blatantly stolen from NASIOC
FYI
1. 04+ means 04 and up
2. suspensions between 02+ and the 04 STi are interchangeable. for example, you can run KYBs with 03 springs and 03 tophats on your 05 WRX.
3. any strut made for an 02-03 WRX can be used with 04+ WRX springs and 04+ WRX tophats, but you will need strut spacers from TiC.

7. 04+ springs require 04+ tophats
Struts
Strut: KYB AGX
Springs: All springs will fit. However, 02-03 springs must use 02-03 top hats. 04+ springs must use 04 and up top hats AND a washer from TiC.
Models: This strut assembled properly with springs and tophats will fit, 02+ WRX, and 04 STi. This strut assembled properly will not fit 05+ STis due to the front knuckle redesign. My understanding is that the rears will fit 05+ up STis.
Strut: Tokico D-Spec
This strut fits the same as the KYB AGX.
Strut: Koni Insert
Notes: Koni only makes inserts for use, so in order to use them you will need struts from an 02+ WRX. STi struts will not work because they are inverted. You take the 02+ WRX struts and hack them up. *insert link here for directions)
Springs: All springs will fit. However, 02-03 springs must use 02-03 specific Konis and 02-03 tophats. 04+ springs must use 04+ Konis and 04+ tophats.
Models: This strut assembled properly with springs and tophats will fit, 02+ WRX, and 04 STi. This strut assembled properly will not fit 05+ STis due to the front knuckle redesign. My understanding is that the rears will fit 05+ up STis.
Strut: Ohlin Fixed Perch 04+ WRX and 04 STi
Notes: These babies cost $$$!
Springs: Only 04+ springs will fit because 04+ tophats must be used.
Models: This strut assembled properly with springs and tophats will fit, 02+ WRX, and 04 STi. This strut assembled properly will not fit 05+ STis due to the front knuckle redesign. My understanding is that the rears will fit 05+ up STis.
Strut: Ohlin Fixed Perch 05+ STi
Notes: These are pricey and rare. If you want them contact
http://racecompengineering.com/ or
http://www.gtworx.com. Arguably the best fixed struts for the Impreza.
Springs: Only 04+ springs will fit because 04+ tophats must be used.
Models: This strut assembled properly with springs and tophats will fit 05+ STis. This strut assembled properly will not fit 02+ WRX, and 04 STi due to the front knuckle design.
Suspension TakeOffs
V7 is equivalent to the 02-03 WRX model years in the US.
V8 is equivalent to the 04-05 WRX, and 04 STi model years in the US.
V9 is equivalent to the 05+ STi model years in the US.
When talking about full takeoff suspensions, V7 and V8 are interchangeable. So, a V8 suspension will fit on your 2002 WRX just like a V7 suspension will fit on your 2005 WRX.
If you want to fit a 2005+ STi (V9) suspension on your WRX...
