Description

AST Half Roll Cage Nissan Silvia S14 Coupé V1

The Half Roll Cage S14 V1 is a half roll cage for the Nissan Silvia S14 Coupé: a four-point structure that occupies only the rear compartment. The main hoop rises behind the seats, with backstays running rearwards.

For many S14 drivers, this is the logical first step. You get a more rigid rear end and a hoop behind your head, without having to sacrifice the front of the interior. You can still get in and out normally and the car remains usable.

Key benefits

• Four-point half roll cage: protection and rigidity at the rear, without modifying the front compartment.
• Headlining option: when ordering, you specify whether the cage needs to allow for the headlining or whether the roof is bare.
• Mounting zone option: when ordering, you specify whether the cage is anchored at the rear in the suspension area or at the wheel arch.
• X-shaped rear structure: the rear section is braced in an X.
• E355 steel: main hoop with a diameter of 45 mm, the rest of the structure 40 mm.
• Custom reinforcement plates: 3 mm thick steel, designed for each specific car rather than as a universal part.
• Exact fit: the bodyshell is digitised with laser scanners before the cage is designed in 3D.
• Supplied unpainted: you choose the finish yourself.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. The four foot plates are welded to the bodyshell, after which the cage is bolted onto them. Welding these plates is part of the fitting and requires an experienced welder. The rear seats and the rear trim have to come out. This cage is intended for track and competition use; check the regulations of your own sporting body beforehand.

The first real step for an S14 that is going to be driven seriously, without making the car unusable.

Why choose this Half Roll Cage S14 V1?

An S14 that is drifted a lot starts to flex at the rear. Shock towers, boot and rear wings all take a beating. This cage ties those points together and puts a hoop behind your head at the same time. Because it sits only in the rear, the car stays practical: you get in normally and the dashboard stays where it is.

Frequently asked questions

What do I need to specify about the headlining?

When ordering, you choose whether the cage should suit a roof with headlining or a bare roof. This determines how closely the tubes follow the roof, so choose what matches your car.

What exactly is the mounting zone option?

You specify whether the cage is anchored at the rear in the rear suspension area or at the wheel arch. Both are available for this Half Roll Cage S14 V1; which one you choose depends on how your boot is laid out and what your regulations require.

Is this half roll cage welded in?

The four foot plates are welded to the bodyshell. The cage itself is bolted onto them.

Can the rear seats stay in?

No. The main hoop goes where the rear seats are.

The standard delivery time for this roll cage is 15 to 35 working days, as AST builds every cage to order.
