I disagree (to a degree). With a semi-trailing arm suspension, the roll center is defined by the angle generated by both mounts. Raising the inner mount will raise the roll center, even if you don't change to the shorter Turbo trailing arms. The Turbo Trailing arms were designed to do this AND increase the camber gain curve by virtue of the shorter swing arm. But the two affects can and sometimes are separated by using an adjustable trailing arm mount as shown in this picture.



Depending on how they are installed, they can be used with or without Turbo trailing arms. In the photograph they were used with Turbo trailing arms.
