-Nameless performance catback exhaust
-COBB stage two OTS tune
-Aero dynamic front splitter with support rods
-Turbo XS Hybrid 50/50 blow off valve

Wheels and tires:

Kindly help me class my car correctly? Thanks everyone!!

Your tune automatically bumps you out of the WRX's stock class (DS) and the splitter moves you out of its street touring class (STX) so your best bet is to run our California Street Tire (CST) class as the rule set really only requires the car to be on street tires. Also be sure to sign up for the Novice class so you can compare yourself to other new drivers (we will average everyone's time based on their class)!

Look forward to seeing you out there and feel free to ask anyone for help.
