HKS 83003-KT004 Yamaha Performance Damper for 2013-2025 Toyota 86 / Subaru BRZ

Vehicle Fitment

• 2013-2020 Subaru BRZ (Base, Limited, Premium, Sport, Series.Gray, Series.Yellow, tS - ZC6 Chassis, FA20, RWD)
• 2017-2020 Toyota 86 (Base, GT, Limited - ZN6 Chassis, FA20, RWD)
• 2013-2016 Scion FR-S (Base, Series 1.0, Series 2.0, Release Series - ZN6 Chassis, FA20, RWD)
• 2022-2025 Subaru BRZ (Base, Limited, tS - ZD8 Chassis, FA24, RWD)
• 2022-2024 Toyota GR86 (Base, Premium - ZN8 Chassis, FA24, RWD)

Fitment Notes

• This damper is a chassis-mounted vibration damper - it does not replace or interact with coilovers or shock absorbers. It is compatible with both stock and aftermarket suspension setups.
• Performance characteristics are best realized when paired with the HKS HIPERMAX S suspension kit, as the combined system creates an optimally balanced ride and handling improvement.
• The ZC6 (2013-2020 BRZ) and ZN6 (2013-2020 Toyota 86 / Scion FR-S) are first-generation platforms sharing the FA20 boxer engine. The ZD8 (2022-2025 BRZ) and ZN8 (2022+ GR86) are second-generation platforms using the updated FA24 boxer engine.
• MSRP: $990.00 USD

Features

• Yamaha Performance Damper® technology licensed from Yamaha Motor Co., Ltd. and tuned by HKS specifically for the 86/GR86/BRZ platform
• Operates on a micrometer displacement scale - absorbs and dissipates chassis micro-vibrations caused by road surface input, tire feedback, and body flex
• Reduces body flex and unwanted chassis play, improving torsional rigidity feel without structural modifications
• Suppresses micro-vibrations transmitted through the frame, reducing in-cabin noise, vibration, and harshness (NVH) for a more refined driving environment
• High-pressure nitrogen gas-charged oil damper design with ultra-low piston speed characteristics and cancelled gas reaction force - no pressurization on the chassis
• Vehicle-specific tuning by HKS ensures optimal damping properties (saturation characteristics) for the ZC6/ZN6/ZD8/ZN8 platforms
• Direct bolt-on installation - no cutting, welding, or modification required

Product Description

The HKS 83003-KT004 is the Yamaha Performance Damper® for the Toyota 86, GR86, Scion FR-S, and Subaru BRZ - a precision chassis damper licensed from Yamaha Motor Co., Ltd. and tuned by HKS specifically for the ZC6, ZN6, ZD8, and ZN8 platforms. Unlike conventional suspension components, this damper operates at a micrometer displacement scale, targeting the chassis micro-vibrations that travel through the body from road surface input, tire noise, and structural flex. By absorbing and dissipating these minute forces at the chassis level, it reduces body looseness and unwanted play, resulting in handling that feels simultaneously sharper and smoother - allowing the driver to trace intended lines more precisely without fighting vagueness in the chassis.

Beyond handling, the Performance Damper suppresses NVH (Noise, Vibration, and Harshness) transmitted through the frame into the cabin, improving interior refinement and reducing driver fatigue on long drives. The damper is engineered with optimized saturation characteristics and cancelled gas reaction force, ensuring no additional pressurization is placed on the chassis structure. Installation is direct bolt-on with no modifications required, and the unit is compatible with stock or aftermarket suspension setups. HKS recommends pairing it with the HIPERMAX S coilover kit for the most balanced and complete improvement to both ride quality and handling response.
