Description

Built to meet Formula Drift specifications, the G35 Coupe FD Spec Roll Cage with X Door Bars is designed for competition-focused builds that retain some OEM interior elements. This non-gutted configuration allows the use of trimmed factory door panels and operational windows, striking the perfect balance between function and performance.

The X-style door bars offer superior side impact protection and frame stiffness while still clearing modified door interiors. All tubing is CNC notched, mandrel bent, and laser-etched to streamline the installation process and ensure precise alignment throughout the cage.

This is a weld-in kit that rewards patience and attention to fitment. The more care taken during mock-up, the better the final result.
