Here is a dumb question and I may have overlooked the answer. in this post:
Swaybars and Swaybar mounts/bushings
All rear swaybars for any 02-07 RS and WRX will fit. STi rear swaybars will mount on the outside of the endlinks and their effectiveness is reduced.
04+ RS, WRX, and STi rear swaybar bushings will not fit 02-03 swaybar mounts.
04+ RS, WRX, and STi rear swaybar mounts will fit and are an upgrade but require 04+ swaybar bushings.
Front swaybars for 02-07 WRX will fit, except on RS models.
02-07 Impreza RS require a specific sway bar to clear the non-turbo headers. WRX and STi front swaybars will not fit an RS.
Am I to assume the front sway bars are interchangeable between 02-07 WRX's and STi's?
edit - I am doing the Wagon to sedan front end conversion and have all teh parts. I just need to know if I ordered the wrong sway bar. thanks.
