I think you just use your stock ones but I could be wrong. Read through the suspension stickies in the suspension section. All the info is there.

Yea you dont use your stock ones, you need the impreza perches front and rear. Ive read through and I know that much, I was jus lookin for specifics and couldn't find any.

With a 91 you'll need the rear strut tops as well.
Front upper spring seat: 20323FA000
Rubber spring isolator: 20325FA000
Rear strut top mount: 20370FA200
Rear upper spring seat: 20373AA200
Rear rubber spring isolator: 20375AA030
(part numbers may be out of date but they work if you plug them into subarugenuineparts.com)
And then if you wanted to upgrade the front top mounts I'd go with the whitelines.

They only make them for the front, and they are offset to get you more camber and caster. On an older car they result in mostly extra caster:
Rallispec lists having group n rear strut tops, and SGP has these which are stiffer but not quite the same:

What about whiteline fronts and group n rears?

Yes, that's what I was suggesting, although I guess not very clearly. I have heard that the group n rear mounts for the GC are discontinued, and subarugenuineparts only has those "P1" rear mounts, whatever hardness that is. Those and group n are pretty much the same price as the stock tops anyway.
You could go cheaper by getting starndard rear tops from rockauto or whatever and then using the stock fronts, but having a stiffer mount, especially up front, is a really good thing for performance and handling.
Also if you need somewhere to get the whiteline tops let be know.

I was going to suggest getting them from me (and yes they would be cheaper than whiteline's msrp). However I just checked on availability and they are backordered for at least another month. So whiteline doesn't have any in the US and neither do three of the bigger parts distributors so I would double check before ordering a set off some website.
