yeah but for a Gen1 3SGE my thoughts would be go the 165/185 brakes.
A 20 minute bolt-on job that's so easy that it's... uh.. really easy!
edit: however for searches and posterity, I am pretty clueless as to what 4-piston brakes go on a 162 well. I know RX-7 calipers are a popular upgrade also. You need a custom mounting plate made up for them though, and of course new rotors.
