not as alarming as it sounds but 2 weeks into the installation, had a rattle rear driver side harsh and kind of knocking noise, turns out it was a loose bolt and the rear sway bar I-link had its metallic ball coming out of the plastic socket, so replaced it for now but dealer looking into getting a stronger and sturdier rear i-link as the sway bar is so beefy the current setup cannot take the pounding.

just wondering if this is why Hotchkis recommends installing both front and rear.

had a similar issue in my B5 S4 with a rear sway that was too stiff for the subframe's own good and resulted in a cracked subframe. If a car like the RS4 was designed to have beefier sways, it would've had it already. And for those who track their cars, the said i-link would take even more of a pounding with stiiffer sway bars. Perhaps such problems would not be such an issue if only driven on the street and not very aggressively.
