HKS Cup Hipermax R Coilover Full Kit - 2022-2026 Subaru BRZ / Toyota GR86

Cup Hipermax R Coilover Full Kit for the 2022-2026 GR86 and BRZ

The HKS Cup Hipermax R Coilover Full Kit for the 2022-2026 Subaru BRZ and Toyota GR86 is HKS's dedicated cup racing coilover system for the second-generation platform, developed for competitive use in the HKS Cup racing series and equivalent club racing events. The Cup Hipermax R provides the spring rates, damper calibration, and setup adjustability required for competitive circuit racing, where suspension consistency and precise geometry control across a full session are the governing requirements.

Specs & Highlights

• Cup racing dedicated coilover system
• Spring rates and damping calibrated for competitive circuit racing
• Full adjustability for setup optimization
• Developed for HKS Cup racing series
• Height adjustable with independent damper adjustment
• Fitment: 2022-2026 Subaru BRZ / Toyota GR86

12/10 kgf/mm, 52mm Piston, Separate High/Low Speed Compression

The Cup Hipermax R uses 12 kgf/mm (672 lbf/in) front and 10 kgf/mm (560 lbf/in) rear spring rates, the highest in the GR86/BRZ HKS coilover lineup. The 52mm piston body provides the damping capacity the high spring rates require. Separate high/low speed compression adjustment plus rebound adjustment provide the setup flexibility needed for different circuit conditions. Ride height adjustment range is -25mm to -60mm at both axles. The Cup kit was developed alongside the HKS Cup racing series and is the specification used in that competition series.

Cup Racing Calibration vs Street or Track Day Coilovers

Cup racing coilover requirements are distinct from street and even track day requirements. The session-long consistency matters more than single-lap compliance. The coilover must maintain its calibration across multiple laps of hard driving without fading or shifting in character. The Cup Hipermax R is developed to this standard.

Developed for and Used in the HKS Cup Racing Series

This is a racing coilover for competitive use. Ride quality on public roads is firm. For dual-purpose builds that also need to drive to the track, the standard Hipermax R or HIPERMAX S provides a better balance. The Cup Hipermax R is for cars that are primarily used in a competitive context.

The FT Breakdown

The Cup Hipermax R is HKS at its most track-specific for the second-generation GR86 and BRZ platform. If you are racing the car, this is the coilover HKS developed for that purpose. The engineering comes from the same program that campaigns the car in their own racing series. The 12/10 kgf/mm specification at 52mm piston body is what it takes to make a 1,270 kg car respond consistently across a full circuit racing session under the lateral loads that competitive lapping generates. The Cup Hipermax R is not a street car with a stiff ride — it is a racing coilover that can be driven to the track. Those are different things.
