For those that track their A4S4 often or want a much more aggressive feel when attacking a canyon road Hotchkis Sport Suspension offers the Extreme Front Sport Sway Bar Set. This set uses a 35mm tubular front bar that is 60 stiffer than stock. Included are replacement polyurethane bushings front and rear bushing brackets front and rear along with 90 - degree grease fittings front and rear.
