Show original supplier description
The IE Rear Sway Bar Upgrade is engineered to provide precision control and agility for your Audi C8 RS6 and RS7. This suspension component sharpens handling and improves body control by reducing body roll and countering understeer, allowing for faster cornering and increased grip. It features user-adjustable stiffness settings: the rear mounting position offers a 190% increase in stiffness, while the front mounting hole provides a more aggressive 280% increase. The integrated polyurethane bushings eliminate the "sloppy" feel associated with stock rubber bushings, significantly reducing flex between the sway bar and chassis for a tighter suspension feel without introducing noise. Installation is a direct, simple bolt-in process, with an average install time of around 1 hour. No special tools are required. For optimal handling, it is recommended to install iE Sway Bar End Links simultaneously. Compatibility is confirmed for Audi C8 RS6 and RS7 models from 2021-2024.
