Whiteline Roll Center Adjuster (RCA) Kit for 2005 Subaru Impreza

Sold in sets (comes with left and right side parts when applicable).

Whiteline Roll Center Adjuster Kits are designed to fix the bump steer and excessive roll that can effect certain vehicles when they are lowered. Each RCA kit comes with all the parts needed to be able to correct the angle of the control arms, toe arms, or the tie rods to bring the geometry back into optimal alignment. Lowering a vehicle changes the static angle on the suspension components, which can in turn lower the vehicles roll center beyond the center-line of the wheel. This can cause excessive body roll even with upgraded swaybars. Lowered cars can also get severe angles on the tie rods and toe adjustment arms, which causes the toe to change when the car's suspension compresses or extends. This leads to a car that feels darty when the road isn't smooth. Whiteline Roll Center Adjusters correct this by using extended ball joints, tie rod ends, and re-designed bushings to bring the angles of the suspension arms back into OEM specs. Thereby making the bump steer and roll center optimal for the car again, even with significantly lowered suspension.
