Horizontal Motorsports All-Subaru Autocross
The Horizontal Motorsports All-Subaru Autocross is an opportunity for you to test and dial in your skills as you try for your best time around our Subaru-in-mind designed course! Autocross events are safe, medium speed driving events for you to test the limits of your Subaru and gain valuable driving experience! One driver at a time negotiates a course laid out with the cones, or pylons, testing their skill against the clock. Time penalties are charged for disturbing cones.
Newbies are encouraged! Instructors available upon request!

You'll need to sign up in advance and start by purchasing a ticket to the event. From there, you can add an autocross registration. You'll also need to be 18 or older with a valid driver’s license. Numbers will be assigned upon arrival and cars may be required to install a branded windsheild vinyl and/or number plates.
No Work Assignments!
Unlike most Autocross formats, we'll have staff so you don't have to work when you're not running. This way you can enjoy the event!
Preparing Your Car / Tech Inspection
Remove all loose articles from the interior of your car! At the “tech” area, you will be asked to open the hood, trunk, and interior of your car for the Tech official’s inspection. They are here to make sure that all cars competing are safe. They will inspect your tires for adequate inflation pressure and tread depth, your wheel bearings for wear, check that your battery is secure, throttle return springs for return, etc. If the tech officials are satisfied with the safety of your car, your time card will be initialed. NO FLUID LEAKS! No loose seats. No frayed seat belts! Helmets are required, must be SA2010, M2010, SA2015, or M2015, and are subject to inspection. No passengers allowed.
To pre-reg, start by purchasing a ticket here. After you've selected your admissions ticket you can add an autocross registration to it.
