05 sti fender flares $600 shipped
  • Made from FRP material
  • never installed
  • Professional installation recommended

these are great for guys looking to run wider 9-10 inch wide wheels.
These flares are made to fit the 05 sti but can work with 04 sti as well but will have a small gap for the rear flares since the 05 has an extra trim that goes around the rear wheel well.

HKS style rear diffuser $430 shipped
This diffuser is carbon fiber but does have clear coat chipping/fading.
However that can be fixed from a body shop or just paint/plasti-dip it black and it will be just like new
