The AiM GT32 is a 320 mm motorsport steering wheel designed for race cars using AiM data acquisition and power distribution systems. Its CAN interface transmits button and rotary switch states directly to the AiM PDM08, PDM32, or any CAN-connected device — no additional switch panel or relay wiring required. All 8 CAN pushbuttons have individually configurable RGB backlight for status indication: green for active, red for fault, amber for mode selection.
Eight CAN pushbuttons handle any circuit or function assignable in Race Studio 3 or the connected ECU/PDM CAN setup: pit speed limiter, rain light, wiper, fan override, traction control mode, launch control, brake bias adjustment, and custom functions. Two additional free-contact pushbuttons bypass the CAN bus for direct relay wiring to safety-critical functions (fire suppression trigger, kill switch) that must remain independent of the CAN network. Three RGB rotary switches adjust continuously variable parameters — bias, roll bar, differential — with the selected position transmitted over CAN.
Optional magnetic carbon fibre paddle shifters attach to the GT32 without screws or tools. The 6-bolt 70 mm hub pattern fits OMP, Sparco, and BG-Racing quick-release boss adapters. The Deutsch Autosport 22-pin connector matches the AiM MXG and MXP auxiliary connector, simplifying harness routing in AiM-based systems.

Compatibility with AiM PDM
The GT32 is designed to work natively with the AiM PDM08 and AiM PDM32 via CAN. Button presses on the GT32 can directly toggle PDM outputs, change PDM modes, or trigger programmed logic sequences in Race Studio 3 — replacing the need for a separate switch panel. The free-contact buttons wire directly to PDM digital inputs or vehicle safety circuits.
FAQ
What quick-release hub does the GT32 use?
The GT32 uses a standard 6-bolt 70 mm hub pattern compatible with OMP, Sparco, and BG-Racing quick-release boss adapters. Check your chosen quick-release boss’s bolt pattern (should be 6× 70 mm PCD) before ordering. Contact us for compatibility confirmation on specific boss models.
Can the GT32 work with any ECU, or does it require an AiM PDM?
The GT32 connects to any device with a CAN bus input using the AiM protocol. This includes AiM PDM08, PDM32, MX dash loggers, and ECUs that support the AiM CAN steering wheel protocol. For ECUs using a custom CAN protocol, the button states can also be mapped via Race Studio 3 as custom CAN channels.
What is the difference between the 8 CAN buttons and the 2 free-contact buttons?
The 8 CAN buttons transmit their state over the CAN bus to the connected PDM or ECU. The 2 free-contact buttons are hardwired connections with no CAN involvement — they make or break a direct electrical circuit. Use the CAN buttons for all control functions managed by software; use the free-contact buttons for fire suppression systems, kill switches, and any circuit that must function even if the CAN bus fails.
Are the paddle shifters included?
No. The magnetic carbon fibre paddle shifters are an optional upgrade ordered separately. They attach without tools using magnetic retention. Contact us to confirm paddle shifter availability.
