AST Weld-in Roll Cage BMW F82 Coupé V4 NASCAR door

The AST Weld-in Roll Cage BMW F82 Coupé V4 NASCAR Door Bars is a full roll cage for the BMW F82 with 2-door coupé bodywork. This Weld-in F82 Coupé V4 NASCAR has several curved tubes in the door instead of the standard door bar and is welded to the bodyshell at eight points.

The cage is designed and built by AST Roll Cages in Spain, for drifters and track drivers who want extra protection from the side without having to squeeze past a single straight door bar every time they drive.

Key benefits

• NASCAR door bars, several curved tubes per door instead of the standard door bar.
• More side protection exactly where contact most often occurs in drifting.
• More room to get in, because the tubes are curved outwards.
• Eight welded mounting points that permanently connect the cage to the bodyshell.
• E355 steel, 45 mm main hoop and 40 mm for the other tubes.
• V4 specification level, with door bars plus an extra diagonal brace and harness bar.
• Unpainted weld-in kit with gussets, reinforcement plates and mounting hardware.

Suitable for

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. The NASCAR tubes extend into the door, so bear in mind that the door panel and door trim have to come out and that welding there is precision work.

The NASCAR door bars give you more steel next to your hip and, at the same time, easier entry than a straight door bar.

Why choose this Weld-in F82 Coupé V4 NASCAR roll cage?

AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that the curved door tubes stay neatly within the door of the F82. For drifting, where side contact is the rule rather than the exception, this is the most sensible door design AST offers for this model.

Frequently asked questions

What exactly are NASCAR door bars?

The Weld-in F82 Coupé V4 NASCAR has several curved tubes in the door instead of the standard door bar. This gives more protection from the side and, at the same time, more room to get in and out.

Does this cage fit a convertible or a G82?

No. This cage has been designed exclusively for the 2-door coupé of the F82. AST does not offer a convertible version for it, and the G82 has its own cage, which is not interchangeable.

Can I take the cage out again later?

No. This is a weld-in version with eight welded mounting points on the bodyshell; the cage becomes a permanent part of the car.
