Description

AST Multipoint Weld-in Roll Cage Nissan Silvia S15 Coupé V3

The Multipoint S15 Coupé V3 is a full roll cage from AST Roll Cages for the two-door Nissan Silvia S15, welded to the bodyshell at ten points.

This version brings door bars into the picture. In an S15 that is no minor detail: the car is narrow and the distance between your shoulder and the door is small. A door bar welded directly into the pillars keeps that space intact in a side impact.

Note that AST builds the rear structure here in a V design, whereas the V2 has an X design. The cage is supplied unpainted.

Fitting and delivery

Decide first which bucket seat is going in, because the door bars and the seat together determine how much shoulder room you are left with. The original door card usually no longer fits once the cage is in. After that, it is the usual routine: strip the car, take the ten welded mounting points back to bare metal, weld.

Each cage is custom-built after you order. The delivery time is 15 to 35 working days.

Ten welded mounting points under the car and steel between you and the door.

Why choose this Multipoint S15 Coupé V3?

For many organisers, door bars are the threshold above which a cage counts as a serious safety feature. In this ten-point version, you get that protection on top of an anchorage that is already spread across the entire chassis. Because AST scans the S15 bodyshell beforehand, the door tubes follow the shape of the door instead of cutting straight across it.

Frequently asked questions

Is this a half or a full roll cage?

A full roll cage, welded at ten points and extending into the front compartment.

What is the difference from V2?

The Multipoint S15 Coupé V3 has door bars in both doors and a rear structure in a V design. The V2 has no door bars and an X design.

Can I keep my original door cards?

Usually not. Expect to use modified or lightweight panels.

Why a V design and not an X design?

AST specifies a V design rear structure for this item. This is fixed during construction and is not an option when ordering.

Is this roll cage homologated?

AST does not list an FIA homologation number for this item. Assume track and competition use and check the regulations of your own organiser.
