AST Multipoint Weld-in Roll Cage BMW E30 Sedan V5 NASCAR door

The AST Multipoint Weld-in Roll Cage BMW E30 Sedan V5 NASCAR Door Bars is a full roll cage for the rear-wheel-drive BMW E30 with 4-door saloon bodywork. This Multipoint E30 Sedan V5 NASCAR is the highest specification AST offers for this model, with the complete set of bars, ten welded mounting points and NASCAR door bars in both doors.

The cage is designed and built by AST Roll Cages in Spain, for teams and drivers who are taking their rear-wheel-drive E30 to the absolute limit and do not want to weld anything else in later.

Key benefits

• Complete set of bars, the highest specification in this range.
• Ten welded mounting points anchor the cage to the bodyshell at the maximum number of points.
• Maximum torsional rigidity, because all diagonals, braces and cross-members are included.
• NASCAR door bars with several curved tubes per door instead of the standard door bar.
• More side protection across the full height of the door.
• More room to get in than with a straight door bar, even with this extensive tubework.
• Built once, as there is nothing left to add to this version later.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. This is the most labour-intensive version, as both the number of welded mounting points and the number of tubes are at their highest; strip the interior completely before you start. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so that it fits your car exactly.

The V5 multipoint is the last cage you will ever need to weld into a rear-wheel-drive E30 Saloon.

Why choose this Multipoint E30 Saloon V5 NASCAR roll cage?

Welding in a cage is a job you only want to do once, and with the complete set of bars on ten welded mounting points you close that chapter for good. The combination of maximum rigidity and NASCAR door bars gives you an E30 that stays stable under load, yet is still easy to get in and out of. Everything is drawn to fit this bodyshell, so the kit goes together without improvisation.
