Point

We have developed a sport damper of MAX IV SP for Z33 from the scratch.
Plan 1. Changeable rear rate.
Plan 2. Easy damping force adjustment
To have rear stability for turn-in, we setφ65 series-wound spring with helper and enough bump stroke. Also we set the rear damping force adjustment dial inside the car for fast and easy setting, so that you don’t have to get your hands dirty (need interior works). We set it smooth but firm for the comfortable drive. It’s tight but not uncomfortable and there isn’t bad up and down movement. It also recovers fast.
Preferred dial setting
0-10: Circuit or high speed drive, 11 -20: Winding roads or highway, 21 – 30: Normal drive
We recommend spring rate of 14k for rear if you don’t go...
