About This Audi S4 Base 2013 Build
We love featuring real builds from real owners. This Audi S4 Base 2013 sits on a set of 19×9.5 / 19×9.5-inch BC-Forged HBR2S 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 S4 Base builds come through WheelFront every month, but this one stands out. The combination of the exterior with the BC-Forged HBR2S creates a look that balances aggression with elegance.
Fitment Breakdown: BC-Forged HBR2S on the Audi S4 Base 2013
I walked around this B8.5 S4 for an hour at the meet, and the BC-Forged HBR2S setup caught my eye immediately. We rarely see a 19x9.5 square setup pulled off this cleanly on stock suspension. The 40 offset brings the wheels perfectly flush with the fender lines without needing those sketchy spacers.
The hub bore sits dead-on for the Audi platform, meaning no vibrations at highway speeds. We checked the caliper clearance, and those massive S4 brakes clear the spokes by a hair. It is a tight fit, but that is the beauty of a forged, custom-cut wheel.
The 9.5-inch width fills the wheel wells way better than the factory "peelers" ever could. You get a nice, purposeful stance that does not look like a cartoon. The barrel depth gives the side profile some much-needed aggression.
Because the owner kept the suspension stock, the fender gap remains functional but noticeable. I would warn you about potential rubbing on the inner liner if you decide to go with a beefier tire compound. Keep your tire sidewall profile sensible to avoid any nasty surprises on big dips.
The HBR2S spoke design manages to look both industrial and refined. It does not feel too busy, which keeps the Audi’s clean lines intact. We appreciate how the design draws your eyes straight to the rotor and caliper assembly.
Most folks run a wider offset and end up poking too far, but 40 is the secret sauce here. It keeps the scrub radius near factory specs so the steering feel stays sharp. This is exactly how a performance sedan should sit right out of the box.
What We Recommend for Audi S4 Base 2013 Owners
If you want to replicate this look, stick to the 19-inch diameter. Going up to 20s ruins the ride quality on these older B8.5 chassis. The 19x9.5 square setup is the gold standard for daily driving and occasional track use.
Do not even think about a staggered setup on an AWD Audi like this. You will absolutely trash your center differential if you mess with the rolling diameter ratios. Keep all four corners identical to keep the quattro system happy.
Aim for an offset between 35 and 40 if you want that flush look. Anything lower than 35 starts to poke and throws road debris all over your paint. We have seen too many guys ruin their quarter panels with overly aggressive offsets.
Regarding tires, stay away from extreme stretch unless you want to sacrifice every bit of grip. A 255 or 265 width tire pairs perfectly with a 9.5-inch rim. You get a nice, square sidewall that protects the lip from curb rash.
Avoid the temptation to use cheap cast wheels just to save a buck. This platform is heavy, and you need the strength of a forged wheel like the BC-Forged line. You will feel the difference in unsprung weight every time you hit a pothole.
Style and Build Analysis
The custom finish on these HBR2S wheels is the real MVP of the build. It shifts tones depending on how the sun hits the metal. Against the grey paint of this S4, it provides just enough contrast to pop without looking like a disco ball.
I love how the wheel design flows with the sharp, angular body lines of the B8.5. It looks like it could have been an OEM+ option from the Audi design studio back in the day. It is subtle, classy, and screams "I know what I am doing."
The stance achieves that perfect balance between luxury sedan and street brawler. You do not get the "donk" look of oversized wheels or the "track car" look of slammed coilovers. It sits exactly where the engineers probably intended it to sit.
We see a lot of these Audis at meets, but most people miss the mark on fitment. They either go too conservative or too wild with the camber settings. This build proves that simple, high-quality components beat flashy gimmicks every single time.
The proportions feel right because the wheels actually match the scale of the car. Many people forget that the S4 is a substantial machine that needs wheels with enough visual weight. These HBR2S wheels carry that weight with absolute confidence.
Why We Love This Build
I cannot stop thinking about the way this Audi looks when it rolls into the parking lot. The sunlight dances across those custom-finished spokes, highlighting every crisp machined detail. It fills the wheel arches with such authority that you cannot help but stare.
We see so many modified cars that look like science projects, but this one keeps the soul of the S4 intact. It is a masterclass in restraint and choosing the right parts for the job. This build reminds us why we fell in love with car culture in the first place.
Every time I see it, I want to go back to the shop and order a set for my own daily driver. It is the perfect blend of performance engineering and refined style. Perfection is just one wheel upgrade away.

Before You Buy: Fitment Checklist
We talk to Audi S4 Base owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 19×9.5 / 19×9.5-inch wheels fit my Audi S4 Base? 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 Base owners run 19×9.5 / 19×9.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
