About This Audi S4 B9 Build
We love featuring real builds from real owners. This Blue Audi S4 B9 sits on a set of 20×10-inch BC Forged MLE05 wheels, and the result speaks for itself.
The owner chose BC 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 BC Forged MLE05 creates a look that balances aggression with elegance.
Fitment Breakdown: BC Forged MLE05 on the Audi S4 B9
I walked around this B9 S4 for a solid ten minutes at the show, and the fitment is perfection. We are looking at a 20x10 setup that fills those arches exactly how Audi should have from the factory. The BC Forged MLE05 design uses a deep barrel to really push the visual weight outward.
Getting a 10-inch wide wheel under the B9 fenders requires a precise offset to avoid poking. We checked the clearance, and these sit flush with the fender line without looking like a monster truck. You need to watch your offset here, or you will be chewing up your fender liners on every bump.
The MLE05 design provides killer clearance for the factory S4 calipers. Many aftermarket wheels force you into spacers, but these BC Forged barrels clear the big brakes with room to breathe. That creates a clean look that does not require cheap hardware to make it work.
The hub bore on these is machined specifically for the Audi 66.5mm hub. We hate using hub-centric rings because they eventually vibrate and drive you crazy. These sit tight on the hub for a factory-level connection that stays smooth at highway speeds.
The ABT H.A.S. suspension makes this whole package come alive. It drops the car just enough to eliminate the unsightly wheel gap without ruining the ride quality. You get that aggressive static look while keeping the functional damper control of the stock system.
We did notice the front fender liners are tight when you hit a dip at full lock. If you drive like a maniac, you might need to trim the plastic tabs near the screw mounting points. A little bit of heat and a gentle roll go a long way on this platform.
The polished lip provides a perfect transition from the tire bead to the inner spoke face. It breaks up the dark wheel and keeps the setup from looking like a black hole in the wheel well. This is exactly how you dial in a B9.
What We Recommend for Audi S4 B9 Owners
Stop overthinking your setup and stick to a square 20x10 configuration. We have tested staggered setups on this chassis, and they just mess with the Quattro system's brain. Keep all four wheels the same size to protect your differential and keep the car feeling sharp.
For the offset, aim for an ET30 to ET35 range. If you go lower than ET30, you will be fighting fender scrub on every turn. Anything higher than ET35, and the wheels look sunken and weak against the S4 body lines.
Don't be afraid of a little tire stretch if you want that ultra-flush look. A 255/30/20 tire works beautifully on a 10-inch rim to give you that crisp sidewall profile. It protects the wheel lip while keeping the handling response tight and predictable.
Avoid cheap cast wheels if you plan on running 20-inch diameters. The B9 S4 is a heavy, powerful car that will bend soft wheels on the first pothole you hit. Invest in forged wheels like these BCs so you can actually drive the car hard.
Always double-check your alignment settings after you drop the car on springs or coilovers. You want to dial in enough negative camber to tuck the tires, but not so much that you ruin your daily driving comfort. A proper alignment is the cheapest performance mod you can buy.
Style and Build Analysis
That blue paint on this S4 is absolutely deep. When the sun hits the gunmetal finish on the MLE05 wheels, the contrast is aggressive and refined at the same time. The polished lip catches the light just enough to draw your eye toward the rolling hardware.
The MLE05 spoke design feels like a modern evolution of the classic mesh style. It has enough detail to look intricate, but it stays open enough to show off those beefy brake calipers. It is a sophisticated choice that matches the B9's sharp, angular aesthetic.
Proportions are everything in this game, and this car nails it. The 20-inch wheels fill the arches without looking like wagon wheels. It sits low and angry, giving the car a road presence that makes you look twice in the parking lot.
Most people ruin a good S4 with garish colors or oversized tires, but this owner showed restraint. By sticking to a muted gunmetal and silver theme, they let the body lines of the Audi do the talking. It looks like a high-end build that could have come from a catalog.
We see a lot of "all-black" builds that just get lost in the shadows, but this is different. The polished lip creates a distinct line between the tire and the wheel. It gives the car a sense of movement even when it is standing perfectly still.
Why We Love This Build
This car is the perfect example of how a few choice mods can transform a daily driver into a showstopper. The blue paint pops against the gunmetal BC Forged wheels like nothing else on the road today. Every time the car rolls forward, those polished lips shimmer and catch the light, drawing everyone’s attention.
The way the ABT suspension tucks the tires into the fenders creates a stance that feels both athletic and premium. It sits exactly where it needs to, looking ready to carve canyons or pull up to a luxury hotel. You can tell the owner cares about every single millimeter of clearance.
This build stops us in our tracks because it is tasteful, balanced, and undeniably fast-looking. It makes us want to ditch our stock wheels and get on the phone with BC Forged immediately. This is the new benchmark for the B9 platform.

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 20×10-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 20×10-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
