HKS Hypermax GR86/BRZ Cup Full Kit

HKS Hypermax GR86/BRZ Cup Full Kit - Toyota GR86 / Subaru BRZ (2022+)

Official Racing Series Spec - The Professional’s Choice for Circuit Dominance

Take your chassis to the professional level with the HKS Hipermax GR86/BRZ Cup Full Kit. This isn't just an "off-the-shelf" suspension; it is the specific, regulated kit used by professional drivers in Japan’s premier one-make racing series. Engineered to handle the increased power and grip levels of the 2.4L FA24 platform, the "Cup" kit features specialized valving and spring rates that have been refined through thousands of miles of competitive testing. If you want the exact same handling balance and high-speed composure found on the grid at Fuji Speedway, this is the definitive suspension system for your build.

What’s Included in the Box:

- Front & Rear Coilover Assemblies: Full-length adjustable dampers.

- Camber Adjustable Pillowball Front Top Mounts: For precision alignment tuning.

- Rear Top Mounts: Heavy-duty reinforced mounts for zero deflection.

- Adjustment Wrenches: HKS-branded spanners for height and preload tuning.

- Installation Hardware: Everything required for a professional-grade swap.

The HKS Cup Spec Advantage

- Series-Mandated Performance: Developed specifically for the GR86/BRZ Cup racing series, ensuring that every click of the 30-way damping adjustment provides a meaningful change in handling characteristics.

- Inverted Front Strut Design: Features an inverted monotube design in the front to maximize lateral rigidity. This prevents "strut flex" under heavy braking and high-G cornering, maintaining consistent alignment geometry.

- Competition Spring Rates: Tuned for the ZN8/ZD8 chassis weight distribution, providing the necessary roll stiffness to stay flat through high-speed sweepers while retaining enough compliance to soak up track curbing.

- Advanced PNE Coating: The shock bodies are treated with HKS’s proprietary PNE coating, offering 5 times more corrosion resistance than standard zinc plating. This ensures the adjustment threads remain smooth and functional even after seasons of track use.

- Dual PVS (Pre-load Valve System): Utilizes HKS's specialized valving to provide a more linear damping force, ensuring the tires stay glued to the track surface over bumps and undulations.

Precision Tip: This kit is designed for the serious driver. Because it uses pillowball mounts and higher spring rates, you will notice an increase in interior road noise and a significantly firmer ride. This is the trade-off for professional-level lap times. For the best performance, we recommend corner-balancing the car after installation and pairing this kit with the Cusco Adjustable Rear Lateral Arms we listed earlier to fully optimize your rear camber for the track.
