About This Audi S4 B8 Build
We love featuring real builds from real owners. This Blue Audi S4 B8 sits on a set of 19×9.5-inch 305 Forged FT105 wheels, and the result speaks for itself.
The owner chose 305 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 builds come through WheelFront every month, but this one stands out. The combination of the Blue exterior with the 305 Forged FT105 creates a look that balances aggression with elegance.
Fitment Breakdown: 305 Forged FT105 on the Audi S4 B8
I walked around this B8 S4 for twenty minutes just staring at the fitment. The 19x9.5 setup fills the wheel wells exactly how Audi engineers should have done from the factory. We are running a +40 offset here, which sits perfectly flush with the fenders.
The B8 chassis is notoriously picky about wheel width and offset. If you push the offset too low, you deal with poke and ugly fender rub. At +40, these FT105s tuck right inside the factory arches without a struggle.
Clearing the massive factory S4 brakes is usually a nightmare with aftermarket wheels. These 305 Forged barrels provide plenty of room for those front calipers to breathe. I saw zero signs of contact or clearance issues during our inspection.
The hub bore on these wheels matches the Audi platform perfectly, so you avoid vibration headaches. You do not need annoying centering rings that break or warp over time. Everything locks into place with solid, factory-like precision.
I love the concave profile of the FT105 spokes on this width. The 9.5-inch width gives the wheel a deep, aggressive look that you just cannot get on a thinner rim. It adds a layer of depth that makes the car look wider from the rear.
If you plan to slam the car on coilovers, watch your inner clearance at the control arms. We have seen some builds rub on the inner liner during full lock, but this specific setup clears just fine. Keep your alignment specs tight to avoid any unwanted scrubbing.
What We Recommend for Audi S4 B8 Owners
If you own a B8, do not go chasing extreme widths that ruin your handling. We always recommend staying in that 9.0 to 9.5-inch width range for the best balance. Anything wider just creates unnecessary tramlining on the highway.
Stick to a square setup if you actually drive your S4 hard in the canyons. Staggered setups on these Quattro systems play havoc with the center differential over time. You want four identical tires to keep that AWD system happy and predictable.
For offsets, keep your target between +38 and +42. This range keeps the scrub radius close to stock and prevents premature wheel bearing wear. If you drop the car, adjust your camber slightly to tuck the top of the tire.
Avoid the temptation to run cheap, thin spacers just to gain a few millimeters of poke. High-quality wheels like these 305 Forged units are engineered to sit correctly without extra hardware. Every spacer you add introduces another point of potential failure.
Match your tire choice to your actual driving habits, not just the look. A 255/35/19 tire works beautifully on a 9.5-inch rim to provide a clean, square sidewall. It gives you enough protection against potholes while keeping the look crisp and professional.
Style and Build Analysis
The Hyper Silver finish against this deep blue paint creates a timeless, classy aesthetic. It avoids the tired look of matte black wheels that hide all the intricate spoke details. The silver reflects the light beautifully as the car rolls through a parking lot.
I appreciate the design of the FT105 because it feels sophisticated rather than overly busy. The spokes are clean, sharp, and purposeful without trying too hard to look like a drift car. It complements the S4’s understated, muscular German lines perfectly.
The stance defines the entire character of this build. With the wheels pushed out to the edge, the car looks planted and ready to attack a corner. It completely eliminates the bloated, factory-sunken look that plagues most B8 sedans.
Compared to other builds we have featured, this one shows restraint. It does not rely on massive aero or neon colors to grab your attention. The quality of the wheel finish alone does all the heavy lifting here.
This car looks like a serious performance sedan that drives as good as it looks. The proportions feel balanced, and the silver pop against the blue makes the car stand out in a crowd. It is a masterclass in how to upgrade a platform without ruining its soul.
Why We Love This Build
This Audi S4 is exactly how a daily-driven street weapon should look. The way the Hyper Silver catches the sun against that deep blue paint makes the whole car glow under the streetlights. Every time I glance at the wheel arch, I see that perfect, tight gap that screams quality.
We see a lot of builds, but this one sticks in my mind because it gets the small details right. It is aggressive without being tacky, and it is refined enough to park at any upscale meet. It turns the stock S4 into something that looks like it belongs on a racing circuit.
If you want to transform your own B8, start right here with this blueprint. This setup is the gold standard for anyone who values performance and style in equal measure. This is the perfect look for a B8 S4.

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 19×9.5-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 19×9.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
