BUILT, NOT JUST BOLTED TOGETHER.

A proper performance build is more than a list of parts.

Every component has to work together.

At Sombra Performance, we take the time to understand the goal of the car before putting together the combination. Power level, fuel, turbo sizing, transmission setup, drivetrain, suspension, electronics, and intended use all matter.

Whether the goal is a fast street car, roll-racing setup, drag car, or completely custom project, we focus on building a complete package.

Performance Builds

MULTIPLE PLATFORMS. ONE STANDARD.

Our experience includes BMW performance platforms such as the N54 and B58, high-horsepower turbo applications, LS-powered vehicles, custom swaps, E85 builds, standalone ECU systems, and ZF 8HP drivetrain setups.

We aren't interested in limiting ourselves to one platform.

If it can be made faster, stronger, cleaner, or more capable, we want to build it.

YOUR BUILD. YOUR GOAL.

Some customers want a reliable 500-horsepower street car.

Others want four-digit power.

Some want a car that dominates from a roll.

Others want something built specifically for the drag strip.

Our job is to understand the goal and build the car around it.

No cookie-cutter combinations. No unnecessary parts. No pretending every build needs the same solution.

Just the right setup for the car.

BUILT DIFFERENT. BUILT SOMBRA.
