Life Racing SD4 Racing Wheel | Professional Steering Wheel Display & Interface

The Life Racing SD4 Racing Wheel is a flagship control hub designed for elite motorsport. By integrating a high-resolution 4.3” display directly into the steering wheel, the SD4 provides drivers with critical information exactly where they need it. With 18 tactile driver inputs and dual-processor power, it serves as the ultimate command center for managing engine strategies, traction control, and chassis settings in real-time.

Elite Visual Clarity & Intelligence

• 4.3” High-Resolution Display: The WVGA ultra-bright screen is engineered for maximum legibility in high-glare open-cockpit environments.

• Intelligent Auto-Dimming: Features an onboard light sensor that automatically adjusts brightness from midday sun to midnight endurance stints, ensuring optimal contrast without driver glare.

• Instantaneous Processing: A powerful RISC CPU handles complex display logic and advanced strategy execution with zero lag.

Comprehensive Tactile Controls

Designed for mid-race adjustments, the SD4 features a robust array of inputs:

• 5 Rotary Switch Inputs: 10-position rotary switches ideal for managing traction control levels, engine maps, or brake bias.

• 10 Snap Action Buttons: High-tactile feedback buttons designed for mission-critical functions like pit speed limiters, radio, and drink systems.

• Customizable Inputs/Outputs: 3 general user-configurable switch inputs and 3 lowside outputs for expanded peripheral control.

High-Speed Networking & Integration

• Dual Ethernet Ports: 2 full-duplex Ethernet interfaces for lightning-fast configuration, firmware updates, and data management.

• Dual CAN 2.0B: Seamlessly communicate with any Life Racing ECU or PDU, as well as third-party data loggers and controllers.

• Synchronized Strategy: Execute complex math channels and vehicle strategies directly from the wheel interface.

Motorsport-Grade Construction

Built to handle the high vibration and thermal stress of professional racing:

• Ruggedized Design: Engineered for seamless integration into custom steering wheel plates and carbon fiber housings.

• Thermal Management: Optimized for reliable operation in extreme temperatures, ensuring performance never fades during a race.

• Compact Integration: The high-resolution display and switchgear are packaged to minimize depth, allowing for comfortable ergonomics and paddle shifter clearance.
