Yes the calipers are different. No brackets are required.Another resurrection...
At 60,000 I'm getting a vibration in the brakes, so I want to go straight to LGT brakes.
Are the calipers really different, or is it just the rotors and brackets that need to be changed?
I only ask because when I upgrade my Impreza to WRX-spec brakes, I only needed rotors and brackets (the calipers were exactly the same).
It's very easy. Just go on Rock Auto and order Legacy GT Calipers front and rear and of course get rotors and pads. Everything will just bolt right up. Then you can send back your old calipers for a core refund, so it ends up the calipers are only like $50 each.
All the parts cost is like around $500 (after core refund)
