2011 STI Hatch


I plan to keep this second post updated with some recent work:

This past weekend I pulled the front axles due to a vibration when accelerating at high speed. A local shop rebuilt the axles (passenger side was bad) and I am going to put them in this weekend. Fingers crossed the vibration is gone. Side note: if you are pulling the axles and it is stuck in the hub, rent a tool to push it out from autozone.

Last month I re-did my suspension setup adding multiple bushings, cygnus coils, and roll center adjustment. Lot's of hours, two injured helpers, and tons of grease later.. It feels fantastic on the road.

Carbon driveshaft was a quick, easy mod that brings joy to every drive.
