Since the part numbers are the same for '01 thru '03+ I still don't believe they changed anything in the rear axle for a built in bar. I owned an '01 with the factory rear sway and a '03 GT and '04 PT and stock for stock the '01 handled much better with the rear sway than either the '03 or '04 without rear sway. I'd still go with a bigger front sway when adding a rear, though, as Dream4 stated.
With all of the choices for lowering springs I'd never go ghetto and cut springs. Leave that for the ricers as they bounce down the road with cut springs on their stickered Hondas.
