Improve the handling characteristics and overall driving refinement of your Toyota 86, GR86, or Subaru BRZ with the HKS Performance Damper (83003-KT004). Designed with Yamaha Performance Damper technology and tuned by HKS, this chassis upgrade helps reduce unwanted body flex, vibrations, and chassis movement to provide a more stable, responsive, and confidence-inspiring driving experience.

Unlike traditional suspension upgrades that focus on increasing stiffness, the HKS Performance Damper is engineered to absorb and control subtle chassis vibrations and flex caused by road imperfections, cornering forces, and steering inputs. The result is improved vehicle balance, sharper handling response, enhanced ride quality, and a more refined feel during both spirited driving and everyday use.

Designed specifically for the Toyota 86, Subaru BRZ, and GR86 chassis platforms, the HKS Performance Damper provides a factory-like upgrade that enhances vehicle dynamics without sacrificing comfort or daily drivability.

Why Choose the HKS Performance Damper?

The lightweight sports-car platforms of the Toyota 86, GR86, and Subaru BRZ are known for their exceptional balance and driver-focused handling. However, even these chassis can experience flex and vibration during aggressive cornering, rough road conditions, and high-performance driving.

The HKS Performance Damper works by controlling low-level chassis movement and absorbing unwanted vibrations before they reach the driver. This allows the suspension system to operate more effectively while improving overall vehicle stability and refinement.

Benefits include:

• More precise steering feel
• Improved cornering confidence
• Reduced chassis vibration
• Better ride quality on uneven roads
• Increased stability during high-speed driving
• Enhanced connection between driver and vehicle

Whether you drive your BRZ or 86 on the street, canyon roads, autocross courses, or track days, the HKS Performance Damper provides a refined improvement in chassis performance.
