The various upgrades only become available after you've completed
so many races. After race 6, you get 3 level 1 performance upgrades,
after race 7 you get one TJ unique upgrade. After race 9, you
get 3 more level 1 peformance parts, and after 14, you get the last
3 level 1 parts. This continues on through the underground mode,
you get the last standard level 3 performance parts in after 92,
and the last TJ unique after race 97.
