Description
The S13 Road Race Non-Gutted Roll Cage Kit with X Door Bars is engineered for competitive road racing and designed to meet NASA tech requirements. The main structure of the cage is made from 1.75″ x .095″ / .120″ DOM steel tubing, which includes the Main Hoop, Front Top Bar, Rear Down Bars, and A-pillars. The supporting structure, such as door bars, door bar supports, gussets, and FIA bars, is crafted from 1.5″ x .095″ DOM steel tubing to ensure a lightweight yet rigid setup.
The X-style door bars provide maximum side impact protection, which is essential for road race environments. The non-gutted design requires trimming of the factory door panels but retains enough material to maintain functional windows—ideal for a balance of interior comfort and track safety.
CNC notched and mandrel-bent tubing ensures that each tube fits precisely, making the assembly process quicker and easier. The laser-etched fitment guides simplify the installation process, allowing for accurate tube placement and reducing install time.
This weld-in roll cage kit requires skilled installation. Proper fitting and measurement are essential to achieving the best alignment and ensuring structural integrity.
