AST Multipoint Weld-in Roll Cage BMW E36 Sedan V4 NASCAR door

The AST Multipoint Weld-in Roll Cage BMW E36 Saloon V4 NASCAR Door Bars is a full roll cage for the BMW E36 with 4-door saloon bodywork. This Multipoint Saloon V4 NASCAR version combines the extra diagonal bars and harness bars of the V4 with NASCAR-style door bars, permanently welded to the bodyshell at 10 points.

The cage is designed and built by AST Roll Cages in Spain, for drivers who want to take both rigidity and driver’s-side protection as far as possible.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. AST has digitised the bodyshell with laser scanners and designed the cage in 3D on that basis, so that the tubes fit your car exactly. Expect to modify the door card for the NASCAR bars, and bear in mind that the extra diagonals further restrict the space in the interior.

The rigidity of the V4 with NASCAR bars alongside the driver, as a single permanently welded-in structure.

Why choose this Multipoint Saloon V4 NASCAR roll cage?

This version stacks two things on top of each other: the extra diagonals and harness bars that make the cage more rigid, and NASCAR door bars that shield the driver in several planes. That makes it the logical choice if the car is being built primarily for function rather than comfort.

Frequently asked questions

What is the difference from the regular V4?

The Multipoint Saloon V4 NASCAR has the same extra diagonals and harness bars, but its door bars run NASCAR-style alongside the driver in several planes rather than in a single plane.

Will the original door card still fit behind it?

Almost never without modification. The NASCAR bars protrude too far into the door opening, so the panel is cut out or replaced with a lighter one.

What is included in the delivery?

The weld-in kit with gussets, reinforcement plates, bolts, washers and nuts, documentation, fitting instructions and a sticker set, all unpainted. This cage is intended for track and competition use; check with your own federation or sporting organisation which requirements apply to your class.
