so to get down to the real question, would a diameter difference of 25mm (sti being 25mm bigger than calipers came stock with) be a drastic and debilitating upgrade.

caliper rated for 297 rotors and rotors being 326. doable or no.

what are you planning? i bigger rotor has may advantages, more torque, more heat soak and greater surface area. Are you looking for a brake upgrade? if you don't want to "brake" the bank with a full Brembo set up you can get the 2005 legacy Gt brake caliper and rotors for pretty cheap. They are a 2 piece floating caliper like stock brakes but have a 316 mm front and a 290 mm vented rear.

Then you could use whatever diameter rotor you want.

ok but what about the contact patch of the brake pads to the rotor. that has to be affected somewhat.

as the rotor gets bigger and bigger you get less and less contact with the brake pad to the face of the rotor. even if you did do it right.

i think im going to go with the legacy GT ones. they are pretty close.

You don't lose contact patch if the brackets you make set the caliber in the same spot as the oem ones.
