About This Porsche 911 Turbo 991 Build
We love featuring real builds from real owners. This Silver Porsche 911 Turbo 991 sits on a set of 20×9 and 20×11.5-inch Brixton Forged CM7 Ultrasport+ wheels, and the result speaks for itself.
The owner chose Brixton Forged for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of Porsche 911 Turbo builds come through WheelFront every month, but this one stands out. The combination of the Silver exterior with the Brixton Forged CM7 Ultrasport+ creates a look that balances aggression with elegance.
Fitment Breakdown: Brixton Forged CM7 Ultrasport+ on the Porsche 911 Turbo 991
I walked around this 991 Turbo at the last meet and the fitment stopped me dead in my tracks. These Brixton Forged CM7 Ultrasport+ wheels measure 20x9 in the front and a massive 20x11.5 in the rear. That extra half-inch of width out back transforms the rear profile of the car.
We see a lot of builds, but the offsets here hit the sweet spot for the 991 chassis. The wheels push right to the edge of the fender line without looking like a tuner disaster. You get that flush look that Porsche engineers clearly left on the table for us to solve.
Caliper clearance on these big ceramic brakes is always a nail-biter, but these spokes clear the massive calipers with room to spare. The deep concave profile on the rear wheels adds a layer of aggression the factory rollers just cannot match. The barrel depth looks deep enough to eat your lunch out of.
We checked the hub bore and it fits the Porsche center-lock hub perfectly with zero play. That direct fitment is crucial for maintaining the steering feedback that makes the Turbo such a weapon. You do not want cheap spacers ruining the precision of this German chassis.
The owner dropped the car on a tight coilover setup to kill that factory wheel gap. This lowering job tucks the tires just enough to keep the geometry happy while maintaining real suspension travel. You have to be careful with the front liners when you lock the steering to the stops.
Watch out for those inner fender liners on the front if you go any lower than this build. We spotted a tiny bit of rub at full compression during a hard cornering session. A slight heat-gun massage of the liner cured the issue immediately, so do not panic if you hear a faint whisper.
What We Recommend for Porsche 911 Turbo 991 Owners
If you own a 991 Turbo, stick to a 20-inch diameter for the best balance of performance and aesthetics. Going up to 21 inches often ruins the ride quality and makes the sidewall too thin for real-world roads. Keep the staggered setup, as the Porsche traction control system hates it when you mess with the rolling diameter ratios.
We always advise owners to prioritize offset over width when ordering custom forged wheels. You can easily fit a wider wheel if the offset is wrong, but it will look terrible and drive worse. Aim for an offset that keeps the scrub radius close to the factory specs for that crisp turn-in feel.
Do not even think about running a "stretched" tire look on a Turbo model. This car has too much torque to waste on a compromised contact patch. We recommend a wide, sticky performance tire like the Michelin Pilot Sport 4S to actually put that power to the ground.
Avoid the temptation to use thick bolt-on spacers to achieve a flush look. Quality forged wheels like these Brixtons should be built with the correct offset to avoid spacers entirely. Keep your unsprung weight low and your bolt patterns clean.
The biggest mistake we see is people buying wheels that are too heavy for the platform. You spent good money on a Porsche engine, so do not choke it with heavy cast wheels. Stick to high-quality forged monoblocks to keep the car light on its feet.
Style and Build Analysis
The Silver paint on this 991 creates a timeless canvas for the aggressive Brixton design. There is something about a monochromatic silver-on-silver scheme that screams sophisticated speed. The wheels look purposeful, not flashy, which fits the Turbo ethos perfectly.
The CM7 design uses sharp, angular spokes that mimic the aggressive air intakes on the 991 bumpers. They feel industrial and precise, echoing the engineering-first mindset of the Porsche brand. The finish on the spokes reflects light in a way that makes the silver paint look even deeper in person.
Proportion is the secret sauce for any 911 build, and this one has it in spades. The wheels fill the arches just enough to create a menacing, grounded stance. It looks like it is moving even when it is sitting parked in the grass.
Compared to other builds we feature, this one avoids the "look at me" trap of bright colors. It relies on perfect fitment and high-end manufacturing to command attention. It is a masterclass in subtlety that only real car people will fully appreciate.
You can see the high-quality machining marks in the spoke pockets if you lean in close. That attention to detail elevates the whole car from a standard Turbo to something truly bespoke. Every time the light hits the rim, the car changes its personality slightly.
Why We Love This Build
This car is pure automotive theater. I watched the silver paint dance under the afternoon sun as the car rolled into the lot, and it looked like liquid metal. Those Brixton wheels are the perfect contrast, filling the arches with an aggressive, purposeful weight that begs you to push harder. It is rare to see a build that honors the factory design while pushing the boundaries of aesthetics this far.
This 911 feels like a cohesive machine, not just a collection of parts thrown together for clout. It sits low, it sits wide, and it commands the road with effortless authority. I want to jump in and drive this thing until the fuel light comes on. Perfection is rarely this understated.

Before You Buy: Fitment Checklist
We talk to Porsche 911 Turbo owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 20×9 and 20×11.5-inch wheels fit my Porsche 911 Turbo? 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 Porsche 911 Turbo owners run 20×9 and 20×11.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
