As I’ve mentioned, I have an SS 1LE with the DSSVs and other Z arms and bushings. So it’s not a comparison to the Z mostly because of the Z’s substantial reduction of unsprung weight. That less unsprung weight will affect the chassis more than anything. My experience with the full Z suspension vs the DSE Speed Kit 1 on track is that the car is just a tiny bit slower to respond to transitions/quick directions. This most likely won’t be felt with street driving.

I mentioned my change from the DSE front ARB to the 1LE front ARB. I do now believe that the 1LE bar is stiffer than the DSE bar. This has increased responsiveness and steering feel. On the track there is less body roll. Because I felt that I increased the understeer of the front due to the stiffer 1LE bar, I increased the stiffness of the rear DSE bar, only slightly. I have one side of the bar in the middle hole, and the other side full stiff. The result at the last track day was amazing. The car would rotate on throttle from the center-off.
