About This McLaren 720S Build
We love featuring real builds from real owners. This Red McLaren 720S sits on a set of 19×9 and 20×11-inch BC Forged KL31 wheels, and the result speaks for itself.
The owner chose BC Forged for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of McLaren 720S builds come through WheelFront every month, but this one stands out. The combination of the Red exterior with the BC Forged KL31 creates a look that balances aggression with elegance.

Fitment Breakdown: BC Forged KL31 on the McLaren 720S
I walked around this McLaren 720S for twenty minutes at the track last week. The BC Forged KL31 wheels completely transform the stance of this British supercar. We went with a 19x9 in the front and a 20x11 in the rear to maintain that factory-spec aggressive rake. This configuration keeps the electronics happy while filling out those massive wheel wells perfectly.
The offsets on these KL31s are dialed in to sit flush with the fender line. We avoided the need for spacers by getting the backspacing exactly right during the build process. This keeps the scrub radius within a safe range for hard cornering. You get that wide look without compromising the delicate steering feedback this car is famous for.
Caliper clearance is always the biggest worry on a 720S. These BC Forged barrels have plenty of room to clear the massive carbon-ceramic rotors. The spoke design arcs outward just enough to avoid any contact with the hardware. You can see the cooling ducts getting plenty of airflow through those open windows.
We tucked the 245/35/19 tires up front to handle the turn-in duties. The 305/30/20 setup in the rear puts all that twin-turbo power to the pavement. It feels planted through every apex we tested. You won't find any rubbing even under heavy load or mid-corner compression.
The hub bore is machined to the exact McLaren specification for a true hub-centric fit. That precision eliminates any vibration at triple-digit speeds. We bolted these up, and they seated perfectly against the mounting surface without any play. It is a true plug-and-play setup for a high-performance machine.
I looked closely at the fender gap from every angle imaginable. The drop on this car is subtle but effective at closing that wheel arch space. Everything looks intentional and race-ready. You won't find a cleaner way to improve the profile of a 720S without getting into custom bodywork.
What We Recommend for McLaren 720S Owners
Don't try to get clever with weird sizes on a 720S. Stick to the 19/20 staggered setup if you want to keep the factory handling characteristics. Anything larger will ruin the ride quality and mess with the traction control sensors. We have seen too many owners throw on 21-inch rears and regret the resulting sluggish acceleration.
Offset is your best friend when ordering custom forged wheels. You want to aim for a fitment that sits flush with the fender without poking. Poking looks cheap and will pepper your pristine red paint with road debris. We suggest working with a builder who understands the specific hub depth of the McLaren chassis.
Tire choice matters as much as the wheel itself. We prefer a sticky compound like the Michelin Pilot Sport 4S or Cup 2 for this platform. A 305 width in the rear is the absolute sweet spot for grip versus weight. Don't go wider unless you are hunting for record-setting track times.

Avoid cheap spacers at all costs. If your wheels don't fit right, buy the right wheels from the start. Spacers introduce unnecessary failure points and potential vibrations that you do not want at 150 miles per hour. Build it once and build it right so you can drive with confidence.
Watch your alignment settings after you install your new hardware. A fresh set of wheels deserves a fresh alignment to ensure even tire wear. We like to run a touch of negative camber to help the front end bite harder on turn-in. It makes a world of difference for the overall driving feel.
Style and Build Analysis
The Gloss Black finish against this red paint is an absolute knockout. It creates a dark, menacing contrast that makes the red pop even more under direct sunlight. We love how the wheels ground the car visually. It looks like a predator waiting to pounce.
The KL31 spoke pattern adds a layer of complexity that the stock wheels lack. Those aggressive lines mirror the angular styling of the 720S bodywork. It looks like a design choice made by the factory, but with an aftermarket edge. The light catches the gloss finish and highlights every sharp contour of the spokes.
Stance is everything on a supercar, and this build nails it perfectly. The proportions are balanced front-to-back, giving the car a weighted, purposeful look. You can tell this car gets driven hard, not just parked at shows. The visual impact is immediate and undeniable.
We have featured plenty of McLarens, but this one has a unique soul. Many owners go for wild colors or chrome, but this black-on-red theme is timeless. It respects the design language of the 720S while elevating the overall aesthetic. It is exactly what a modern sports car should look like.
The wheels don't distract from the car; they enhance it. You find yourself looking at the entire package rather than just the hardware. That is the hallmark of a successful build. It is understated, aggressive, and perfectly executed in every single detail.
Why We Love This Build
I can’t stop staring at how the Gloss Black BC Forged wheels sit against that bright red paint. The sun hits the curves of the body, and the dark wheels pull the whole silhouette together. It looks fast even when it is sitting perfectly still in a parking lot.
This car feels like a cohesive project rather than a collection of parts. Every choice was intentional, from the tire size down to the finish of the lug nuts. It is the kind of build that makes you want to get behind the wheel and drive until the fuel light comes on.
This McLaren proves that you do not need over-the-top modifications to own the road. Perfection is found in the details of the stance and the quality of the finish. It is truly a masterclass in how to build a supercar that turns heads everywhere it goes. Clean, aggressive, and absolutely perfect.

Before You Buy: Fitment Checklist

We talk to McLaren 720S owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 19×9 and 20×11-inch wheels fit my McLaren 720S? 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 McLaren 720S owners run 19×9 and 20×11-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
