Sold individually. Must purchase qty 2 to install.
Roll center adjusters (RCAs) help in two ways on a lowered car: they reduce chassis roll, and they reduce bump steer from angled tie-rods. As the car is lowered, the invisible point where the center of gravity acts on the car while cornering (the roll center) is lowered as well. This causes the car's center of gravity to put more leverage on the roll center, causing more body roll. The tie rods also become angled upwards, causing noticeable bump steer as the tie rod articulates.
