HKS 19.8N/MM Helper Spring Set for 2013-2021 Toyota 86, Subaru BRZ, Scion FR-S
The HKS 19.8N/mm Helper Spring Set installs with HKS Hipermax coilovers to hold consistent preload on main springs. Designed for 2013-2021 Toyota 86, Subaru BRZ and Scion FR-S models, these springs prevent sagging at ride height for reliable suspension action. Drivers gain sharper turn-in and stable cornering on street or track.
Key Features
- 19.8N/mm Spring Rate: Matches HKS coilover tuning for even load distribution and prevents main spring bottoming under light compression
- High-Tensile Steel Build: Resists fatigue over long-term use while keeping precise coil spacing
- 85mm Free Length: Provides ample travel support without limiting damper stroke in Hipermax systems
- Direct HKS Compatibility: Bolts on with factory-spec inner diameter for 60mm coilover struts
- Pair Quantity: Complete set for front or rear axle replacement to restore full suspension performance
Product Notes
- Inspect coilover perch alignment before install to ensure level seating
- Clean springs regularly to avoid debris buildup affecting preload
- Ships in protective sleeve to prevent bending during transit
Installation Notes
