IN support of the preseason cycle for the ATCC, some of the future events in the American Racing Club will be using Race On content. While this is not a permanent switch, you will see some of the Friday Night WTCC events will be using this game platform. My plan is to alternate weeks so your under no huge pressure to get the game tomorrow...............but you should get it soon. It is not very expensive to buy as an add-on to Race 07 / GTRE etc. and can be done directly from STEAM for convenience at $24.99 USD or you can take the Bundle at $29.99 and includes STCC the game. NOt 100% sure that STCC will be a part of the ATCC, but for an extra $5 just take it as insurance. Thanks for your understanding and look forward to seeing you on track soon!
