Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. The door bars reduce the room for getting in and out, so take the position of the seat and harness into account when building up the car. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that it fits your car exactly.

With the door bars added, the driver is enclosed on all sides, not just above and behind.

Why choose this Full roll cage E46 Coupé V3?

A side impact is a real scenario on track and in drifting, especially in tandem runs. The door bars in this version absorb that load before the door reaches the driver. That is the difference between a cage that mainly provides rigidity and a cage that truly protects you.

Frequently asked questions

What has been added compared with the V2?

The full roll cage E46 Coupé V3 has door bars that the V2 does not have. The rest of the structure, including the front reinforcement bars and the six bolting points, is the same.

Can I still get in and out normally?

The door bars make the opening narrower. That is a deliberate choice in favour of more protection; for those looking for more room to get in and out, AST also designs NASCAR door bars for other models.

Is this roll cage homologated?

The manufacturer’s documentation does not list a homologation number for this item. The cage is intended for track and competition use; check the regulations of your own motorsport organisation before you enter.

What is the delivery time?

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