About This Audi S4 Premium Plus 2018 Build
We love featuring real builds from real owners. This Audi S4 Premium Plus 2018 sits on a set of 19×9.5 / 19×9.5-inch Kansei KNP wheels, and the result speaks for itself.
The owner chose Kansei 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 Premium Plus builds come through WheelFront every month, but this one stands out. The combination of the exterior with the Kansei KNP creates a look that balances aggression with elegance.
Fitment Breakdown: Kansei KNP on the Audi S4 Premium Plus 2018
I walked around this S4 for twenty minutes just to soak in the lines. Fitting 19x9.5 square Kansei KNPs with a +22 offset on this chassis is a bold move. Most people stick to conservative specs, but this setup demands your full attention.
The +22 offset pushes these wheels right to the edge of the B9 fenders. You get that aggressive, flush look that every enthusiast chases. I noticed the poke is significant, so you need that air suspension to tuck the hardware when you park.
Kansei nailed the spoke design on the KNP for this specific brake setup. The spokes clear those stock Audi calipers with room to spare. You won't need to hunt for massive spacers just to get the wheels to spin.
Hub bore sizing is critical on these German machines. I checked the hub rings, and everything seats perfectly to prevent those nasty high-speed vibrations. Proper fitment is all about the details behind the mounting plate.
The barrel depth on these 19s gives the car a muscular, planted stance. Because we are running a 9.5 width, the tires sit with a slight, purposeful stretch. It looks intentional rather than sloppy or dangerous.
Watch your front fender liners closely if you plan to drive low. At this offset, the tires will catch the liner tabs if you don't manage your air pressure correctly. It is a small price to pay for this level of visual impact.
What We Recommend for Audi S4 Premium Plus 2018 Owners
If you want to replicate this look, stick to the 19-inch diameter. Going to 20s kills your tire sidewall and ruins the ride quality on these platforms. Keep it functional so you can actually drive the car hard.
The +22 offset is pushing the limit for a daily driver. If you want a more relaxed fitment, look for something in the +35 to +40 range. You lose a bit of that deep-dish aesthetic, but you gain peace of mind on rough roads.
I always suggest a square setup like this one for the S4. It allows you to rotate your tires properly and keeps the Quattro system happy. Staggered setups on these cars often cause more headaches than they are worth.
Don't skimp on your tire choice when running a wide wheel. Grab a high-performance summer tire with a rim protector bead if you can find one. It keeps the edge of your beautiful Gray wheels from meeting every curb in the city.
Avoid cheap spacers at all costs if you need to adjust your clearance. Quality hub-centric spacers are the only way to go if you find you are rubbing on the inside. Do it right the first time or save your money until you can.
Style and Build Analysis
The Gray finish on these Kansei KNPs is pure class. It creates a subtle, moody contrast against the factory Audi paint. It feels industrial and clean without being loud or obnoxious.
I love the six-spoke design of the KNP. It nods to old-school JDM racing wheels while looking right at home on a modern German sport sedan. The proportions feel perfectly balanced from every single angle.
When the car airs out, the top of the tire disappears behind the fender arch. The wheel face looks like it is fused with the bodywork. It creates a seamless flow that makes the car look like a concept sketch.
Most S4 builds I see are way too busy with carbon fiber and flashy colors. This one lets the wheels do the talking. It is restrained, confident, and incredibly well-executed for a street build.
The way the light hits the concave face of the wheel is hypnotic. It gives the car a sense of movement even when it sits dead still in a parking lot. This is exactly how you modify a premium sedan.
Why We Love This Build
This S4 build hits every single mark for me. When the sun hits that Gray finish, the Kansei KNPs pop against the dark paint perfectly. The air suspension drops the frame over the barrel lips to create a stance that feels both aggressive and refined.
It is not just a car; it is a statement about how clean a modern German build can look. I stare at those wheels and think about how they transform the entire silhouette of the B9. This is the kind of setup that stops traffic at every single meet.
Everything about this car feels dialed in and intentional. Stop dreaming about a better stance and just get the parts already.

Before You Buy: Fitment Checklist
We talk to Audi S4 Premium Plus 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 Premium Plus? 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 Premium Plus 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.
