Hotchkis 04-08 Audi RS4 Front & Rear Sport Swaybar

If you're looking to sharpen the handling of your 2004-2008 Audi S4 or 2007-2008 RS4, this front and rear sport sway bar set from Hotchkis is a solid choice. These bars are designed to significantly reduce body roll, giving you a more connected feel to the road, especially when you're pushing the car through corners. They're built with track and autocross use in mind, offering a distinct advantage over the stock setup for spirited driving.

The front sway bar is a beefy 35mm (1-3/8 inch) tubular steel bar that's about 60% stiffer than what came from the factory. In the rear, you get a 29mm (1-1/8 inch) tubular steel bar that's not only stiffer but also adjustable. You can tune the rear bar's stiffness across a range of +235% to +305% over the stock RS4 bar, allowing you to fine-tune the car's balance for different driving conditions or preferences. This adjustability helps you achieve a better slip angle, letting you apply power earlier when exiting corners. The bars are finished in a durable gloss black powder coat and come with greasable polyurethane bushings and brackets equipped with 90-degree zerk fittings for easier lubrication.

This package is built for performance and durability, having undergone extensive track testing. While it's designed for track and performance street driving, the improved roll stiffness will be noticeable even in spirited daily driving. You'll want to refer to the manufacturer's installation instructions for the specific procedure, but the included greasable bushings make maintenance straightforward.
