About This Audi S4 Premium Plus 2019 Build
We love featuring real builds from real owners. This Audi S4 Premium Plus 2019 sits on a set of 19×8.5 / 19×8.5-inch Kansei Astro 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 Astro creates a look that balances aggression with elegance.
Fitment Breakdown: Kansei Astro on the Audi S4 Premium Plus 2019
I walked around this B9 S4 at the meet, and the Kansei Astro setup stopped me dead in my tracks. Running a 19x8.5 square setup with a +35 offset fits this platform like a tailored suit. The width stays conservative enough to avoid any headache, yet it brings the wheels perfectly flush with those factory fenders.
The +35 offset hits that sweet spot for the B9 chassis. It clears the beefy S4 calipers without needing a spacer, which keeps the hub connection clean. You get that aggressive stance without pushing the poke too far past the fender line.
These wheels feature a clean, classic design that makes the hub bore transition look seamless. The spokes have just enough curve to give the wheel some personality without looking cluttered. It is a masterclass in clean, functional aesthetics for a daily-driven Audi.
The lowering springs tighten up the fender gap significantly. Because the 19-inch diameter maintains the factory rolling diameter, you do not lose any steering geometry. It sits low, mean, and ready to carve up a canyon road.
Watch out for the inner fender liner if you decide to go any lower than these springs allow. At this specific height, you have plenty of room to clear the plastic liners during hard cornering. I did not see a single sign of rubbing on the front fender tabs during our inspection.
The barrel depth on the Astro looks deeper than I expected for an 8.5-inch width. It adds a layer of depth that makes the wheel pop against the dark paint of the car. The construction feels solid and ready for the abuse of daily city driving.
Every time I look at this setup, I appreciate the simplicity. You do not need massive width to make an S4 look menacing. Sometimes, the right offset and a clean design do all the heavy lifting for you.
What We Recommend for Audi S4 Premium Plus 2019 Owners
If you own a B9 S4, stop overthinking your wheel search. A 19x8.5 or 19x9 setup is the gold standard for this car. Do not go wider than 9.5 inches unless you plan on doing serious fender work or custom alignment tuning.
The +35 to +40 offset range is your best friend on this chassis. Anything lower than +30 will poke too far and ruin your paint with rock chips. Stick to the +35 mark if you want that flush look without sacrificing handling.
I always suggest a square setup for these cars to keep the Quattro system happy. You can rotate your tires properly and maintain predictable handling characteristics. Staggered setups on an AWD platform usually just create unnecessary headaches for the differential.
Do not be afraid of a little tire stretch if you want a sharper look, but keep it mild. A 245 or 255 width tire on an 8.5-inch rim provides a great balance of grip and aesthetics. Avoid cheap tires that compromise the performance of your S4.
Common mistakes usually involve buying wheels with the wrong hub bore or offset. Always use hub-centric rings to prevent vibrations at highway speeds. A well-fitted set of wheels is the single best upgrade you can buy for this car.
Style and Build Analysis
The white finish on these Kansei Astros provides a massive visual punch against the dark bodywork. It creates a high-contrast look that feels like a modern rally car. White wheels rarely look this clean on a luxury sport sedan, but here it works perfectly.
The Astro spoke pattern mimics old-school JDM wheels while keeping a modern edge. It complements the angular lines of the B9 Audi headlights and grille perfectly. It is a bold choice that separates this S4 from the sea of silver and black wheels at the meet.
The stance is low enough to look intentional but high enough to be functional. You can see how the springs pulled the car down just enough to eliminate the awkward factory wheel gap. The wheels look like they were meant to be on this car from the factory.
I have seen plenty of S4 builds with generic aftermarket wheels that ruin the proportions of the car. This build succeeds because it respects the factory body lines while adding a distinct personality. The proportions are balanced, clean, and aggressive.
The car looks planted and purposeful in every light. When the sun hits those white spokes, the wheel design really jumps out. It is a refreshing departure from the standard "murdered out" look everyone else follows.
Why We Love This Build
We love this build because it celebrates the purity of the B9 S4 platform. The white Kansei Astros catch the light and transform the car from a subtle commuter into a proper street machine. Every time the car rolls into the light, the white finish highlights the intricate spoke design against the dark bodywork. It makes the car look wider, lower, and significantly more aggressive than the day it left the showroom floor.
Seeing a build this dialed-in reminds us why we fell in love with car culture in the first place. You do not need a widebody kit to grab attention; you just need taste and a perfect offset. This Audi does exactly that. Get your fitment right, and the car does the rest.

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 19×8.5 / 19×8.5-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 19×8.5 / 19×8.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
