AST Removable Half Roll Cage BMW G80 Sedan V2

The AST Removable Half Roll Cage BMW G80 Saloon V2 is a half roll cage for the BMW 3 Series G80 with 4-door saloon bodywork. This removable half cage G80 Saloon V2 builds on the V1 and has a more extensive tube structure around the rear compartment, for drivers looking for a step up in rigidity.

The cage is designed and built by AST Roll Cages in Spain, for racers and drifters who use their G80 seriously but do not want to modify the car permanently.

Key benefits

• More tubing than the V1, giving the rear section of the bodyshell extra support.
• Removable via connecting sleeves, so the car can be returned to its original condition.
• Four welded foot plates in 3 mm steel that spread the load across the bodyshell.
• 45 mm main hoop in E355 steel, with the rest of the structure in 40 mm.
• Nothing in the way up front, as the design is confined to the rear compartment.
• Custom-designed for each car from a digital laser scan of the bodyshell.
• Supplied unpainted, ready for your own colour scheme.
• Available for cars with and without headlining – you choose this when ordering
• Available with anchorage in the rear suspension area or in the boot area, which you choose when ordering

Fitting and delivery

Why choose this removable half cage G80 Sedan V2?

Where the V1 covers the essentials, the V2 goes a step further with additional tubing around the rear compartment. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that it fits your car exactly. You also keep the advantage that the cage remains removable.

Frequently asked questions

What is the difference from V1?

The removable half cage G80 Sedan V2 has a more extensive tube structure than the V1 and, according to the manufacturer’s figure, weighs the same: 71 kg. The mounting principle with four welded foot plates is identical.

What exactly will I receive?

You receive the welded structure, the connecting sleeves, reinforcement plates, bolts, washers and nuts, documentation, fitting instructions and a sticker set. The cage is unpainted so you can finish it yourself.

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

A G80 is packed with electronics and airbag systems, so fitting a cage in such a modern car needs careful planning. Have it worked out in advance which trim and components need to come out, and check the regulations of your own organiser, as they determine what is permitted in your class.

What if my car has headlining?

When ordering, please state whether the headlining will stay in your car, and AST will tailor the roll cage accordingly.

Where is the roll cage anchored at the rear?

You choose this yourself when ordering: in the rear suspension area or in the boot area. AST builds the rear foot plates for the area you specify.

What is the delivery time?

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