About This Audi RS5 B9 Build
We love featuring real builds from real owners. This Grey Audi RS5 B9 sits on a set of 20×10.5-inch 305 Forged FT107 wheels, and the result speaks for itself.
The owner chose 305 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 RS5 builds come through WheelFront every month, but this one stands out. The combination of the Grey exterior with the 305 Forged FT107 creates a look that balances aggression with elegance.
Fitment Breakdown: 305 Forged FT107 on the Audi RS5 B9
I walked around this RS5 for an hour at the show, and the fitment is spot on. We are looking at 20x10.5 wheels wrapped in 275/30/20 rubber. This width pushes the wheel right to the edge of the B9 fender without looking like a monster truck.
The 305 Forged FT107 wheels clear those massive factory Audi calipers with room to spare. Many aftermarket wheels struggle with the RS5 brake package, but these barrels give you plenty of breathing space. You will not deal with any annoying interference here.
The offset choice on this build is aggressive enough to look custom but conservative enough to save your paint. We always worry about fender contact on the B9 platform when pushing past 10 inches of width. This setup avoids that nightmare entirely.
Hub bore fitment is perfect, so you do not need any sketchy hub rings to keep things stable. A vibration-free ride is mandatory for a car with this much torque. These wheels lock onto the hub like they came from the factory line.
The spoke design on the FT107 creates a deep, concave profile that really pops in person. It draws your eye straight to the center of the wheel. It makes the car look wider and lower than it actually is.
Because the owner lowered the suspension, the wheel arch gap is basically gone. The tires sit tucked just inside the metal. It is tight, but it works without rubbing on the inner fender liners during hard cornering.
If you run this exact setup, watch out for steep driveways and deep potholes. You have less sidewall than the factory wheels provided. Treat the rims with respect and they will reward you with killer looks.
What We Recommend for Audi RS5 B9 Owners
For the B9 platform, stick to a 20-inch diameter for the best balance of looks and performance. Going up to 21 inches usually ruins the ride quality on these heavy sedans. You want to keep that Quattro grip planted, not bouncing over bumps.
Aim for an offset in the ET25 to ET30 range if you want that flush look. Anything lower than ET25 will likely poke too much and spray rocks all over your quarter panels. We have seen too many guys ruin their paint by going too aggressive.
I highly suggest a square setup for these cars to keep the handling predictable. Staggered widths on an AWD platform like this can mess with the center differential over time. Keep the rolling diameter identical front to rear to save your drivetrain.
The 275/30/20 tire choice on this build is the gold standard for a 10.5-inch wide wheel. It provides just enough stretch to clear the fender while still protecting the rim edge. Do not try to stuff a wider tire on there unless you plan on rolling your fenders.
Avoid cheap spacers at all costs if you want to keep the car's steering feel sharp. Good wheels like these FT107s are engineered to fit correctly without extra junk behind them. Buy it right the first time and save your wheel bearings the headache.
Style and Build Analysis
The Matte Graphite finish against that Grey paint is a masterclass in subtlety. It is not shouting for attention with chrome or bright colors. It demands respect through a monochromatic, tactical aesthetic.
The FT107 design features clean lines that match the sharp edges of the B9 body panels. It looks like an extension of the Audi design language rather than an afterthought. The spokes flow outward with purpose.
Proportionally, the wheels fill the wheel wells perfectly, giving the car a hunkered-down, ready-to-pounce stance. It looks like it is moving even when it is parked at the curb. That is the secret to a great build.
Most builds we see are too loud or too cluttered, but this one remains classy. It keeps the RS5 spirit alive while adding just enough edge to stand out. It is aggressive without being tacky.
I have featured plenty of RS5s, but this one hits the mark on every single detail. It proves that you do not need wild modifications to build a head-turner. You just need the right set of shoes and a good eye for height.
Why We Love This Build
This RS5 build hits me right in the gut every time I see it. The Matte Graphite wheels soak up the light, making the grey paint look even deeper and more aggressive. It sits with a menace that standard RS5s just cannot touch.
We see a lot of cars, but this one feels cohesive and intentional. Everything from the offset to the tire choice works in total harmony. It is the kind of car that makes you look back every single time you walk away.
This is the definitive way to modify a B9. Stop dreaming and go get your fitment dialed in.

Before You Buy: Fitment Checklist
We talk to Audi RS5 owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 20×10.5-inch wheels fit my Audi RS5? 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 RS5 owners run 20×10.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
