Yes, the 2002-2005 wrx springs are shorter and I think the valves are different length as well.

The springs in the 96-98 dohc 2.5 and the ej20k are longer than the 02-05 wrx springs. I got a set of shims by ferrea that allowed the shorter ej205 size springs to work in my ej20k heads but ferrea doesn't have them anymore. The ones they sent me sucked anyway and I had to send them back because their sizes weren't accurate. Finally they returned in the correct size and I installed the dual supertech springs. The ej25d n/a heads have the same spring and valve setup as the ej20k, just different spring pressure and some had sodium filled valves.

From what I remember, the shims ferrea made were 6.40mm thick, which made the ej205 spec supertech dual springs fit correctly. They replaced the oem spring seats. I also had supertech valves for the n/a ej25d in my ej20k heads.

If you contact user 2pot, he may be able to share the specs of some shims he had made for his setup. I think a machine shop made his, they looked to be of better quality than the ferrea.

93-01 Impreza (GC and GM) axles are same length in front. You just need to confirm if your old axle is male or female on the inner end and if you need an axle with the abs ring on the outer. I've bought aftermarket axles and they came with pressed on abs rings, which I tapped off with a mallet and punch because my knuckles had no room for the ring. The 02-07 Impreza(GD) wagon axles are also the correct splines inner and outer and have the correct length.

Thank you kindly!!! When you say male and female I guess the male has rod going into the transmission? So my car will either have either male or female, not mix of both? For the GD wagon axles, it has splines inner and outer, I would get that if mine are male?

Yes. Also pay attention to whether your car has abs. If not, you will need to remove the abs rings from the axles.
