Our brake kits, including caliper finishes, rotor details, hardware, and pre-shipment packed sets.
The listed price is for the front iron big brake kit only. A matching rear axle kit is also available upon request.
All components can be customized at an additional cost, with options including different rotor sizes, caliper sizes, and piston counts to match different performance goals and budgets. In most cases, kits are in stock and ready to ship within 7 days.
Base Configuration Note
The listed price is based on our most commonly requested front upgrade: 6-piston calipers paired with 380 mm rotors. We use this setup as the standard starting point because, in most cases, it offers the best balance of braking performance, daily usability, wheel fitment, and overall value. The 380 mm size is a practical middle ground that delivers a strong upgrade over many factory OE brake systems without typically requiring very large wheels.
This base setup is shown for pricing clarity, but our goal is not to sell every customer the exact same kit. We discuss how the car is actually used, whether it is mainly street-driven, occasionally driven hard, or regularly used on track, and then recommend the most suitable configuration for that use and budget.
For example, not every driver needs aggressive high-noise brake pads intended for track-focused performance. For many street cars, a lower-noise pad with better comfort and strong everyday braking performance is the better choice. We can also tailor rotor size, caliper style, pad compound, and other components to build the most appropriate upgrade for each customer.
Shipping to the customer is not included in the price & quoted separately based on destination and delivery method. We can offer:
Reference sizes are provided as a baseline and reflect the most common OEM setup. The table below is for dimension reference only. Because rotor dimensions can vary by trim, market, or prior brake changes, the final build is confirmed from verified measurements.
| Chassis | Type | Front | Rear |

| 2023+ (G07) | Iron | 395x36 mm | 398x28 mm |
If you are investing in both forged wheels and a serious brake upgrade, you are already in the right place. Within Forza Performance Group, forged wheels and big brake solutions are not treated as unrelated parts sourced from different directions—they are developed within one ecosystem, allowing us to engineer the complete package as one matched solution. That gives you more than attractive bundle pricing: it gives you one source responsible for how the entire system fits, looks, and performs.
Each wheel is tailored around the upgraded brake system to achieve the exact caliper clearance, spoke curvature, X-factor, and inner barrel geometry required for your vehicle. Instead of leaving fitment to trial and error, we resolve the critical details before production, so the final package arrives with the proportions, presence, and technical integrity a serious build deserves. The result is no guesswork, no visual compromise, and no expensive surprises—just a brake-and-wheel package that installs cleanly, looks intentional, and performs exactly as a properly engineered build should, with OE TPMS and factory hardware compatibility available on request.
Quick takeaways first. Full technical details are available below.
The BMW X7 M60i G07 (2023+) iron Big Brake Kit is built around a practical upgrade goal: more thermal capacity and firmer braking response without turning the car into a fragile race-only setup. That balance matters on a vehicle-specific platform, where the best result comes from matching rotor dimensions, caliper geometry, and wheel clearance to the exact chassis.
On a vehicle-specific platform, the best BBK setup should feel controlled during normal driving and more stable during heavier braking. That means avoiding an oversized-only approach and keeping pad behavior, rotor mass, and hydraulic feel in balance.
Rotor and caliper size set the hardware foundation, but pad compound decides bite, noise, dust, and temperature behavior. A street/performance pad choice is usually the right starting point unless the vehicle is being prepared for dedicated track use.
The listed brake envelope uses 395x36 front and 398x28 rear rotor dimensions. A larger iron rotor can absorb more heat during repeated braking and gives the pad a broader working surface, which is useful when the factory setup feels thermally limited.
The caliper is only effective when its bracket position, pad sweep, and rotor ring geometry are matched correctly. For BMW X7 M60i G07 (2023+), this is why chassis-level fitment matters more than a generic diameter claim.
A BBK can improve confidence only when hydraulic response is controlled. Stainless brake hoses, fresh fluid, and correct bleeding help the upgraded calipers translate pedal input into repeatable pressure at the pads.
For BMW X7 M60i G07 (2023+), the safest BBK selection process is to validate the fitment data first, then choose caliper and pad specification around the intended use. That keeps the upgrade focused on real braking behavior, not only appearance.
