And: If Tires/Drivetrain give more speed than Suspension/Exhaust, I'd always prefer to upgrade in the order Drivetrain (also contains acceleration), then Tires (with handling), and only then Exhaust and Suspension.

Usually I even wait for more engines, even if I could upgrade Exhaust or Suspension because lower levels need less engines.
