Does anyone know if a wrx or sti rear OEM 20mm swaybar will work on a gc? Your help is greatly appreciated.
the sti's are wider IIRC. so they wont fit. they will fit on wrx's but you'd have to put them on the outside of the endlinks and this kind of screws with the effectiveness/geometry of the setup.
They will both work on your car. The wrx swaybar will fit perfect, but the sti bar is a bit wider so you will have to put the endlinks on the inside, I've used both on my rs. IIRC the stock wrx rsb is 17mm and the stock sti rsb is 20mm, they stock rs rsb is 13mm so either bar is an improvement.
