Kwan is right because teh 2.5i has equal length headers.

 

but we aren't talking about a 2.5i...we are talking about a 2.5rs which has UEL headers...when i wrote saying the sway wont work in my head i was thinking we were talking about a 2.5i, now i notice we are not...so the front sway should work

 

Do both for sure. dont just crank down the rear and think that because back end is now coming out that you fixed the problem though.A lot of people make the mistake of making the rear bar to stiff and insted of corecting understeer they cause oversteer witch will actualy slow you down also. I would recamend buying swaybars form a company that dose testin as we do. (cobb, whiteline, Kakumei, tein) sorry ours (Kakumei) is not out, quite yet. they will be in the US soon .

good luck with your car and take things slow.

thanks for the help guys

 

Front sway bar will not fit, rear anything that can be done for the wrx will fit. Endlinks, swaybar, rear mounts..etc.
