The best way to improve handling and response to an E46 is to start at the control arm. The OE bushings are designed more for road comfort than performance, meaning they're soft from the factory and cause all kinds of deflection. When you upgrade to a more stiff polyurethane bushing the control arm has a more direct connection to the vehicle taking the slop out of your handling increasing your precision. The Turner 80a bushings are mush stiffer than stock making this a perfect balance for an upgraded street car, providing enough comfort for the street with similar control you'd find in a solid mount.
