Spec II is a mod which expands upon the core Gran Turismo 4 experience, bringing a variety of fixes and improvements to the game. As the name may suggest, Spec II primarily aims to improve on the game in ways that I feel Polyphony Digital themselves would, while also adding a few modernised features and challenge run-friendly options.
Spec II is based on the NTSC version of Gran Turismo 4 Online Public Beta and is distributed as an xDelta patch requiring this version.
