Hello. i searched very hard and had no luck.

I have a 2002 subaru wrx and just bought a set of 2007 sti sway bars. Both front and rear. My question is ... what is the size / diffrences in the 2 sets. thank you very much!

 

wait a sec... this question is phrased a little funny...

so lemme get this straight - you spent money on something when you didn't quite know what you were getting????

2002 WRX Front
All Models: 20mm

2002 WRX Rear
Sedan Turbo: 20mm
Sedan Non-Turbo: 13mm

Wagon Turbo: 17mm
Wagon Non-Turbo (Including Outback): 13mm

2007 STi USDM sway bar size is 19mm front and rear.

Rears are different and fronts, maybe.

Whiteline's website shows that the 2003 and 2007 STI front bar is the same as the 2003-2007 WRX Sedan.

The 2004, 2005 and 2006 STI front swaybars are different than the WRX of any year.

The 2001-2002 STI & WRX front swaybars are the same.

Nice, eh?

Wagons are different all together.

 

Yeah, I think they are different lengths also, right? I remember people talking about putting the end links on the outside vs. inside for the different years and trims just to get them to fit.
