Cusco Japan engineers the strut-tower braces, sway bars, alignment correction, and limited-slip differentials that power JDM and time-attack programs. The brand behind countless Time Attack and grassroots motorsport podiums.
The Cusco OS Rear Strut Bar is the ultimate solution for reducing rear-end chassis flex in your Mazda RX-7 FC3S. By tying the rear strut towers together, this bar prevents the chassis from distorting under heavy cornering loads, allowing your suspension components to work exactly as intended. This results in sharper turn-in, improved rear-end stability, and a more connected feel between the driver and the road.
Designed to fit perfectly within the rear cargo area of the FC3S, the Cusco OS bar provides a rigid bridge that minimizes body roll and chassis flex. This is an essential upgrade for any enthusiast running stiffer suspension setups, as it helps manage the increased forces transferred to the chassis. By maintaining the structural integrity of the rear towers, you ensure that your alignment settings remain stable even during the most demanding driving conditions. Experience the difference in handling precision with this premium component from GGCRACING.
