SVX/Legacy brake interchange

[Jvan]

This isn't about a swap but more about what Legacy brake parts were used on the SVX. The SVX uses Legacy 1 pot rear calipers; I want to know from what year(s) and trim level(s) Legacy's(N/A/AWD/Turbo)? I found a company that sells rear big brake kit upgrades most for Impreza/WRX/Outback/Forester models w/5x100 bolt spacing to upgrade rear rotors to 290x10mm the same size as ours except for the 5x114.3 spacing. Where it becomes relevant the SVX, is that the kits also include an upgrade to STI rotors using our 5x114.3 spacing; the rotors can increase to 316x 18mm w/5x114.3 spacing and use Legacy 1 pot calipers. Sound familiar. The Legacy 1 pot calipers are from 90's and are Legacy Sport calipers. So do we have Legacy Sport calipers and only need to upgrade to STI rotors. Once I find out what calipers the SVX uses, I will contact them to inquire. Maybe we don't need to buy anything other than brackets from them and can source STI rotors/pads/Legacy calipers from aftermarket Subaru sources. Before someone responds that there are Brembo kits available, I don't need them for every day driving and they are expensive (worth the cost for certain applications).
