I think the word "Race" is misleading considering the game seems to be intended to make production cars, otherwise we would see stuff like racing fuels and various other things associated with motorsports. For the brake pads the word "Sport" seems more appropriate, however the cam/VVL profiles have Sport already so I'm not sure what could go there.

Also, Cam Profile and VVL Profile has the bottom words mismatched, one says "Low" and the other says "Econ", I would think these would be the same thing?

This is a pretty minor detail/nitpick I guess, but it would help prevent any confusion newbies might have about the game.

Better yet. How about Hard and Soft pads?

Because brake pads are never described as hard or soft, like tires for instance. They're all hard. Performance pads just have a higher coefficient of friction and more temperature resistance than regular street pads. I agree with the OP, "sport" would be more appropriate.
