• This body reinforcement brace uses a carbon shaft manufactured by GRAPHITE DESIGN, a leading company in carbon shafts for golf.
• A carbon brace bar is added to connect the left and right front struts to increase rigidity, and the carbon material has a vibration damping effect to reduce unpleasant vibrations.
• Not only does it eliminate the unpleasant stiffness that can easily occur with metal reinforcement bars, but the carbon shaft absorbs unpleasant vibrations, resulting in a smooth, high-quality ride without any unpleasantness.

Development teams comment

• Without the carbon brace, steering lacked linearity and felt imprecise, making the car harder to control. On the track, this vague response made limit behavior unpredictable, reducing driver confidence.
• Installing the carbon brace improves steering linearity, delivering sharper feedback and a more connected driving experienceboth on road and circuit.
• For enhanced aesthetics and weight savings, we crafted the upper plate from machined aluminum with a hollowed outer perimeter.
• This marks the first time in the series weve designed it exclusively for front installation. As this is an FF (front-engine, front-wheel-drive) vehicle, the front brace alone provides significant benefits. A rear installation would require interior modifications without substantial performance gains, so we omitted it.”

Not just increasing strength, but also the necessity to emphasize flexibility.
Achieving both high strength and flexibility through joint development with a leading golf shaft company

• Enhanced rigidity without compromising ride comfort:HKS addressed the common concern of poor ride quality with general braces, by adopting high-quality carbon shafts with high strength and optimal flexibility, similar to those used in golf clubs.
• Developed in collaboration with GRAPHITE DESIGN, a renowned manufacturer of golf shafts favored by professional golfers, leveraging HKS’s extensive tuning expertise.
• Unmatched performance through carbon’s unique flexibility,made possible by GRAPHITE DESIGN’s expertise, delivering a level of control and performance that sets it apart from conventional brace bars.
• Improved driving dynamics:The flexibility not only enhances ride quality but also contributes togreater stability during circuit driving,amplifying the enjoyment of driving.

Torsion

• 150% increased torsional strengthcompared to stock brace bars, effectively reducing body torsion and enabling precise suspension movement.
• Enhanced damper response:Minimizes delays in suspension reaction, ensuring accurate and responsive handling.
• Optimized cornering stability:Torque increases progressively with angle, providing the necessary load at the right time for stable cornering performance.

Flexibility

• Improved flex characteristics:Utilizes carbon’s unique flexibility to reduce bending load to 70% or less compared to stock brace bars.
• Enhanced ride quality:Effectively absorbs unpleasant vibrations and sudden impacts, significantly contributing to a smoother and more refined driving experience.
