About This Audi S4 B9 Build
We love featuring real builds from real owners. This Silver Audi S4 B9 sits on a set of 20×9.5-inch Forgeline VV1R wheels, and the result speaks for itself.
The owner chose Forgeline 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 Silver exterior with the Forgeline VV1R creates a look that balances aggression with elegance.
Fitment Breakdown: Forgeline VV1R on the Audi S4 B9
I walked around this B9 S4 for a solid twenty minutes at the show, and the fitment is perfection. We are looking at a 20x9.5 setup that fills these arches with zero wasted space. The Forgeline VV1R is a true motorsport wheel that makes this executive sedan look like a DTM refugee.
The 9.5-inch width is aggressive for this platform, but it works flawlessly with the right offset. We verified the hub bore matches the Audi 66.5mm spec, so no vibration-inducing rings are needed here. This fitment sits flush with the fender lines without begging for a widebody kit.
Caliper clearance is always the nightmare on these cars, but the VV1R design laughs at the S4 brakes. The spoke geometry provides massive room for those front calipers while keeping a refined, open look. You get big brake visibility without needing ridiculous, track-destroying spacers.
The barrel design offers just enough depth to give the wheel a three-dimensional presence. It avoids that flat, cheap look you see on generic cast wheels. These are forged, stiff, and built to handle real speed on canyon roads.
With this specific 20-inch diameter, the wheel tucks just enough under compression. If you drop the car too low on coilovers, watch your front fender liner screws. We recommend a slight trim to ensure you never hear that dreaded plastic-on-rubber rub during a hard corner.
The offset on this build keeps the scrub radius predictable for daily driving. You get all the handling benefits of a wider track without wrecking your wheel bearings. It is a precise, calculated fitment that shows the owner did their homework.
What We Recommend for Audi S4 B9 Owners
If you want to replicate this look, stick to a 20x9.5 square setup. A 20x9 is fine, but it lacks the concave punch that makes the B9 look truly wide and grounded. We find an offset in the ET35 to ET40 range keeps everything tucked safe under the factory fenders.
Don't even think about a staggered setup on this Quattro system. You will ruin the differential math and trigger every electronic nanny in the dash. Keep the tire diameter identical on all four corners to keep the drivetrain happy.
Tire choice matters as much as the wheel itself. We suggest a 265/30/20 tire for this width to get a clean, vertical sidewall. Avoid the "stretched tire" craze unless you want to ruin your ride quality and curb your expensive forged wheels.
Many owners make the mistake of buying wheels that are too narrow or use cheap spacers to force fitment. Never rely on spacers if you can buy the correct offset from the start. Forgeline builds these to order, so get your specs right before you pull the trigger.
If you are lowered on springs, keep an eye on your camber settings. The B9 has a sensitive suspension geometry that changes quickly with height adjustments. Get a professional alignment immediately after you bolt these on, or you will torch your tires in a thousand miles.
Style and Build Analysis
The choice of Metallic Silver on a silver car is a bold move that pays off in spades. Most people go for black wheels, but they just disappear into the shadows. This monochromatic theme highlights the intricate, aggressive spoke pattern of the VV1R.
The silver-on-silver aesthetic gives the car a clean, polished, and purposeful vibe. It looks like something Audi’s own RS department would have developed as a special edition. It is subtle, classy, and commands attention without being loud or obnoxious.
The proportions are spot on because the 20-inch wheels fill the wheel wells perfectly. Many 19-inch setups look small on the B9 because the body lines are so bulky and muscular. These wheels bring the whole car together and make it look visually lighter.
When the sun hits the metallic finish, the wheels pop against the body paint. You can see the depth in the spokes and the craftsmanship of the forged aluminum. It is a world of difference compared to the flat, matte grey finishes everyone else is rocking.
This build proves that you do not need bright colors or wild body kits to stand out. It is all about the quality of the finish and the precision of the fitment. It is a masterclass in how to upgrade an Audi while keeping its sophisticated soul intact.
Why We Love This Build
I cannot stop looking at how these wheels catch the light as the car rolls through the lot. The Metallic Silver finish against the factory paint creates a unified, high-end look that feels like a factory prototype. It is the perfect blend of luxury and raw, track-ready aggression.
This B9 S4 is exactly how I would build my own car if I had it in the garage today. Every time I see it, I am reminded that simplicity and high-quality parts always beat flashy trends. The fitment is tight, the stance is aggressive, and the vibe is pure class.
This is the benchmark for how an Audi should sit. Go get yourself a set of Forgelines and transform your daily driver into a legend.

Additional Build Info:
Frankenwagon. The slammed stance of Chris Mentrup’s Audi Allroad wagon might be your first clue that there is something different about it. In fact, Chris combined the remains of a wrecked Audi S4 into a full conversion, including drivetrain, brakes, and interior. It rides on Air Lift Performance suspension and 20×9.5 Forgeline one piece forged monoblock VV1R wheels finished in Metallic Silver with the optional Carbon Fiber Center Caps!

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 20×9.5-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 20×9.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
