Moton developed a custom set of double-adjustable remote-reservoir motorsports dampers.
Custom wiring harness was built to interface with the MoTeC ECU.
The Scion's DBW throttle module was a major problem, so GST converted the tC to a mechanical throttle body and cable setup from a Subaru WRX.

Focused on developing the handling during testing, fine-tuning and refining damper and sway bar settings.
Mike from GST Motorsports refined the ECU mapping and turned the boost up slightly. Peak power was 280 whp and 270 wtq (up by 30 whp and 30 wtq from 2007).

Increased grip via improved downforce, wider front tires and rear suspension changes.
Indy Car front winglets from a '00 Reynard Indy Car were mounted on the Scion's hood, directly above the tires for best transfer of downforce (an idea carried over from the MPME '05 Subaru that also used these winglets).
Installed a new rear wing from wingshop.co.uk with a profile designed to work well at the cornering speeds the Scion would be achieving around Thunderhill.
Moved up from 235/40R17 front tires to 255s to achieve more mechanical front grip.
Adjusted the handling balance to match the improved aero and front tire grip.
A bigger rear antisway bar made by Hotchkis and softer rear springs and shock dampening.
