Also you wouldn't run the PSS in the rear, not recommended so to speak.

We are able to run the higher roll centers because of the longer arms. This has generated more overall grip and corner speed. Running the higher roll centers using the short arms would make the car harder to drive and give the opposite affect that we are getting from the 20 and 21 model. We are discovering more ways to generate more traction and corner speed with the longer arms and the higher roll center is paying off.
