AST Multipoint Weld-in Roll Cage BMW G80 Sedan V4

The cage is designed and built by AST Roll Cages in Spain, for drivers who want to spread the loads over as many mounting points as possible.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. Ten welded mounting points mean more welding and more preparation than with a standard weld-in cage, so expect a longer fitting time.

Ten welded mounting points spread the loads over a larger part of the bodyshell.

Why choose this Multipoint G80 Saloon V4 roll cage?

With two extra mounting points compared with a standard weld-in cage, the load is spread more evenly across the bodyshell. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that it fits your car exactly. For a G80 that covers a lot of kilometres on track, that is a difference you will see in the bodywork over time.

Frequently asked questions

What makes a multipoint cage different?

The Multipoint G80 Saloon V4 is welded to the bodyshell at ten points, where a standard weld-in cage uses eight. As a result, the loads are spread over a larger area.

What is included in the delivery?

The weld-in kit, gussets, reinforcement plates, bolts, washers and nuts, documentation, fitting instructions and a sticker set. AST scans the bodyshell with laser scanners so that the kit is tailored to your model.

What should I bear in mind with a modern car like the G80?

The G80 is packed with electronics and airbag systems, so fitting a cage to such a modern car needs careful planning, especially with ten welded mounting points that require the car to be stripped right down. Also check the regulations of your own organiser before you order.

What is the delivery time?

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