racecar parts make racecar noises, there's a reason OEM has a bunch of non-metallic poly bushing material. I switched to SPC/Whiteline steel rear control arms, they squish down on the endlinks and damper to minimize noise (unlike the shiny aluminum ones) and I switched back to the OEM swaybar endlink exactly for this reason (I also bent my racerx endlinks hitting a pot hole), I also have OE rear top hats. Goodluck.
