AST Full Roll Cage Nissan Silvia S15 Coupé V2

The Full Roll Cage S15 V2 is a full roll cage from AST Roll Cages for the two-door Nissan Silvia S15, built from sections that are joined together with connecting sleeves and secured at six bolting points.

Compared with the V1, this version adds the front reinforcement bars, which run from the A-pillar to the bulkhead. This makes the front end of the S15 contribute to the rigidity of the whole structure instead of doing its own thing. On a circuit with quick changes of direction, that is the difference between a car that holds its line cleanly and one that wanders.

The cage is supplied unpainted.

Fitting and delivery

The six foot plates are welded to the bodyshell, after which the cage is bolted onto them. The front bars need a little extra thought, because they run past the dashboard to the bulkhead and share space there with the wiring loom and the heater box. Measure this carefully before you fix the foot plates for good.

Every cage is custom-built after you order, with a delivery time of 15 to 35 working days.

The step that stops the front of your S15 from doing its own thing.

Why choose this Full Roll Cage S15 V2?

The S15 is a nicely balanced car in its own right, but under heavy loads the front end flexes. By extending the cage to the bulkhead, you spread those forces across the whole structure instead of leaving them in the panels. And because the cage is built with connecting sleeves, you don’t have to pay for that gain with a construction that can never come out again.
