I didn't see this posted so yeah...
The yearly Subaru only autox event at SIA (Lafayette, IN) is coming up. It pulls in plenty of great competition and community. It's confirmed that some of Subaru's pro drivers will attend (and may drive). Dave Mirra with his global rallycross STi and David Higgins with his gymkhana STi. The event will be hosted by the Indianapolis region SCCA group and Subaru.
Even if you don't run it's a fun time and there will be a large cruise afterwards. Cruise in at O'reilly Auto Parts in Lafayette, the goal is to bring a large Subaru/autox group to convince other folks to join the clubs and come to events.
I know this sucks but Scions can't race, it's a Subaru make only (they never allowed Saabarus either). You can still attend though!
