Help me clarify this a little bit, if you would please.
The 266x10mm(170mm) solid rear rotor is what is found on the MY02+ WRX, the BF Legacy, and atleast the MY99+ RS, correct? It also sounds like the WRX, RS, and BF Legacy share the same caliper too, is that correct? So, for a rear disc upgrade for my L Wagon I can use the BF Legacy, WRX, or MY99+ rear rotors and calipers since they are the same? Now, if I want to further upgrade my rear brakes, I can choose the 290x10mm(170mm) solid rear rotor and caliper found on all 2000+ Legacys.
Are the bearing specifications and hub/axle specifications the same in that any of the rotors and hubs will go right over any of the other axles; utilizing the same bearings and everything?
Do you happen to know what the previous STi models used for the rear discs?
Perhaps, can we do something like this for the front brakes as well? The goal would be to find the possible front/rear brake upgrades that yield what Subaru determined as proper brake bias.
