Front and rear suspension are much closer in terms of how they handle bumps, particularly noticeable with mid-corner bumps. My 17 front suspension would soak it up and then it would hit the rear and break traction. The 21 rear is much more settled, probably as much as we can get without independent rear.
I'm looking forward to some more seat time when I can test the sport and off-road suspension settings on the same stretch of road. Sport does reduce body roll, but haven't been able to see how it reacts to bumps (mid-corner or otherwise).
