calipers themselves are 100% the same..
carrier brackets and rotors are what changes

How the middle of the brakeline attaches to the suspension also changes. Older style bolts on, newer has a clippy thing.brake lines are different. G20s in the US have 3 different style brake lines from my experience(excludes 99 p11s since ive never owned one) all p10s are similar but changed to a different style flare fitting for 93.5 and newer. p11 brake lines mount differently than all p10 lines.
