RDKLSTi | 9:1 | Outfront Longblock | DeliciousTuning FlexFuel (E85) | GTX3576R

It became a bit of a nightmare to maintain a build thread on five different forums, each having their own ‘per post’ image limitation. I decided it was time to migrate everything over to a stick on my site to simplify things.

This post will list the modifications and a bit of the story behind my 2008 STi. I will update this as time permits with timelines and other information regarding the path that led me to having a nearly non-daily-driveable daily-driver. #becausedailydrivenracecar
