Are you talking about WRX 4 pot brakes? I'd say you are, you'd be looking and trying to bid against others that are wanting this easy upgrade too!
My old 92 Gen1 Series2 GX with a RS conversion Wagon I fitted SB Forester brakes to it, they are only 2 pot brakes but have the same rotor disc diamater @ 294mm (stock RS 277mm GX = 260mm) they also have the same braking force/clamping pressure.
These outbraked alot of other Qld RS cars on every cruise I went on as well as many mountain runs never developing any fade. These are alot cheaper than going with 4pots too, I got mine from Sunspares in Yandina, QLD as a package which was Rotors/Calipers/Pads for half the price for the same condition 4 Pots, unless your doing track work the 4 pots add no extra value. If you want them painted, clean them and spray paint them with UHT brake paint to what ever color you desire.
For more tuning/modifying tips for the Gen 1's you should sign up to RSLC (
