About This Audi S4 Premium Plus 2015 Build
We love featuring real builds from real owners. This Audi S4 Premium Plus 2015 sits on a set of 19×9.5 / 19×9.5-inch Rotiform Forged BLQ-T wheels, and the result speaks for itself.
The owner chose Rotiform 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 Premium Plus builds come through WheelFront every month, but this one stands out. The combination of the exterior with the Rotiform Forged BLQ-T creates a look that balances aggression with elegance.
Fitment Breakdown: Rotiform Forged BLQ-T on the Audi S4 Premium Plus 2015
I stood right next to this S4 when it aired out, and the fitment is absolutely spot on. We are looking at a square setup of 19x9.5 Rotiform Forged BLQ-Ts wrapped in those tight arches. Running a 40 offset on all four corners fills the wheel wells perfectly without looking like a tuner disaster.
The B8.5 platform is picky, but this width hits the sweet spot for the fender line. By choosing a 9.5-inch width, we gain that aggressive look while keeping the tire profile manageable. The hub bore matches up precisely, so you get zero vibration at highway speeds.
Caliper clearance is always the nightmare on an S4. These forged BLQ-Ts offer plenty of room for the factory brakes, even with that intricate spoke design. We don't see any rubbing against the hat or the caliper bridge here.
The spoke design pulls the eye right to the center of the wheel. Because these are forged, the barrels are thin but strong, which gives us that extra bit of inner clearance. You won't find any issues with suspension components hitting the barrel on this setup.
Since we are on air suspension, the static clearance rules go out the window when parked. When you air out, the tires tuck just behind the fender lip. It is a masterclass in aggressive yet functional engineering.
Watch out for the inner fender liner if you decide to go any lower than this. We saw the owner trim back the plastic tabs just to be safe. A little bit of heat gun work on the liners goes a long way here.
Everything about this spec screams precision. The 40 offset keeps the wheels tucked enough to avoid destroying your paint on the highway. We love how the wheel face stays flush with the fender edge when the car sits at ride height.
What We Recommend for Audi S4 Premium Plus 2015 Owners
If you want to replicate this look, stick to the 19-inch diameter. Going up to 20s usually ruins the ride quality on these Audis. The 19x9.5 square setup is the gold standard for a reason.
Aim for an offset between 35 and 42. Anything lower than 35 will poke too much and spray rocks all over your doors. Anything higher than 45 will look sunk and get lost in the wheel well.
We always suggest a square setup for the Quattro system. Running different sizes front and back can mess with the center differential over time. Keep the rolling diameter identical to protect your drivetrain.
Don't be afraid of a light tire stretch. It helps with clearance when you air out or run a stiffer coilover setup. A 255/35/19 tire is usually the perfect companion for this width.
Avoid cheap cast wheels if you can swing the budget for forged. The BLQ-T design is heavy on detail, and cheap cast versions are usually a nightmare to balance. Forged wheels keep the unsprung weight low, which keeps the S4 feeling sharp in the corners.
Check your bolts before you hit the road. Many aftermarket wheels require specific ball-seat or cone-seat lugs. Never assume your stock hardware will work with your new high-end wheels.
Style and Build Analysis
The black finish on these BLQ-Ts creates a sinister look that changes with the light. Against the metallic paint of this S4, the wheels practically disappear into the shadows until they start moving. It gives the car a grounded, heavy presence that factory wheels just can't match.
The BLQ-T design is a modern take on a classic multi-spoke geometry. Each spoke creates a unique sense of motion even when the car sits dead still. It looks complex, yet it feels completely at home on the clean lines of the B8.5 body.
This build nails the proportions perfectly. The gap between the spokes shows off the brake hardware, which adds a bit of mechanical texture to the whole package. It feels purposeful, not just flashy for the sake of attention.
We see a lot of Audis running generic deep-dish wheels that look cluttered. This setup is different because the wheels complement the chassis instead of fighting it. It feels like a factory performance package that Audi forgot to offer from the showroom.
The stance is pure aggression. When the air suspension drops the frame, the wheels look like they were carved out of the bodywork itself. It is a cohesive, high-end build that sets the bar for every other S4 at the show.
Why We Love This Build
I walked around this Audi three times just to soak in the details. When the sun hits the black forged finish, the geometry of the BLQ-T pops with an intensity that photos simply miss. It looks fast, mean, and perfectly tuned for the street. The way the arches swallow those wheels when the air bags release is nothing short of art.
We love that the owner didn't overdo it with wild colors or absurd offsets. This build is clean, professional, and undeniably cool. It reminds us why we fell in love with car culture in the first place. You need this setup in your life if you want to turn heads.
Go find a set of these and finish your car right.

Before You Buy: Fitment Checklist
We talk to Audi S4 Premium Plus owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 19×9.5 / 19×9.5-inch wheels fit my Audi S4 Premium Plus? 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 Premium Plus owners run 19×9.5 / 19×9.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
