First gen Impreza and Forester for sure

Second gen, I think is also compatible, I'm just not entirely sure if there were any changes to the caliper mounting points.

$20 is pretty cheap and probably worth the gamble. Just keep in mind that there is a high likelihood that you will be fighting the removal of the lateral link bolt and might also have to fight the axle removal.

I've had to remove entire lateral links because of bolts seized in bushings. And I also had to replace an axle before because I couldn't get it out of an old knuckle, bent my 12 ton hydraulic press trying to get it out!

So, I recommend putting a hand sledge in with your tools when you go to pull them, just in case you're having to beat on some stuff.
