The sweepstakes for our 2018 Subaru WRX STI has come to a close. This car has been a fun project for the throtl team. In today's episode of throtl, we show you the entire build process of the WRX STI from start to finish. When we first got the STI, it was a clean chassis with low miles. This made the build process a streamlined process because there was no major maintenance that needed to be done. This meant that we could get straight to installing after-market parts. Check out the video below to see how we turned a Stock Subaru WRX STI into a fully modified beast!
