Takashima D-13 CAT PB Concept Spring Steel Chassis

Following extensive track testing and continuous refinement, Takashima D-13 has released its new 1.2mm Concept Spring Steel Chassis for the Schumacher CAT PB 1:10 4WD Buggy.  Developed specifically for modern high-grip racing conditions, compared to a conventional aluminium chassis of the same design, the spring steel version features a significantly thinner profile while maintaining exceptional strength, resulting in a lower centre of gravity and improved overall chassis balance.  Thanks to the unique material properties of spring steel, the chassis also delivers a more controlled flex characteristic, allowing the suspension to work more efficiently under load.  Unlike aluminium, spring steel has a much higher elastic modulus, enabling the chassis to return to its original shape more consistently after repeated loading.  This provides more repeatable handling, improved chassis consistency and a more predictable driving feel throughout a race.  On the track, the 1.2mm spring steel chassis offers increased cornering stability, improved rear traction and more precise steering response, while maintaining excellent support through high-speed sections.  These characteristics make it particularly well suited to high-grip carpet and clay tracks, where excessive chassis flex can reduce consistency and overall performance.  Designed to combine a low centre of gravity with an ideal balance of rigidity and controlled flex, the Takashima D-13 Concept Spring Steel Chassis provides Schumacher CAT PB racers with a stable, confidence-inspiring platform capable of delivering consistent lap times under demanding race conditions.
