AST Weld-in Roll Cage Nissan Silvia S15 Coupé V5

The Weld-in S15 Coupé V5 is a full roll cage from AST Roll Cages for the two-door Nissan Silvia S15 and the highest specification level in the eight-point weld-in range for this car.

Everything AST designs for the S15 is included: front reinforcement bars to the bulkhead, door bars in both doors, the extra diagonal brace in the main hoop and the harness bar behind the seats. If you already know that your car will eventually go to this level, the V5 gets you there in one go, and you won’t have to weld in extra bars later in a finished interior.

The rear structure has a V design. The cage is supplied unpainted.

Fitting and delivery

This is the most extensive weld-in kit in the range, so set aside the most time for it too. Work from the outside in: first the main hoop and the rear anchorage, then the front bars, and only after that the door bars and the harness bar. Decide on the seat position before anything is permanently fixed.

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

Everything AST designs for the S15, in one go and welded in for good.

Why choose this Weld-in S15 Coupé V5?

Welding extra bars into a car that is already finished is the kind of job nobody enjoys: the interior back out, the wiring tucked away again, the paintwork redone. If you have ambitions to compete with your S15, you can skip that second round by having the complete package fitted straight away. You pay more up front and save yourself a complete strip-down later.

Frequently asked questions

Is this a half or a full roll cage?

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

What does the V5 have that the V4 lacks?

The Weld-in S15 Coupé V5 has the full set of bars. The V4 does have the diagonal brace and the harness bar, but not the full set of bars that the V5 includes as standard.

How much interior space is left?

Less than with the lower versions. Expect bucket seats, modified door cards and a rear seat that has to come out.

What layout does the rear structure have?

This version has a V design rear structure.

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.
