Dont waste your money on the SVT front sway bar, its the same size you have already. The only models that came with a smaller front sway bar is the SPI LX sedan, and the 05 S sedans. Never did the ZX3 come with a smaller front sway.
What I would invest in is some new endlinks for the sway bars. Pick up some MOOG OEM replacements for the front sway bar, and some poly bushings for the rear. The MOOG will look stock but are beffier and have zerks on them.
