AST Multipoint Weld-in Roll Cage BMW F87 Coupé V4 NASCAR door

The AST Multipoint Weld-in Roll Cage BMW F87 Coupé V4 NASCAR Door Bars is a full roll cage for the BMW 2 Series F87 with 2-door coupé bodywork. This Multipoint F87 Coupé V4 NASCAR combines ten welded mounting points with the full V4 bar package and curved door tubes, making it the most complete version in this line-up.

The cage is designed and built by AST Roll Cages in Spain, for drivers who are turning their M2 into a genuine competition car and are not prepared to compromise on any component.

Key benefits

• Ten welded mounting points plus NASCAR door bars, the most comprehensive combination AST offers for the F87.

• Several curved door tubes for more side protection and, at the same time, more room to get in.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. This is a job for a stripped-out car and an experienced welder: ten welded mounting points have to be bare and clean, and the doors have to be opened up to make room for the curved tubes. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that it fits your car exactly.

Everything AST has for the F87 in one cage: ten welded mounting points, a harness bar and curved door tubes.

Why choose this Multipoint F87 Coupé V4 NASCAR roll cage?

If you are converting your M2 into a competition car, you do not want to discover halfway through the season that a bar is missing. This version brings together the full V4 set of bars, the wide ten-point anchorage and the NASCAR door bars in one package. You pay more for it, but you will not need to have anything added later.

Frequently asked questions

What makes this the most comprehensive version?

The Multipoint F87 Coupé V4 NASCAR has ten welded mounting points where a standard weld-in cage uses eight, the complete V4 bar package including harness bar, and NASCAR door tubes instead of a single door bar.

Can I remove it later?

No, this is a permanent structure. It is welded to the bodyshell and cannot be removed without damaging the car. The manufacturer does not list a homologation number for this product; check the regulations of your own competition organiser.

Does this cage fit a convertible or the G87?

No. This product is designed for the two-door coupé version of the F87. AST does not offer a convertible version for this model, and its successor, the G87, has its own cage, which is not interchangeable with this one.

What is the delivery time?

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