30. Anything higher than +30 starts to look sunken and weak under these big fenders. We have tested many setups, and +25 is the gold standard for that flush, aggressive look.
Forget about staggered setups on the S5. This car is Quattro, so keep the rolling diameter identical on all four corners to save your center differential. Square setups make tire rotations easy and keep the handling predictable.
Avoid excessive tire stretch if you actually drive your car. A 275-width tire on a 10-inch wheel gives you a nice, square shoulder that protects the rim. It looks aggressive and performs exactly how Audi intended.
Many owners make the mistake of using generic spacers to fix bad fitment. Do not do that. Buy the right offset from the start and skip the vibration headaches caused by cheap spacers.
Style and Build Analysis
The visual impact of this red paint paired with brushed black wheels is undeniable. Red is a loud color, so the dark, textured wheels ground the car visually. It looks meaner and more purposeful than a chrome or silver wheel ever could.
The RZ05 design features sharp, angular spokes that mimic the aggressive lines of the S5 body. It carries a technical, racing-inspired vibe that feels at home on a canyon road. You can tell this build was carefully curated.
I have seen a lot of B8 builds, but this one hits differently. Many people go for overly polished wheels that clash with the car's curves. These BC Forged rollers let the bodywork do the talking while adding a layer of modern sophistication.
The stance makes the S5 look like it is ready to hunt down a supercar. It does not have that awkward gap that plagues stock Audis. Everything is locked in, calculated, and perfectly balanced.
When you catch this car in the sunlight, the brushed finish reveals intricate metalwork. It is not just a flat black paint job; it has depth and character. It proves that a wheel choice can totally redefine the personality of a chassis.
Why We Love This Build
This red Audi S5 is the perfect example of how a few choice mods can transform a platform. The way the light dances off that deep red paint while the brushed black wheels swallow the road is intoxicating. Every time I glance back at it, I find a new detail to appreciate in the spokes.
It is not just a show car meant to sit in a parking lot. You can tell this machine wants to be driven hard through a tight mountain pass. It captures that elusive balance between aggressive street presence and mechanical precision that we all crave.
Stop overthinking your next set of wheels and just do this. This is the definitive look for the B8 S5.

Before You Buy: Fitment Checklist
We talk to Audi S5 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 S5? 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 owners run 20×10-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
