RACE Injection

Hi all,

I have all of the expansion packs for Race 07, but I don't own Race Injection. Am I missing any content? The Steam Store page seems to suggest I'm not, but it's a little murky. :unsure:
Race Injection is basically Race07 and compilation of few addon packs:
- STCC The Game 2
- Formula RaceRoom
- GT Power Expansion
- Retro Pack
- WTCC 2010 Pack

If you have them (you suggest you have all addons) you are fine ..
