Description
AST Weld-in Roll Cage Nissan Almera N15 3-door Hatchback V4
The Weld-in Roll Cage Almera V4 is a full, permanently welded-in roll cage for the Nissan Almera N15 3-door hatchback and one of the heaviest versions in the weld-in range. AST Roll Cages custom-builds this 8-point weld-in cage using laser scanning and 3D design, and supplies it as a weld-in kit.
Compared with the V3, the V4 adds an extra diagonal brace and a harness bar. The harness bar provides a fixed anchor point for the harnesses, and the diagonal further increases rigidity.
