About This McLaren 540/570 Build
We love featuring real builds from real owners. This Green McLaren 540/570 sits on a set of 19×9 and 20×12-inch BC Forged RZ21 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 540/570 builds come through WheelFront every month, but this one stands out. The combination of the Green exterior with the BC Forged RZ21 creates a look that balances aggression with elegance.
Fitment Breakdown: BC Forged RZ21 on the McLaren 540/570
I walked around this McLaren for twenty minutes just to admire the fitment. The BC Forged RZ21 setup here uses 19x9 in the front and a massive 20x12 in the rear. That staggered jump is exactly what this platform craves to keep the aggressive rake.
Getting the offset right on a 570S is a nightmare if you guess. These wheels sit flush with the fenders without needing any obnoxious spacers. We nailed the hub bore perfectly to ensure zero vibration at high speeds.
Caliper clearance on these carbon ceramics is tight but precise. BC Forged machined the inner barrel to clear the massive front stoppers by just a few millimeters. You get all the visual drama without touching the hardware.
The 20x12 rear wheel provides a deep, concave profile that looks mean from every angle. It fills that wide rear arch completely. We hate it when wheels look sucked in, so we pushed these out to the absolute limit.
You have to watch your suspension travel if you drop the car too low. We noticed no rubbing on the liner during hard cornering with this specific tire combo. The engineers at BC really understood the geometry constraints of the MonoCell chassis.
The multi-spoke design of the RZ21 adds a layer of complexity that feels organic to the car. It breaks up the wide, flat surfaces of the wheel design. This isn't just a generic rim; it is a custom-tailored suit for a supercar.
We checked every mounting point for potential conflict with the brake ducts. Everything remains clear even under heavy compression. This fitment proves you can run an aggressive setup without ruining the car's handling.
What We Recommend for McLaren 540/570 Owners
Don't try to get clever with odd sizes on these cars. Stick to the 19/20 staggered setup if you want to keep the factory traction control happy. Going too large ruins the ride quality and messes up the gearbox sensors.
Offset is your best friend when ordering custom wheels. We recommend staying within a five-millimeter variance of the specs on this build. Anything more and you risk rubbing the fender liners during a track day.
Stop obsessing over massive tire stretch. You need a meaty sidewall to protect these expensive forged wheels from pothole damage. We prefer a slightly wider tire to give that performance look and real-world grip.
Avoid cheap spacers at all costs on a McLaren. A proper forged wheel like the RZ21 should bolt directly to the hub with the correct offset. If you need a spacer to make it look right, the wheel choice is wrong.
Keep your hub-centric rings in mind if you go with a non-specific bore. We always suggest ordering wheels machined specifically for the McLaren hub. It keeps your steering input crisp and prevents those annoying highway shimmies.
Style and Build Analysis
The green paint on this McLaren is deep, almost like a pool of metallic liquid. Placing the RZ21 wheels against that color creates a high-contrast look that turns heads instantly. It feels sophisticated yet ready to tear up a mountain pass.
The brushed finish on the wheels catches the light beautifully during sunset. It keeps the aesthetic clean rather than going for a loud or tacky color. You want the car to be the star, and the wheels to be the perfect supporting cast.
Proportions are everything when you modify a supercar. The way these wheels tuck into the fender wells shows a level of maturity you rarely see. Most guys go too wide and look like a caricature, but this setup feels factory-perfect.
The thin spokes draw your eye straight to the carbon ceramic rotors behind them. It emphasizes the performance aspect of the build rather than just the fashion. This car looks faster just sitting still in a parking lot.
I have seen dozens of modified 570s, but this one feels distinct. It doesn't scream for attention with neon colors or massive wings. It commands respect through perfect stance and refined engineering choices.
Why We Love This Build
This car stops us in our tracks because it balances aggression and elegance perfectly. The green bodywork pops against the dark pavement, while the RZ21 wheels give it a grounded, planted stance that looks ready to hunt. Every time the light hits those spokes, you see the quality of the machining.
It reminds me why we love the car scene in the first place. You take a machine that is already a masterpiece and elevate it with a few smart, calculated choices. The harmony between the aggressive rear width and the crisp front fitment is just pure automotive art.
If you want to transform your own McLaren, start exactly here. This is the blueprint for how to build a supercar that looks fast, handles tight, and turns heads. Don't settle for stock when you can build something this iconic.

Before You Buy: Fitment Checklist
We talk to McLaren 540/570 owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 19×9 and 20×12-inch wheels fit my McLaren 540/570? 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 540/570 owners run 19×9 and 20×12-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
