that's pretty much it. also - is the STi rear sway bar 20mm or 22mm?

 

No.

 

20

 

crap...so what WILL fit a 2002 wagon? 02-03 sedans only?

 

You cannot fit an STI sway bar because the ends of the bars are centered on the endlinks, rather than being on the inside or outside (screwing up the geometry). I know because I wasted time trying it for myself.

The 2002 wagon can use any sway bar for a 2002-2003 WRX sedan/wagon. The 2004 WRX (non-sti) bar will fit, but the bushing won't.

Enjoy-

 

thanks a bunch....guess that $40 STi sway bar I've been eyeing on Ebay was not meant to be

 

the 02/03 rear bar will fit (20451FE000) as well as the older 20mm GC STi bar (20450FA040)

If you want to use 04 bushings, you need the 04 sway mounts
