If you're in the Mid West area I highly suggest attending this event. Though a Subaru specific event, it's friendly for all car enthusiast and we highly encourage you to invite your friends/family.
86 twins(yes, BRZ AND FR-S) will be allowed to register/participate for both the car show and auto cross event. Car show category specific to the twins is pending and dependent on whether or not there is a large 86 showing. Last year there was only 3-4 of us, so we definitely need to change this!
