A well-known issue in Underground 2 is a glitch involving "missing" Street X races in Stages 3 and 5. If these races are not completed, your save file may get stuck at 98% or 99%. The community-verified method to bypass this is to select sponsors that "force" these races into your contract.

Note: These codes primarily unlock the visual vinyls for the sponsors rather than the monetary contracts, but they are verified unlocks within the game files.

Avoid contracts with too many Circuit or Sprint races if you struggle with AI "rubberbanding" (where opponents unnaturally catch up). Instead, look for contracts heavy on Drift or Drag if those are your strengths.

Sponsors become available as you complete races, URL events, and increase your Star Rating . Each sponsor gives you a discount on specific part brands and a visual customization bonus (neon, vinyls, etc.).

You must clear a set number of mandatory events highlighted on your map.
