AST Bolt-in Roll Cage BMW F30 Sedan V3

The AST Bolt-in Roll Cage BMW F30 Sedan V3 is a full roll cage for the BMW 3 Series F30 with 4-door saloon bodywork. In addition to the main hoop and the front reinforcement bars, this bolt-in F30 Sedan V3 also has door bars in both doors for side protection.

The cage is designed and built by AST Roll Cages in Spain, for drivers who want a complete structure that goes into the car in sections and is then bolted in place.

Key benefits

• Door bars: the V3 adds side bars to the package of the V2, improving protection in a side impact.
• Six bolting points: the cage bolts onto six foot plates that are welded to the bodyshell.
• Fitted in sections: connecting sleeves divide the structure, so the cage can go in through the door opening.
• Full chassis reinforcement: the cage runs from the bulkhead to the rear of the car and makes the bodyshell noticeably more rigid.
• E355 steel: 45 mm main hoop, 40 mm for the remaining tubes.
• 3 mm foot plates: custom-designed car by car for the F30 saloon.
• Complete package: bolts, washers, nuts, reinforcement plates, documentation and a sticker set are included.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. The six foot plates are first welded to the bodyshell; you then bolt the cage onto those plates. So you will need a welder at some point in the process, even though this version is called bolt-in. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that it fits your car exactly.

A full cage with door bars that can be fitted in sections and taken out again.

Why choose this bolt-in F30 Sedan V3 roll cage?

The V3 is the point at which an F30 truly becomes a track car: the door bars protect you when running side by side on track, and the six points spread the loads across the entire bodyshell. Because the structure is removable, you can take it back out of the car if you move or sell it. The cage is intended for track and competition use; check the regulations of your own organiser before you enter.

Frequently asked questions

Can I fit this cage without welding?

No. The six foot plates of this bolt-in F30 Sedan V3 are welded to the bodyshell. Only the cage itself is then bolted onto those plates; that is what the term bolt-in means here.

Does AST also offer a NASCAR version for the F30?

No. AST’s range does not include any NASCAR variants for the BMW F30 saloon. Here you choose between the bolt-in and the weld-in options in the versions available.
