AST Weld-in Roll Cage Nissan Silvia S14 Coupé V4

The Weld-in S14 V4 is a full roll cage with eight welded mounting points for the Nissan Silvia S14 Coupé, with front reinforcement bars, door bars, an extra diagonal brace and a harness bar. It is supplied as a weld-in kit and permanently welded in.

The harness bar is the practical difference from the V3. Your shoulder straps get a fixed point at the height the regulations require, instead of a mounting in the bodywork that you cannot be sure of in an impact.

Key benefits

• Harness bar: a fixed anchorage point for the shoulder straps of your harness.
• Extra diagonal brace: more torsional rigidity in the rear structure.
• Door bars: side protection alongside the driver.
• Eight welded mounting points: the cage is permanently welded to the bodyshell.
• Front reinforcement bars: the structure continues through to the bulkhead.
• 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.
• Exact fit: the bodyshell is digitised with laser scanners before the cage is designed in 3D.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. All of the rear interior trim comes out, as do the dashboard and the door cards. Set your seat position in relation to the harness bar before any final welding is done. This cage is intended for track and competition use; check the regulations of your own sporting organisation beforehand.

Eight welded mounting points, door bars and a harness bar: the version that makes an S14 count as a competition car.

Why choose this Weld-in S14 V4?

As soon as you drive with four-point or six-point harnesses, you want a bar to attach those belts to. This version provides one, on top of the door bars and the welded-in structure. It is the specification most drift cars end up with: complete enough for competition, without going straight to the full set of bars of the V5.
