AST Weld-in Roll Cage Nissan Skyline R33 Coupé V1

The AST Weld-in Roll Cage Nissan Skyline R33 Coupé V1 is a full roll cage for the Nissan Skyline R33 with two-door coupé body, welded to the body at eight points. This Weld-in Roll Cage R33 V1 is supplied as a welding kit and welded into one unit in the car.

A weld-in cage spreads the forces over the whole body instead of over a few bolt points. That makes it stronger than a bolt-in cage, and for many competition classes it is the required version. The V1 is the entry model: the basic structure without extra bracing at the rear.

Key benefits

• Eight weld points: the cage is welded to the body in eight places.
• Stronger than bolt-in: the forces are spread over the whole body.
• Anchored up to the wheel arch: the rear stays run to the wheel arch.
• Gussets included: to reinforce the joints.
• E355 steel: 45 mm diameter main hoop, 40 mm for the rest of the structure.
• Custom base plates: 3 mm thick steel, designed per car rather than universal.
• Exact fit: the body is digitised with laser scanners before the cage is drawn in 3D.
• Complete kit: supplied unpainted with fixings, documentation, installation manual, sticker set and welding test sample.

Installation and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. It comes as a welding kit and is welded into one unit in the car. Leave the welding to someone with experience in roll cages: the included welding test sample is meant to check beforehand that the welding settings are right. On a R33 of this age, check beforehand that the mounting areas are free of rust: welding onto corroded panels gives a cage that will not do its job in a crash. This cage is intended for circuit and competition use; check the regulations of your own motorsport organisation beforehand.

Eight weld points and a complete structure: the basis for a R33 that is really going racing.

Why choose this Weld-in Roll Cage R33 V1?

For anyone building the R33 into a dedicated circuit or competition car, a weld-in cage is the strongest choice. The V1 gives you that basis at the lowest price of the weld-in range, and leaves room to have extra braces welded in later.

Frequently asked questions

What is the difference with a bolt-in cage?

A bolt-in cage is bolted in on six points and can come out again. This Weld-in Roll Cage R33 V1 is welded in on eight points and is therefore stronger, but stays in the car permanently.

Can I weld the cage in myself?

Only if you have experience welding roll cages. A poor weld takes the strength out of the structure. If in doubt, leave it to a specialist.

Does this cage also fit an R33 sedan?

No. This cage is designed for the two-door coupé. The four-door sedan has a different rear body structure.

Does it fit a GT-R?

Yes, as long as it is an R33 coupé. The cage sits in the interior and has nothing to do with the four-wheel drive of the GT-R.

What is the delivery time?

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