About This Audi S5 B9 Build
We love featuring real builds from real owners. This Green Audi S5 B9 sits on a set of 20×10-inch Blaque Diamond BD-27 wheels, and the result speaks for itself.
The owner chose Blaque Diamond for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of Audi S5 builds come through WheelFront every month, but this one stands out. The combination of the Green exterior with the Blaque Diamond BD-27 creates a look that balances aggression with elegance.
Fitment Breakdown: Blaque Diamond BD-27 on the Audi S5 B9
I walked around this B9 S5 for an hour at the show, and the fitment is spot on. We are looking at a 20x10 setup that fills those arches perfectly. The width pushes right to the edge without looking like a circus wagon.
The offset on these Blaque Diamond BD-27s keeps the wheel face tucked just enough to avoid that ugly poke. We checked the hub bore closely, and the direct fitment eliminates the need for annoying rings. You get a clean, hub-centric setup that rolls smooth at high speeds.
Caliper clearance on the big Audi brakes is always a concern with aftermarket wheels. These BD-27s clear the front calipers with room to spare, so you won't need spacers. That spoke design creates enough concave depth to clear the hardware while keeping the weight balanced.
The barrel lip depth gives the car a serious, aggressive edge. You can see how the design draws your eye straight to the center caps. It’s a bold look that doesn't feel forced or overdone.
We noticed this car is sitting on lowering springs, which tightens up the fender gap significantly. That drop is the secret sauce for making a 20-inch wheel look this good. Without the drop, you might see a bit too much daylight between the tire and the fender liner.
Watch out for rubbing if you carry passengers in the back. The inner liner on the B9 is tight, and a 10-inch wide wheel leaves very little margin for error. If you go too wide on the tires, expect to trim the plastic tabs.
What We Recommend for Audi S5 B9 Owners
Stick to a 20x10 or 20x9.5 for the best visual impact on the B9 platform. Anything narrower looks sunken, while going wider creates a nightmare for your alignment shop. We have tested these ranges extensively, and this is the sweet spot.
For offsets, keep your numbers between ET25 and ET30. This range ensures the wheel sits flush with the fender line. If you go lower than ET25, you are asking for rubbing issues on every bump you hit.
We always suggest a square setup for these cars. It makes rotating your tires easy and keeps the Quattro system happy. Staggered setups look cool, but they often mess with the sensitive Audi traction control sensors.
Don't fall into the trap of buying cheap, heavy wheels just for the look. These BD-27s offer a great balance of strength and weight. Cheap wheels bend the second you hit a pothole, and nobody wants that headache.
When picking tires, aim for a 265/30/20 setup. This gives you just enough sidewall to protect your rim while maintaining that sleek, low-profile look. A slight stretch can help with clearance, but don't go overboard unless you want to blow a bead.
Style and Build Analysis
The Silver finish against that deep Green paint is a masterclass in classic styling. Most guys go for black wheels, but this Silver choice pops in the sunlight. It provides a crisp, metallic contrast that highlights the complex design of the BD-27 spokes.
The wheel design itself is sharp and modern, matching the crisp body lines of the B9. It doesn't look like a copycat wheel. The directional flow of the spokes gives the car a sense of speed even when it's parked.
Stance is everything with an Audi, and this build nails it. The wheels look like they belong on the car from the factory, but with more attitude. You get that OEM-plus vibe that turns heads without screaming for attention.
Compared to other builds, this one feels intentional. We have seen plenty of S5s with bad offsets and cheap tires, but this setup shows restraint. It feels like a cohesive package rather than a collection of random parts.
The proportions are perfect, balancing the heavy front end of the Audi with the lightweight look of the wheels. Every detail, from the color choice to the fitment, works in harmony. It’s a build we keep coming back to for inspiration.
Why We Love This Build
This green S5 looks like a predator waiting to pounce on the asphalt. The way the Silver BD-27s catch the light makes the whole car look fast just sitting still. We love how the wheels fill the arches without destroying the clean lines of the Audi design.
Seeing a build this dialed in makes you want to go straight to the garage and order a set. It captures the spirit of what we do here at WheelFront. You get the perfect mix of luxury and performance in one stunning package.
This car is a reminder that the right set of wheels changes everything. Go find your own fitment and make your car look this good.

Before You Buy: Fitment Checklist
We talk to Audi S5 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 S5? 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 S5 owners run 20×10-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
