I have a little experience with suspensions mostly on sport and muscle cars. I would say that the reduction in lean on corners would be due to the rear anti-sway bar. The shock absorbers aid mostly in reducing vertical rebound.
Newell is installing the RK shocks for me.
I also experienced the body leaning/rolling with original shocks with dips on the sides of the lanes and corners which feel VERY uncomfortable. I keep telling myself the center of gravity is low and it won’t tip over... if the coach leans/rolls to the side it wants to track in that direction or feels like that. It does have a sway bar so the shocks should help.
Safe-T-Plus is coming out with a unit for the ZF suspension. I’m interested in hearing what they have to say about that unit and how they tested it.
