BUILD LOG:
WRX-maniac's 2012 STi Limited Sedan




















The Story:
I traded in my 2011 WRX for this STi in June of 2016. It has been my dream to own an STI since I could drive. With finally owning one, my goals are to eventually end up making this car my weekend warrior/track car. Although I will have to DD it for a few years. My main focus will be making good horsepower, while building up the suspension and drivetrain components at the same time. Overall I just want this car to be everything I have always envisioned it to me in my mind, and have fun while doing it. Hope you enjoy!

Thanks man. And you know, my last two wrx's were hatch's, and I loved them. But I always told myself that if I got an STi, I was getting a sedan. Don't know why...... I guess the look of the big wing? lol. I don't know.

Debating ordering the window chrome delete vinyl from Premium Auto Styling....... Can't decide between gloss black, or matte black..... leaning towards matte black. What do you guys think?

Im debating what route I want to take with my STi, looks wise. My last three Subaru's have been WRB, in which I have put gold wheels on. Although I love the gold wheels on a WRB car, im thinking about blacking out my car. Tinting the windows, blacking out the window trim, black side garnishes, and maybe even black wheels one day. Not gonna lie though, for the first time ever I am considering keeping the stock wheels as my summer wheels and buying cheap winter beater wheels. I actually really like the look of the BBS's that come on my car.

Thoughts?

Ordered my window chrome deletes today from JDMFanaticVinyls in gloss black. Next week I will be making an appointment to get my windows tinted (20% all the way around) and hopefully ordering my black side garnishes and shorty antenna.

Thanks man! It's getting there. Made an appointment to get my windows tinted next Tuesday. Going 20% all the way around, plus the front windshield strip. Other than that I still have to do the window trim chrome delete and put the black sti side ornaments on. Once all that is done im doing a full detail with all the supplies I bought that are pictured in this thread and going out with a buddy to do a photo shoot.

A professional photo shoot of your whip is going to look mint. Any idea on the scenery or setting you will have it pose in? Cannot wait to see those photos!
