U9573 Schumacher Steel Chassis Kit - LD3

The Schumacher Steel Chassis Kit - LD3, part number SCH-U9573, is a steel chassis conversion suggested for the Cougar LD3 racing buggy. It is designed to create a lower centre of gravity while adding controlled chassis flex, helping the car remain composed across a range of track surfaces. The conversion is particularly suited to medium-grip, bumpy Astro through to high-bite Astro and carpet conditions, based on Schumacher team testing. This makes it a useful chassis tuning option for drivers looking to adjust the handling characteristics of their LD3 for changing grip levels and track conditions.

Chassis Tuning Features

The main chassis is made from 1.2mm steel and works with carbon fibre side pod stiffeners and front alloy 3D-printed stiffeners. Together, these components increase steering response while retaining the ability to fine-tune the feel of the car. The front stiffeners can be removed when a different handling balance is required, providing an additional adjustment option without changing the core chassis conversion. The result is a flexible setup choice for Astro and carpet racing where surface grip and bump levels can vary.

• 1.2mm steel chassis
• Carbon fibre side pod stiffeners
• Front alloy 3D-printed stiffeners
• Removable stiffeners for additional tuning adjustment

Suggested compatibility is with the Schumacher Cougar LD3. The kit is intended for racers who want to explore the benefits of a lower centre of gravity and increased chassis flex, while retaining the ability to adapt steering response and handling to the circuit. Its tested performance focus covers bumpy Astro with medium to high grip and carpet tracks.
