AST Multipoint Weld-in Roll Cage BMW E30 Coupé V3 NASCAR door

The AST Multipoint Weld-in Roll Cage BMW E30 Coupé V3 NASCAR Door Bars is a full roll cage for the BMW E30 with 2-door coupé bodywork. This Multipoint E30 Coupé V3 NASCAR has the same layout as the regular V3, but with several curved tubes in the door instead of the standard door bar. Please note: this is the cage for the rear-wheel-drive E30; a separate cage is available for the all-wheel-drive 325iX.

The cage is designed and built by AST Roll Cages in Spain, for drifters who do a lot of side-by-side driving and therefore want more material in the door than a single bar.

Key benefits

• NASCAR door bars with several curved tubes in the door instead of the standard door bar.
• Better lateral load distribution, as the load is absorbed by several tubes instead of a single bar.
• V3 layout with the front reinforcement bars to the bulkhead, so you also gain in the footwell area.
• Ten welded mounting points on the bodyshell, more than on a standard weld-in cage, resulting in a more rigid shell.
• Custom-scanned, as AST digitises the E30 bodyshell and designs every tube in 3D.
• Complete weld-in kit with gussets, reinforcement plates, bolts, washers, nuts, documentation, fitting instructions and a sticker set.

Fitting and delivery

The cage is built to order; the standard delivery time is 15 to 35 working days. AST digitises the bodyshell with laser scanners and designs the cage in 3D, so it fits your car exactly. Be aware that the doors will need to be stripped: the curved tubes take up the space normally occupied by the door card and the window mechanism. This cage is intended for track and competition use; check your own organiser’s regulations beforehand.

Several curved tubes in the door instead of a single bar: that is what sets NASCAR door bars apart.

Why choose this Multipoint E30 Coupé V3 NASCAR roll cage?

In drifting, contact happens whether you like it or not, and it almost always comes from the side. The Multipoint E30 Coupé V3 NASCAR fills the door with several curved tubes, so an impact is not concentrated on a single point. On top of that, you get the full V3 structure with front reinforcement bars and ten welded mounting points, so your E30 becomes both more rigid and better protected.

Frequently asked questions

What exactly are NASCAR door bars?

On this Multipoint E30 Coupé V3 NASCAR, there are several curved tubes in the door where a conventional cage has a single straight door bar. The tubes follow the shape of the door opening and fill most of it.

What is included?

An unpainted weld-in kit: the tubes of the structure, gussets, reinforcement plates, bolts, washers and nuts, documentation, fitting instructions and a sticker set. You paint the cage yourself after welding it in.

Does this cage also fit a 325iX?

No. The cage follows the floor and transmission tunnel of the rear-wheel-drive E30 Coupé. A separate cage is available for the all-wheel-drive 325iX.

What is the delivery time?

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