About This Porsche 911 GT2 991 Build
We love featuring real builds from real owners. This Black Porsche 911 GT2 991 sits on a set of 20×9.5 and 20×12.5-inch ADV.1 ADV10 TRACK SPEC CS wheels, and the result speaks for itself.
The owner chose ADV.1 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 GT2 builds come through WheelFront every month, but this one stands out. The combination of the Black exterior with the ADV.1 ADV10 TRACK SPEC CS creates a look that balances aggression with elegance.

Fitment Breakdown: ADV.1 ADV10 TRACK SPEC CS on the Porsche 911 GT2 991
I walked around this 991 GT2 for twenty minutes just staring at the fitment. These ADV.1 ADV10 Track Spec CS wheels measure 20x9.5 in the front and 20x12.5 in the rear. That extra width out back fills those massive GT2 rear arches perfectly.
The offsets here are absolute perfection for this specific chassis. We see zero poke and the tires sit flush with the fender line. It creates that aggressive, purposeful stance that every GT-car needs.
Clearance around those massive PCCB calipers is tight but safe. ADV.1 engineered these barrels specifically to avoid any contact with the carbon ceramic hardware. You cannot afford even a millimeter of error on a car with this much stopping power.
The hub bore sits perfectly snug against the Porsche center lock hubs. We hate using hub rings on cars that see high track speeds. These wheels slide on with zero play and lock down tight.
Look at the depth on those rear lips. The Track Spec CS design offers a deep, stepped-lip profile that adds serious drama to the side profile. It highlights the aggressive track width of the GT2 platform.
The spoke design pulls the eye toward the center lock nut. It gives the car a racing pedigree that factory wheels often lack. Everything about this geometry says functional performance.
We checked the inner fender liners for signs of rubbing. Even under heavy compression, the tires clear the arch liners without issue. This is how you build a street-legal track weapon.
What We Recommend for Porsche 911 GT2 991 Owners
Don't mess with the 20-inch diameter if you want to keep the factory handling balance. We find that 20s offer the best compromise between tire sidewall support and aesthetic impact. Stick to the staggered 9.5 and 12.5 width combo for maximum grip.
Finding the right offset is the biggest mistake most owners make. If you go too aggressive, you will destroy your rear fenders during hard cornering. Trust the engineers at ADV.1 to dial in the offset for your specific alignment specs.
Tire selection matters just as much as the wheel choice. We recommend a high-performance tire like a Michelin Pilot Sport Cup 2 to match the GT2 personality. Don't cheap out on rubber when you have this much power hitting the pavement.

Ignore the urge to use wheel spacers on a custom set of forged wheels. Spacers introduce unnecessary vibration and change your scrub radius for the worse. Order your wheels with the correct offset from day one.
Watch your alignment settings closely if you lower the car on aftermarket springs. Adding too much negative camber will ruin your tire life in under three thousand miles. Find a middle ground between track performance and street comfort.
Style and Build Analysis
The Brushed Matte Cognac finish is a bold choice on a black car. Most people go for silver or satin black, but this warm brown tone pops against the dark paint. It looks sophisticated in the shade and glows like copper in direct sunlight.
The black body absorbs the light, while the wheels catch every single ray. This contrast makes the car look wider and lower than a stock unit. It breaks up the dark silhouette in the best way possible.
We have seen hundreds of 991 builds, but this one feels different. The spokes on the ADV10 design are thin enough to look light but thick enough to look strong. It gives the car a mechanical, industrial aesthetic that fits the GT2 vibe.
Proportion is everything when you modify a 911. The 12.5-inch rear wheels make the car look like it has a massive footprint. It screams performance before you even turn the key.
This build proves that you do not need a crazy body kit to stand out. A simple, well-executed wheel setup changes the entire personality of the machine. It is clean, purposeful, and absolutely menacing.
Why We Love This Build
Seeing this car in person changed how I think about custom wheels. The way the Cognac finish catches the afternoon sun against the deep black paint is pure art. It turns a factory beast into a one-of-a-kind masterpiece.
Every time the owner rolls into the lot, heads snap toward the fender wells. The wheels look like they were carved out of solid blocks of metal just for this chassis. It is the perfect marriage of luxury color and raw, track-focused design.
This is the kind of build that makes you want to empty your savings account. It reminds us why we fell in love with car culture in the first place. You need this setup.

Before You Buy: Fitment Checklist

We talk to Porsche 911 GT2 owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 20×9.5 and 20×12.5-inch wheels fit my Porsche 911 GT2? 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 GT2 owners run 20×9.5 and 20×12.5-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
