AST Bolt-in Roll Cage Nissan Silvia S14 Coupé V3

The Bolt-in S14 V3 is a full roll cage for the Nissan Silvia S14 Coupé with six bolting points, front reinforcement bars and door bars. It is the first version in the bolt-in range that also provides side protection.

The side is where things go wrong in drifting. A tap against the wall or another car almost always lands on the flank, and the door of an S14 has little to offer there on its own. This version puts steel in between.

Key benefits

• Door bars: side protection alongside the driver.
• Front reinforcement bars: the structure continues through to the bulkhead.
• Six bolting points: on six foot plates welded to the bodyshell.
• FIA connecting sleeves: the cage can be taken out of the car in sections.
• V-shaped rear structure: the rear section is laid out as a V.
• 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.

Suitable for

Nissan Silvia S14, 2-door coupé

• Nissan Silvia S14 Coupé, known in some markets as the 200SX or 240SX
• Type: full roll cage, bolt-in, version V3
• Drifting, track use and competitions

This cage is designed around the two-door S14. This version anchors in the rear suspension area and is made for a roof without a sunroof and without headlining. Bear in mind that door bars make getting in and out more awkward.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. The six foot plates are welded to the bodyshell, after which the cage is fitted onto them in sections. For the door bars, the door cards have to come out and you will need to set your seating position again. This cage is intended for track and competition use; check the regulations of your own motorsport governing body beforehand.

With door bars added, the door of the S14 is finally more than a thin piece of sheet metal.

Why choose this Bolt-in S14 V3?

Anyone who gets serious about drifting will sooner or later make side contact with something hard. The V3 is the point in this range where that scenario is taken seriously, with door bars alongside the driver and front bars to the bulkhead. Because it remains a bolted cage, you can take the structure out again later if the car’s build changes.

Frequently asked questions

What does the Bolt-in S14 V3 add compared with the V2?

Door bars. The V2 does not have them, the V3 does.

Can I still refit the original door card?

Usually not without modification. Expect to have to modify the trim or leave it out.

Is any welding required?

Yes, at the six base plates. The cage itself is bolted onto them and remains removable.

Is there a version with even more tubes?

Yes, the V4 from the same range adds an extra diagonal brace and a harness bar.

What is the delivery time?

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