Description
The HKS HIPERMAX S coilover kit provides adjustable damping and ride height for the Toyota GR86 ZN8. This configuration uses front pillow-ball upper mounts and rubber rear upper mounts.
Design and operation
The front and rear dampers each offer 30-step damping adjustment. Front dampers use an inverted layout and the rear dampers use a conventional layout. Height-adjustable lower brackets provide a separate means of setting the installed suspension length.

Installation and selection

Set ride height for usable travel and tire clearance, then complete a four-wheel alignment.
