About This Audi S4 Base 2000 Build
We love featuring real builds from real owners. This Audi S4 Base 2000 sits on a set of 18×9 / 18×9-inch Enkei RPF1 wheels, and the result speaks for itself.
The owner chose Enkei 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 Enkei RPF1 creates a look that balances aggression with elegance.

Fitment Breakdown: Enkei RPF1 on the Audi S4 Base 2000
I walked up to this B5 S4 and knew instantly that the 18x9 setup hit the mark. The 35 offset sits perfectly flush with the fenders without looking cartoonish. This width fills the wheel wells in a way the factory wheels never could.
The RPF1 is legendary for a reason, but fitting them on an S4 requires focus. We worried about those massive front HP2 calipers hitting the spokes. Luckily, this barrel design clears the iron perfectly without needing extra spacers.
The 5x112 bolt pattern fits the hub like a glove. We always recommend hub-centric rings to ensure you do not get any vibration at speed. You need that snug connection to handle the Quattro system's power.
The air suspension changes the game entirely here. At ride height, the car looks aggressive and ready to attack a back road. When the owner drops the bags, the tire tucks right inside the fender liner.

You have to watch the inner fender liners on these B5 chassis. If you go too low without proper alignment, the rubber will catch the liner on a hard turn. A little fender roll goes a long way to keep the paint safe.
The lip depth on these RPF1s is subtle but effective. It gives the wheel enough dimension to break up the flat face of the design. It keeps the classic racing aesthetic that Enkei is famous for.
What We Recommend for Audi S4 Base 2000 Owners
If you want this look, stick to an 18-inch diameter. Anything smaller looks lost in the arches, and 19s just kill the ride quality on these old platforms. Aim for a 9-inch width if you want that meaty, aggressive stance.
We always suggest a square setup for these cars. Quattro systems hate staggered tire diameters, so keep it even on all four corners. It makes tire rotation easy and keeps the handling neutral.

Watch your offset closely. Anything higher than 35 will tuck too far inside and look weak. Anything lower than 30 might poke past the fender, which ruins the clean lines of the S4.
Do not skip on high-quality tires. You have a turbocharged V6 pushing power to all four wheels, so you need grip. A slight stretch looks cool, but do not sacrifice your safety for a trend.
Check your control arms before you drop the car on air. These B5s are notorious for worn bushings that ruin your alignment specs. Fix the suspension first, then bolt on the wheels.
Style and Build Analysis
This gunmetal finish is the secret sauce for this build. It pulls the dark tones out of the body paint and gives the whole car a sinister, industrial vibe. It hides brake dust better than silver, too.

The Enkei RPF1 is a busy wheel, but it works on the B5. It adds a technical, motorsport-inspired contrast to the smooth, rounded lines of the S4 body. It looks like it belongs on a hill climb stage.
The stance is absolute perfection. Seeing the wheel face align with the arch when the bags are aired out is pure art. You can tell the owner spent hours dialing in the fitment to get that exact clearance.
Proportions matter more than anything else in a build. These 18s fill the gap without making the car look like a monster truck. It keeps the factory silhouette while updating the character entirely.
Compared to other S4s with heavy, cheap cast wheels, this car looks light and nimble. The RPF1 is known for being feathery, and it shows in the way the car moves. It is functional, purposeful, and damn good to look at.
Why We Love This Build
I stopped dead in my tracks when I saw this car parked under the lot lights. The gunmetal finish caught the glow, highlighting those iconic thin spokes against the deep paint. It looks like a factory prototype that Audi forgot to put into production.
Every time the owner hits the switch to dump the air, the car hugs the pavement. It transforms from a street cruiser into a grounded, track-ready beast. This build proves that you do not need over-the-top body kits to make an impression.
This S4 is the reason we fell in love with modifying cars in the first place. It hits the perfect balance of form and function. Get the fitment right, and the car builds itself.

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 18×9 / 18×9-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 18×9 / 18×9-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
