About This Audi S4 B9 Build
We love featuring real builds from real owners. This Grey Audi S4 B9 sits on a set of 20×9.5-inch HRE P101 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 S4 builds come through WheelFront every month, but this one stands out. The combination of the Grey exterior with the HRE P101 creates a look that balances aggression with elegance.
Fitment Breakdown: HRE P101 on the Audi S4 B9
I walked around this B9 S4 for twenty minutes just staring at the wheels. The 20x9.5 HRE P101 setup is absolute perfection on this chassis. You get a wide footprint without turning the car into a track-only nightmare.
That ET35 offset hits the sweet spot for the B9 body. It pushes the face right out to the edge of the fender line. You get that flush look without sacrificing your paint job to road debris.
The P101 spokes offer incredible clearance for the factory S4 calipers. I checked the gap, and you have plenty of room to breathe. No custom spacer games required to keep the calipers from chewing up the barrels.
Running a 265/30/20 tire choice keeps the diameter nearly factory spec. You avoid speedo error and keep the Quattro system happy. It is a smart move for anyone daily driving their Audi.
The KW H.A.S. kit brings the body down just enough to eliminate that factory wheel gap. We saw zero rubbing during our test drive through the canyons. The tires tuck nicely under the arches during hard cornering.
The hub bore sits perfectly, so you get zero vibration at highway speeds. I felt the steering wheel at triple digits, and it stayed rock solid. These wheels feel like they came off the assembly line specifically for this grey sedan.
Watch the inner fender liners if you decide to go any lower, though. You might catch a plastic tab on big bumps if you slam it to the ground. Stick to this ride height and you will stay rub-free.
What We Recommend for Audi S4 B9 Owners
If you want a daily-friendly setup, 19s are the safe bet for ride quality. However, if you want the look, 20s are mandatory for the B9 wheel wells. Anything smaller looks lost in these big arches.
Stay away from aggressive offsets lower than ET30 unless you plan to pull your fenders. You will hate life when your tires start eating your paint. Stick to ET35 or ET40 to keep your clearance predictable.
We always suggest a square setup for an S4. Running the same width at all four corners keeps the handling neutral. You can actually rotate your tires, which saves you a fortune in the long run.
Don't be afraid to run a slightly wider tire if you have the clearance. A 265 width is the absolute limit before you start risking poke issues. Anything wider usually requires a compromise elsewhere.
Common mistakes usually involve cheap spacers and improper hub rings. Buy high-quality wheels like these HREs and bolt them directly to the hub. Spend the money once and never worry about your wheels again.
Style and Build Analysis
The grey paint on this B9 is subtle, but these HRE P101s make it pop. The contrast between the metallic body and the intricate spoke pattern looks sophisticated. It is a clean look that demands respect without screaming for attention.
I love how the P101 design shows off the internals of the brake assembly. The spokes are thin enough to look light but strong enough to suggest serious performance. It transforms the car from a commuter into a proper German sport sedan.
The proportions on this build are spot on for the B9 silhouette. The 20-inch diameter fills the visual weight of the car perfectly. It looks like it is moving even when it is parked at a coffee shop.
Compared to the other builds we feature, this one feels refined. We see a lot of people go overboard with wild colors and excessive camber. This owner chose restraint, and it paid off in spades.
The light catches the curves of the spokes differently from every angle. It adds a layer of depth that cheap cast wheels just cannot replicate. You are looking at top-tier manufacturing quality right here.
Why We Love This Build
This grey S4 grabs you the second you see it. The way the HRE P101 wheels hug the fenders makes the whole car look planted and mean. It is the perfect blend of luxury and aggression that every Audi owner secretly craves.
Seeing it roll down the street with the suspension tightened up is a real treat. The light hits the wheels and the body lines in a way that just feels right. It is a masterclass in how to build a clean street car.
If you want your B9 to turn heads without looking like a toy, build it exactly like this. This is the gold standard for Audi fitment. Just do it.

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 20×9.5-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 20×9.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
