What is a sleeper build?

A sleeper build is a type of car customization that involves giving the appearance of a stock or unassuming vehicle while modifying the engine and performance components for increased power and speed. The goal of a sleeper build is to surprise and outperform other cars on the road that may underestimate the vehicle's capabilities.

Common modifications in a sleeper build include upgrading the engine, adding a turbocharger or supercharger, installing high-performance exhaust systems, upgrading the suspension and brakes, and tweaking the fuel and ignition systems for better performance. Visual modifications are kept to a minimum to maintain the plain or unassuming appearance of the vehicle.

Sleeper builds are popular among car enthusiasts who enjoy the element of surprise and enjoy the thrill of outperforming more flashy or expensive cars on the road. These builds often require careful planning and expertise to ensure that the modified components work together seamlessly to deliver optimal performance without compromising the vehicle's ability to blend in with traffic.
