About This Porsche 911 GT3 RS 991 Build
We love featuring real builds from real owners. This Green Porsche 911 GT3 RS 991 sits on a set of 19×10 and 19×13-inch BBS E88 wheels, and the result speaks for itself.
The owner chose BBS 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 GT3 RS builds come through WheelFront every month, but this one stands out. The combination of the Green exterior with the BBS E88 creates a look that balances aggression with elegance.
Fitment Breakdown: BBS E88 on the Porsche 911 GT3 RS 991
I walked up to this build and immediately noticed how the 19-inch E88s transform the 991 GT3 RS. Dropping from the factory 20/21 setup to a 19-inch square-ish staggered profile changes the entire personality of the car. The 19x10 front and 19x13 rear fitment is aggressive, but it clears the massive PCCB calipers without issue.
The offset on these barrels sits perfectly flush with the factory fenders. You get that meaty, track-ready look that the stock wheels often miss. The hub bore matches the Porsche center lock setup precisely, so you get zero vibration at triple-digit speeds.
Those 19x13 rears are absolute monsters. They tuck deep into the wheel well while the outer lip sits right at the edge of the quarter panel. The spoke design of the E88 provides incredible structural rigidity, which is vital when you are pushing that much rubber into the pavement.
We checked the inner clearance against the rear suspension uprights. There is just enough room to prevent rubbing during high-G cornering loads. You have to be careful with your alignment specs, though, or you might kiss the plastic liners.
The front 19x10 setup allows for a significant amount of steering precision. By downsizing the diameter, we reduced rotational mass, which makes the front end feel sharper. You feel every ounce of grip through the steering wheel.
Because the GT3 RS has such wide hips, the deep lip on the rear BBS wheels really pops. It highlights the muscular stance of the 991 platform. Most people run 20s, but this 19-inch choice shows you actually drive this thing hard.
If you track your car, this specific fitment is a dream. The sidewall of the 265/35 front and 345/30 rear tires provides just the right amount of flex. It keeps the chassis predictable when you are right at the limit.
What We Recommend for Porsche 911 GT3 RS 991 Owners
If you want to replicate this look, stick to the 19-inch diameter for the best performance gains. Going larger usually just adds unsprung weight, which hurts your dampers. We always suggest staying within these specific width ranges to keep the handling balance neutral.
Watch your offsets carefully when ordering custom E88s. Too aggressive and you will destroy your paint on the rear fenders. Aim for a fitment that leaves a few millimeters of clearance for tire expansion under heat.
Avoid running spacers if you can help it. The E88 is a modular wheel, so you should build the centers and barrels to the exact offset you need. It looks cleaner and runs safer at the track.
Tire selection is just as important as the wheel choice. This setup uses a 345 rear which is massive, so choose a tire with a stiff sidewall. A soft tire will feel sloppy on a car with this much downforce.
Don't make the mistake of choosing a finish that hides the detail of the E88 spokes. The Satin Black finish works here because it grounds the bright Green paint. It keeps the aesthetic purposeful rather than flashy.
Check your alignment after install. You will likely need a bit more negative camber to tuck these wide tires properly. A professional corner balance will make this car feel like a factory Cup car.
Style and Build Analysis
The contrast between the Green body and the Satin Black E88s is pure automotive theater. Most people would pick silver or gold, but the black keeps the focus on the car’s aggressive aero. It looks like a GT3 R race car that escaped the paddock.
The BBS E88 design is timeless for a reason. Those intricate, overlapping spokes create a visual texture that modern wheels just cannot match. They look equally at home on a classic air-cooled 911 or this modern water-cooled beast.
The stance is undeniably perfect. The car sits low and wide, with the 345-section rear tires filling out the arches completely. It looks like it is clawing at the asphalt even when it is parked.
We have seen plenty of GT3 RS builds, but this one feels cohesive. Nothing looks forced or over-the-top. The wheels complement the aggressive carbon fiber wings and vents without competing for attention.
Proportions are everything on a 911. By sizing down the wheels, the owner has given the car more sidewall, which makes the whole package look more purposeful. It feels like a real machine rather than a show queen.
Why We Love This Build
This Green 911 GT3 RS with Satin Black E88s captures exactly what a Porsche should be. When the sun hits that green paint, the car glows, and the dark wheels provide a perfect, heavy anchor for the design. We love how it balances raw track aggression with a clean, understated finish.
Every time we see this car, it reminds us why the 991 chassis is a future legend. The wide rubber tucked under those massive fenders makes the car look like a predator ready to pounce. It is the kind of build that makes you want to drop everything and go hit the nearest canyon road.
Stop overthinking your wheel choice and just build this exact setup.

Before You Buy: Fitment Checklist
We talk to Porsche 911 GT3 RS owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 19×10 and 19×13-inch wheels fit my Porsche 911 GT3 RS? 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 GT3 RS owners run 19×10 and 19×13-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
