SPRING STEEL CHASSIS FOR SCHUMACHER Mi9

Engineered from high-grade spring steel and developed through extensive CAD design and track testing, the Schumacher Mi9 chassis plate is built to enhance stability, consistency, and corner speed on medium to high grip tracks.

Compared to the standard carbon chassis, the spring steel version offers a smoother and more linear handling feel, increasing traction and reducing chassis flex-induced snap reactions during direction changes.

Ideal for carpet and asphalt racing, it provides a lower center of gravity and improved weight balance, allowing the car to carry more speed through technical sections.

Beyond performance, its distinct layout and brushed-steel finish give the car a unique and aggressive look — a true statement piece on the track.

The chassis is supplied with Torx T10 screws, provided in a quantity greater than required to include spare replacements.
In the comparison table below, you’ll find a reference between the original Schumacher screw lengths and those recommended for use with the Boost RC spring steel chassis.
