If your racing heart is in the mood for some more Forza Horizon, then hold tight because the Rally Expansion Pack drops in the Xbox Live Marketplace tomorrow.

For the cool price of 1,600 Microsoft Points (or $20.00), you can get your hands on all of the new rally content, which includes five new cars to drive around Colorado's off-road stages. Or, if you've purchased the Forza Horizon Season Pass, you'll get the content for free!

The five cars you'll receive are the 2005 Subaru Impreza WRX Sti, the 1982 Lancia 037 Stradale, the 1992 Ford Escort RS Cosworth, the 1992 Toyota Celica GT-Four RC ST185, and the 2004 Mitsubishi Lancer Evolution VIII MR. If that wasn't enough to rev up your excitement, Season Pass owners will also get the 2003 Ford SVT Focus as a bonus!

You can take all of these beauts out for a spin in the new multiplayer rally racing events, rival challenges, and career events complete with leaderboards. According to the Microsoft press release, the stages will feature "sudden elevation changes, massive jumps, and more surface variety than has ever been seen in 'Forza Horizon,' providing an intense and varied off-road driving experience."

Check out the trailer below and let us know if you're ready to kick up some dirt.
