1. Hydraulic handbrake: This is used for staging the car and preloading the drivetrain before launching.
2. Ikeya sequential shifter: This unit converts the normal H pattern shifter mechanism to a sequential action. Pull back to change up a gear and push forward to change down. These really are only suitable for dog engagement gearboxes where the clutch isn't needed.
3. Air shifter ram: This ram is actuated by the Motec ECU and uses high pressure air to move the shifter and perform the gear change.
4. Control panel: This panel contains the master ignition switches and the starter button, as well as the comms port for the ECU and SDL dash. The yellow and green buttons control the SDL dash display.
