A race car is not one thing. It's thousands of things nested inside other things, arranged in a specific order, working in concert, built to a purpose.
Your car is a composition. Your engine is a composition within that composition. Your transmission is another. Your suspension is yet another. Each of those breaks down further into sub-assemblies, into components, into parts. The hierarchical structure of a modern race car is complex, intricate, and—until now—almost impossible to manage digitally in a way that captures reality.
That's what RaceOps Composition was built to solve.
What Is a Composition?
Think of a composition as a living blueprint. It's a complete, hierarchical record of every physical component that makes up your race car at any given moment in time.
Unlike a static spec sheet or a static CAD file, a composition is dynamic. It changes. You modify it. You add components. You remove them. You swap them out. Every change flows through the system, tracked and dated. But the structure—the fundamental hierarchy of how your car is organized—that stays consistent.
Your car composition might look like this:

└── Aerodynamic Package (2026 High Downforce Kit)
Every item in that tree is a component. Some of those components are themselves compositions with their own nested structures. Your engine isn't just "an engine"—it's a collection of assemblies, each of which has specific characteristics, installation dates, and modification history.
Why Hierarchical Structure Matters
A flat list of parts doesn't capture how a race car works. Everything connects. Everything depends on something else.
When your engineer wants to change brake geometry, they need to understand what's installed in the brake system right now, what alternatives will fit, what suspension geometry they're working with, what tire setup they're running. All of that context comes from the hierarchical structure.
RaceOps Composition gives you that context automatically. You're not scrolling through a disconnected parts list. You're looking at your car as an integrated system. You can zoom in on the suspension and see the entire assembly, or zoom out and see how it relates to the engine installation and the aero package.
This is especially critical for nested compositions. Your engine is a complete subsystem with its own component hierarchy. When you swap engines, the entire engine composition comes with it—the new block, the new heads, the new injectors, everything. But your transmission is a separate composition that stays in the car. RaceOps knows which parts are connected, which can move independently, and how modifications cascade through the system.
Adding, Removing, and Swapping
These are the three fundamental operations in any race car build. RaceOps makes all of them traceable.
Adding a component is straightforward. You install new brakes, new springs, a new aero package. You log it in the composition. Date, time, component specification, who did the work. From that moment forward, that component is part of your car's official record.
Removing a component is equally tracked. You take the old engine out. That removal is logged. The component leaves your car composition. You have a record of how long it was installed, when it came out, and the condition it was in.
Swapping is where the power becomes obvious. You swap your transmission for a different one. RaceOps logs it as a removal (old transmission out) and an addition (new transmission in) simultaneously. The system knows you're swapping, not just removing and hoping to remember to add something later. This creates continuity. There's no gap in time where "no transmission" is in your car. There's just a transition point where one transmission left and another arrived.
Every swap, every addition, every removal is a build event. The sum of all those events is your car's complete history.
Visual Build Management
Hierarchical structures are powerful, but they can be complex. That's why RaceOps renders your composition visually. You see your car as an actual diagram. Not a generic diagram—your specific car, with your specific components, organized exactly as they're physically installed.
This visual representation makes it instantly obvious what's on the car, how it's organized, and what the last modification was. You can expand any section to see sub-components. You can inspect individual parts. You can see the complete engine assembly with every component nested inside it.
This is useful for communication, for onboarding new team members, for contractor management. When you're explaining to a new mechanic how the car is configured, you don't have to describe it. You show them the composition. They see it visually, hierarchically organized, with every part labeled and dated.
From Spec Cars to Prototypes
RaceOps Composition works at every scale. A spec car might have 500 parts. A prototype might have 3,000. A factory prototype might have 10,000. The hierarchical structure scales because it's nested. You don't manage 10,000 separate components. You manage a handful of major assemblies, each of which has its own nested structure.
The tier system reflects this:
- Track Day: 5 compositions (perfect for an individual driver or a small spec car team)
- Club: Unlimited compositions (multiple cars, multiple configurations)
- Pro-Am: Unlimited compositions with full forensic history (serious multi-car, multi-series operations)
- Professional: 100 compositions with unlimited forensic history (prototype programs, active development)
- Enterprise: Unlimited everything (factory teams, large operations)
Whether you're managing a single spec car or a fleet of prototypes, the system adapts to your complexity.
See Your Car Like Never Before
This is what separates RaceOps from every other SaaS platform in motorsport. Most systems are designed around lap times, telemetry, or accounting. RaceOps is designed around the actual physical reality of the car—its composition, its evolution, its complete history.
When you build in RaceOps, you're not filling out a form. You're defining your car's actual structure. You're creating a living, breathing digital twin of your vehicle. That twin grows with your team. It evolves. It becomes the single source of truth for what's actually on your race car.
That's revolutionary. That's competitive advantage.
WIN. MORE. RACES.
