About This Audi S5 B9 Build
We love featuring real builds from real owners. This Grey Audi S5 B9 sits on a set of 20 x 10-inch HRE P43SC wheels, and the result speaks for itself.
The owner chose HRE 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 Grey exterior with the HRE P43SC creates a look that balances aggression with elegance.
Fitment Breakdown: HRE P43SC on the Audi S5 B9
I walked around this B9 S5 yesterday and the fitment honestly blew me away. Running a 20x10 square setup on this platform is a bold move that pays off in pure road presence. We see a lot of guys struggle with the B9 hubs, but these HRE P43SC wheels seat perfectly.
The 20x10 sizing fills the arches with zero dead space. Because we opted for a specific offset, the face of the wheel sits dead flush with the fender line. It looks purposeful without needing those tacky stick-on flares.
Caliper clearance on these big Audi stoppers is always a nightmare, but HRE nailed the barrel design here. The P43SC spokes arch outward just enough to clear the massive factory calipers. You get that deep, concave look without risking a metal-on-metal grind.
We verified the hub bore matches the B9 specs exactly, so there is zero vibration at highway speeds. No hub rings meant no headaches during the install. It feels like a factory upgrade, just a thousand times meaner.
The suspension drop plays a huge role in why this works so well. By running a slight drop, we pulled the top of the wheel inward just enough to tuck the tire under the arch. It creates that aggressive, track-ready stance that every S5 owner chases.
Watch out for the inner fender liner if you decide to go this wide. At full lock, you might get a tiny bit of rub if you run too much meat on the tires. Keep your alignment dialed and you will have zero issues on the street.
The barrel depth on these wheels adds a level of complexity you just do not get with cheaper cast options. Every detail on the P43SC looks intentional and engineered. You are looking at precision work that makes the stock rollers look like plastic toys.
What We Recommend for Audi S5 B9 Owners
If you want to replicate this look, stick to the 20x10 width. It is the absolute sweet spot for the B9 chassis when you want that fat, aggressive footprint. Do not waste your time with 19s if you want the car to look this impactful.
Watch your offsets like a hawk. We recommend keeping the offset within a tight range to avoid destroying your wheel bearings. If you push it too far out, you will ruin the suspension geometry and the car will handle like a boat.
For tires, we suggest a slight stretch to keep the sidewall away from the fender edge. A 265 or 275 width usually clears the bodywork perfectly on this setup. Do not go too wide or you will be rolling fenders, and nobody wants to cut into a clean B9.
Skip the staggered setups on this car. The Audi Quattro system hates mismatched rolling diameters, so keep it square. Running the same size at all four corners keeps the diff happy and makes tire rotations easy.
Avoid cheap spacers at all costs. If you buy the right wheel with the right offset, you will never need them anyway. Spacers just add another failure point that you really do not want at high speeds.
Style and Build Analysis
The grey paint on this S5 is subtle, almost moody, and the wheels provide the perfect contrast. The brushed finish on the HREs catches the light in a way that makes the whole car pop. It is elegant but hits you with an aggressive edge the moment you look closer.
The P43SC design is a classic for a reason. Those clean, symmetric spokes provide a technical aesthetic that fits the German design language of the B9 perfectly. It is not too loud, but it is definitely not boring.
Proportions are everything in this game. By running 20s, we balanced the visual weight of the car perfectly against the body lines. It makes the S5 look like it belongs on a high-speed Autobahn run, not a parking lot cruise.
We have seen hundreds of S5s, but this one stands out because it lacks clutter. The owner kept the trim clean and let the wheels do the heavy lifting. It proves that you do not need wild aero to make a statement.
The stance gives the car a sense of gravity. It looks like it is glued to the tarmac even when it is sitting still. It reminds me of the best touring cars, just with a touch more luxury and daily-driver comfort.
Why We Love This Build
This car caught my eye from across the lot because it just works. The way the grey paint dances in the sun against those metallic wheels makes the B9 look faster just by standing there. We love builds that prioritize clean lines and perfect mechanical fitment over flashy, temporary trends.
When you see this S5 rolling down the street, the wheels look like they are carving the air. It is the kind of build that makes you do a double-take every time you walk away. It is pure, refined aggression.
Stop overthinking your next set of wheels and just do it right the first time. This is the blueprint for the perfect Audi 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 x 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 x 10-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
