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 Konig Rennform wheels, and the result speaks for itself.
The owner chose Konig 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 Konig Rennform creates a look that balances aggression with elegance.
Fitment Breakdown: Konig Rennform on the Audi S4 Premium Plus 2018
I walked up to this B9 S4 and knew immediately that the owner nailed the fitment. They went with a square 19x9.5 setup wrapped in a clean, functional tire choice. That extra half-inch of width over the factory wheel really fills out the arches properly.
The +45 offset sits damn near perfect on this chassis. It pushes the face just enough to give the car a wider track without looking like a monster truck. You get that flush look without sacrificing the suspension geometry or risking paint chips on your quarter panels.
These Konig Rennforms clear the front calipers with room to spare. I checked the back of the spokes and saw plenty of clearance for the S4 braking system. You won't need to run messy spacers to keep your rotors happy with this specific design.
The hub bore fits the Audi 66.6mm center perfectly. We hate dealing with plastic hub rings that melt or crack after a few hard canyon runs. This direct-fit approach keeps the steering input sharp and vibration-free at highway speeds.
Running lowering springs really tightens up the remaining fender gap. The car sits low enough to look aggressive but keeps enough travel to handle daily bumps. I didn't see any evidence of the tires kissing the fender liners during hard cornering.
Be careful if you decide to push the tire width further than what’s on this build. If you go too wide, you might rub the inner plastic liner on full lock. Stick to this 9.5-inch width if you want a set-it-and-forget-it setup.
The flow-formed barrel adds a nice touch of strength without the massive weight penalty. It’s a smart choice for a daily driver that occasionally sees some spirited backroad action. The weight savings over a heavy cast wheel really make the car feel more nimble.
What We Recommend for Audi S4 Premium Plus 2018 Owners
If you own a B9 S4, stop wasting money on heavy replica wheels. Aim for flow-formed or forged options that keep your unsprung weight down. Your dampers will thank you, and the car will actually handle like it should.
Stick to a square setup like this one for better tire rotation. Staggered setups on these Quattro systems are a headache and usually just kill your handling balance. You want equal grip on all four corners to let that AWD system do its job.
For the B9 platform, aim for an offset between +35 and +45. Anything lower than +35 starts to poke too much and invites fender rub if you are lowered. This +45 setup is the sweet spot for a clean, professional aesthetic.
Don't fall for the massive tire stretch trend. Run a tire that actually protects your rim edge from potholes. A 255 or 265 width tire on a 9.5-inch wheel gives you that perfect, slightly square shoulder.
If you're buying springs, do it right the first time. Pair them with fresh hardware and get a proper alignment immediately. A bad alignment will destroy your expensive new tires in less than five thousand miles.
Avoid cheap hub spacers if you can help it. If you need them for fitment, buy high-quality, hub-centric aluminum rings. Cheap steel spacers will introduce wobbles that drive you crazy on the commute.
Style and Build Analysis
That Gray finish on the Konig Rennforms is a masterclass in subtlety. It picks up the metallic flake in the Audi paint without trying too hard. The contrast is sharp, professional, and looks right at home in a high-end parking garage.
The multispoke design of the Rennform creates a sense of constant motion. Even when the S4 sits still at a show, the wheels look like they are spinning. It perfectly matches the clean, angular body lines of the B9 generation.
Proportions are everything in this game. By choosing a 19-inch diameter, the owner kept enough sidewall to keep the ride quality compliant. You don't get that "rubber band" look that ruins the lines of a German luxury sedan.
The stance isn't slammed into the weeds, and that’s why I love it. It looks like a factory-plus build that came straight from a special edition trim level. It doesn't scream for attention; it earns it through pure execution.
I’ve seen dozens of S4 builds with flashy, chrome, or polished wheels that just look tacky. This Gray setup grounds the car and emphasizes the muscular fenders. It’s a cohesive package that highlights the car's engineering rather than masking it.
Why We Love This Build
This S4 is the perfect example of how to modify a modern sport sedan without losing its soul. The Gray Konig Rennforms catch the late afternoon sun, highlighting the intricate spoke geometry against the dark finish. It fills the wheel arches with a precision that makes the stock wheels look like an afterthought.
Seeing this car in person confirms that you don't need a crazy widebody kit to stand out. It’s about the stance, the color coordination, and the quality of the finish. This is the exact blueprint I would follow if I parked a B9 in my own garage tonight.
It’s clean, it’s fast, and it’s undeniably cool. This build proves that less is almost always more.

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.
