AST Half Roll Cage Nissan GT-R R35 Coupé V2

The Half Roll Cage R35 V2 is a half roll cage for the Nissan GT-R with the R35 chassis in 2-door Coupé bodywork. Where the V1 sticks to a main hoop with backstays, the V2 adds extra tubes, so the rear is tied to the bodyshell over a larger area.

The four bolting points sit on foot plates that are welded to the bodyshell at the wheel arch. That is where the rear suspension of this all-wheel-drive coupé has to transfer its loads.

This is the more substantial of the two half-cage levels for the R35, and the logical choice if you do a lot of track mileage but want to keep the front compartment standard.

Key benefits

• Extra tubes compared with the V1, so more connection between the main hoop and the bodyshell.
• Four bolting points on four welded foot plates made of 3 mm steel.
• Anchorage at the wheel arch, with a short load path to the rear suspension.
• E355 steel, 45 mm main hoop and 40 mm for the rest of the structure.
• X design at the rear, a cross that braces the rear end diagonally.
• Designed from a laser scan, so no trial fitting or cutting in the car.
• Supplied unpainted, ready for you to have it blasted or powder-coated.
• Headlining option, you specify what your car has when ordering.

Fitting and delivery

AST builds this cage to order, with a delivery time of 15 to 35 working days. The four foot plates are first welded to the bodyshell, after which the structure is bolted onto them. That is a job for a fabricator who knows how to tackle a boot floor and a wheel arch. The dimensions come from a laser scan of the car, which makes fitting considerably quicker than with a universal cage.

As much rear structure as a half cage can offer, without changing a single thing up front.

Why choose this Half Roll Cage R35 V2?

An R35 that sees frequent track use has to cope with high, repeated loads on the rear axle. The V2 tackles this with extra tubes that spread the loads over more points than the V1 does. You stay in the half-cage segment, so the car keeps its normal entry and exit and its front interior, while rigidity around the rear axle takes a clear step forward.

Frequently asked questions

What does V2 offer compared with V1?

Extra tubes and therefore more attachment points on the bodyshell. If you notice the rear lagging behind in fast sequences of corners, this Half Roll Cage R35 V2 is the better choice.

Is any welding required?

Yes. The four foot plates are welded to the bodyshell; only the cage itself is then bolted in place. Fitting without welding is not possible with this version.

Where does the cage anchor at the rear?

At the wheel arch. AST positions the foot plates in that area, so the structure connects directly to the part of the bodyshell that carries the rear suspension.

What if my car has headlining?

When ordering, please state whether the headlining is staying in. AST adapts the tube routing accordingly.

Is this roll cage homologated?

The manufacturer’s documentation for this item does not show a homologation number. So treat the cage as track and competition equipment and check the regulations of your own organiser.

What is the delivery time?

The standard delivery time for this roll cage is 15 to 35 working days.
