I'm looking to upgrade my 2009 WRX Sedan to Stage 2...from stock.
I don't understand how to do this... I was looking at the Cobb Tuning kits, which run at around $2,000...and they are for 08+ STi's, or 2011+ WRX Hatchback.
My question is: How can I upgrade my 2009 WRX Sedan?
Why is there a difference between the Hatchback and the Sedan? The frame almost looks the same...and the engines are the same.
How much will it cost?
