Less droop on fast, smooth, low to medium grip tracks can be faster.
More droop jumps and lands better, and is more forgiving to drive.
On high grip, running a lot of droop make the car easier to drive and less likely to flip over.
With Tires:
We do not suggest comparing downtravel by shock length as this cannot be compared with different shock positions.
