Description
The HKS HIPERMAX D NOB Coilover Kit provides a defined suspension configuration for controlling ride height and chassis movement. Application: Nissan Silvia (S15).
Design and operation
Spring rates establish the suspension’s load response, while damper settings control how quickly the suspension moves. Selecting the correct kit involves balancing usable suspension travel, tire clearance and the vehicle’s intended driving conditions.
Technical details
- Manufacturer part number: 80015-AN103.
- Application: Nissan Silvia (S15).
- Full-kit spring rates: front 78 N/mm (8 kgf/mm); rear 59 N/mm (6 kgf/mm).
