classic impreza or even later forester SG can be used .
ICP likely be able supply them
Was a company in poland selling new on ebay so keep eye out for that .
price new is around low 300 to 400 pounds
I was going link one on ebay, maybe worth asking questions on details of corosion level, if prepared blast/wire wheel it and treat/paint it price would be decent saving over new .
Can be quite a struggle swap them out without good tools like air impact, air hammer and air blade saw and bushing cups and forcing screws, need new lateral link bolts/bushes at the least .
Nice build 👍
Where did you get your arches from ? I’m looking to do a wide stance set up on my SF, iv got a set from a GC8 and a set from a blob eye, my plan was to attach them using nutserts but the fronts don’t quite look right 🤔
