#19250, "RE: 2000 GS calipers on a 1999 RS???" In response to In response to 3 Aug-01-03 06:05 PM by Squid
The V6 3G switched to a single piston design in 2001 instead of dual pistons.
EDIT: I take it back I'm not 100% sure the fronts stayed the same size, but the rears definetly did. As proof check out the AEM big brake kit part numbers:
Eclipse 1989-94 2WD FRONT: 29-565
Eclipse 1995-99 2WD FRONT: 29-560 REAR: 29-630 BIG CALIPERS: 29-861
Eclipse 1995-99 AWD FRONT: 29-561 REAR: 29-630 BIG CALIPERS: 29-861
Eclipse 2000-03 V6 FRONT: 29-563 REAR: 29-630 BIG CALIPERS: 29-863
