Cusco OS Front Strut Bar for FC3S Mazda RX-7 (1986-1991)

Improve the handling and steering response of your FC3S Mazda RX-7 (model years 1986-1991) with the Cusco OS (Open Shaft) Front Strut Bar. This high-quality component connects the vehicle's front strut towers, significantly increasing torsional rigidity and reducing chassis flex during cornering and braking.

Key Features and Benefits:

  • Enhanced Front-End Rigidity: By linking the left and right strut towers, this bar minimizes chassis flex, leading to a more stable and predictable front suspension.
  • Improved Steering Precision: A stiffer chassis allows the steering system to transmit inputs more directly, resulting in sharper turn-in and a more connected feel to the road.
  • Reduced Body Roll: While primarily a chassis brace, it contributes to flatter cornering by limiting the independent movement of the front suspension mounts.
  • Lightweight OS Design: The 'Open Shaft' design utilizes a lightweight yet strong aluminum shaft, minimizing added weight while providing excellent stiffness.
  • Direct Bolt-On Fitment: Engineered specifically for the FC3S RX-7 chassis, this strut bar installs directly onto the factory strut tower mounting points without requiring modifications.
  • Durable Cusco Quality: Manufactured by Cusco, a globally recognized leader in performance automotive parts, ensuring reliability and lasting performance.

The Cusco OS Front Strut Bar is an essential upgrade for any FC3S RX-7 enthusiast looking to refine their vehicle's handling characteristics. Whether for spirited street driving or track applications, this brace offers a noticeable improvement in chassis control and driver confidence. Get yours today from GGCRACING.
