Locked Rims and Vinyls
After "100%" game completion and legitimate, in-game cheat codes, players have complained of certain rims and vinyls remaining locked and unavailable by any method.
These can be unlocked only by picking the "unique part upgrade" and unique visual upgrade bonus cards in boss races.
Problem is, unique part upgrade cards can give you any part upgrade, not necessarily the one you wanted. To make things harder, there are only three boss races in the game that allow you to pick bonus cards. It boils down to this chart:
[1st boss][2nd boss][3rd boss][4th boss]
[Vinyl][Bushido ][21st Str][TFK ][Pharrell]
[ Rim][Multi C4][Torq-Thr][ADR Empr][HRE 943r]
[ Car][RX-7 ][Charger ][DB9 ][ ]
After beating the 4th boss, Darius, there is no bonus card screen. The most likely course; to obtain the nonexistent 4th boss vinyl/rim bonus cards, one must first obtain all three vinyls and/or rims from their respective boss races.
