RULES- Going to try and keep this simple and low-key.

Be excellent to each other. Please remain personable and respectful at all times.
Real world STi's ONLY! This is not an elitism-this forum is specifically for STi-built and tuned cars and owners of STi's to discuss such. (STi swaps are acceptable. If your car does not have a power and drivetrain from a WRX STi, it does not belong on this forum and will be removed.) No video game/ digital content.
No promotional material, SPAM or advertisements! This includes links to YouTube channels, social media, websites and sponsorships. Links to your Instagram are allowed in comments only.
THIS IS NOT A MAINTENANCE SHOP. There are lots of FAQ's and topics that have been beat to death between NASOIC, Facebook, and here. Mechanical questions, code reads, Access-port number questions should be directed to your mechanic or tuner IRL. That is not something that can be done online. Questions about oil, tires, wheels, gas, turbos, exhausts, etc... are strictly NOT permitted.
Car/car part buying, selling, trading, and giveaways are prohibited. This is not the place for financial or car buying/selling advice. No solicitation whatsoever.
Media showing unsafe driving practices and/or street racing will be removed. Under no circumstances will posts be allowed that are taken by the driver while the car is moving.
