To get the utmost control from your Mitsubishi Lancer Evolution 8 & 9, you need to upgrade any factory bushing you can. Whiteline has made it easy by offering kits for all of the control arm bushings. The Whiteline urethane control arm bushings are stiffer than the soft rubber OEM bushings and will transmit more feedback from the road, through tires and up to the steering wheel and through the chassis. You will feel more noise, vibration and harshness, but nothing that would prevent your Evo from being daily drivable. Whiteline bushing kits include items shown in pictures plus grease for use during installation.
