144: Is a Retired F1 Car the Ultimate Track Toy?

No matter the stage of a build, most projects reach a point where giving up feels tempting. They demand grit and perseverance—and Karel Silha from Karel S Motorsport’s wild DTM-inspired M4 Time Attack build is no exception.

We first spoke to Karel in 2022, and now he’s back to share what it really takes to shake down and test a home-built car of this caliber. Believe it or not, it all started with a toy car that Karel scanned and scaled up using CAD

In this episode, we explore the engineering details behind the build. Karel explains the challenges of mounting a massive aero package capable of generating serious downforce. He highlights the practical difficulties of high-performance engineering in a garage environment.

Karel also shares how he’s utilised modern tools like CAD and FEA to optimise the design. We talk through his experience testing on KW Suspension’s seven-post rig—fine-tuning the suspension for low-speed mechanical grip and managing the immense downforce at high speeds.

We discuss the complexities of engine management with turbocharging and individual throttle bodies (ITBs), the importance of on track testing versus dyno calibration.

Despite the technical challenges and the emotional toll, this episode is far from bleak. Karel’s journey is incredibly inspiring and he’s optimistic that 2025 will finally be the year this insane build shows its true potential.
